Customer parameters may be changed repeatedly as a customer's operation changes or as new drivers are assigned to a truck. Customer Passwords are required to change these parameters.
The following information is a brief description of the Customer Specified Parameters. The following parameter values are included with the descriptions:
- Minimum
- Maximum
- Default
The tables show values in an approximate range for metric units that is followed by the metric conversion to English units. The exact range of the parameter in metric units depends on the service tool that is being used. Each tool may use slightly different conversion factors.
Customer Parameter Lockout
The Customer Parameter Lockout is available in order to restrict access to changing some of the available parameters. Locking out a parameter requires Customer Passwords (if used). Once a parameter is locked out, Factory Passwords are required to change the parameter. Also, once a parameter is locked out, Factory Passwords are required to unlock the parameter.
If a lockable parameter is not locked out, Factory Passwords are not required. A locked out parameter restricts the parameter from being changed directly by the operator. This helps vehicle owners that are encountering problems with operators that are obtaining Customer Passwords and altering some of these parameters.
A locked out parameter also provides an audit trail. The audit trail can be used to determine the following information:
- Time of change
- Operator during change
The following Customer Parameters are available for Lockout:
- "Multi-Torque Ratio"
- "Vehicle Speed Calibration"
- "Vehicle Speed Cal (J1939 - Trans)"
- "Vehicle Speed Cal (J1939 - ABS)"
- "Vehicle Speed Limit"
- "VSL Protection"
- "Soft Vehicle Speed Limit"
- "Low Speed Range Axle Ratio"
- "High Speed Range Axle Ratio"
- "Low Cruise Control Set Speed Limit"
- "High Cruise Control Set Speed Limit"
- "Top Engine Limit"
- "Transmission Style"
- "Top Gear Ratio"
- "Top Gear Minus One Ratio"
- "Top Gear Minus Two Ratio"
- "A/C Switch Fan On-Time"
- "Engine Retarder Delay"
- "Engine Monitoring Lamps"
- "Driver Reward Enable"
- "Fan Control Type"
When an attempt to change a locked out parameter occurs, the Factory Password screen will come up. If changing the parameter is required, follow the instructions on ET.
Factory Passwords are also required to change a parameter from a locked parameter to an unlocked parameter. If more than one parameter is locked out, and each one needs to be unlocked, one Factory Password is required.
"Selected Engine Rating"
"Rating Number"
The Rating Number is the selected Rating within a power rating family. The Personality Module defines the power rating family (242 kW (325 hp)) and the Personality Module may contain only one or several ratings. The rating number defines the power rating that is used within the power rating family. The following list illustrates examples of the power rating:
- 324 kW (435 hp) at a Governed Engine Speed of 1800 rpm
- 324 kW (435 hp) at a Governed Engine Speed of 2100 rpm
Both ratings will be displayed for Multi-Torque applications.
"Multi-Torque Ratio"
This parameter is used to select the desired Multitorque trip point. Multitorque ratings allow the engine to provide additional torque, additional horsepower, and torque when the transmission is operating in higher gear. The additional torque allows the truck to crest a hill without downshifting and increases fuel economy. The "Multi-Torque" feature also helps to reduce wear. The trip point is determined by a ratio of engine speed versus vehicle speed. The three programmable options represent the different trip point values that are listed below.
| Programmable Option | Turn On Ratio (RPM to MPH) | Gear Range |
|---|---|---|
| MT-4 | 71.5 | Top 4 Gears |
| MT-2 | 37.6 | Top 2 Gears |
| MT-1 | 27.9 | Top 1 Gear |
Note: This feature is not used with standard engine ratings. This feature is only available for multitorque ratings.
| Type of Engine Rating | Alternatives | Default |
| Standard Ratings | Unavailable | Unavailable |
| Multitorque Ratings | MT-2, MT-1 | MT-4 |
"ECM Identification Parameters"
"Vehicle ID"
"Vehicle ID" is the identification of the vehicle that is assigned by the customer. "Vehicle ID" is used only for the customer's reference. "Vehicle ID" is not required by the ECM.
"Security Access Parameters"
"ECM Wireless Communication Enable"
The "ECM Wireless Communication Enable" determines if the ECM will transfer information over the data link through remote communications systems for customers.
The parameter will default out of Caterpillar to no access. The parameter can only be enabled by getting Factory Passwords. This feature can only be enabled after the truck has been delivered to the customer. Refer to Troubleshooting, "System Overview" for additional information.
| Alternative | Default |
| Yes | No |
"Vehicle Speed Parameters"
"Vehicle Speed Calibration"
The "Vehicle Speed Calibration" is the value that is used by the ECM in order to translate the vehicle speed signal into kilometers per hour (miles per hour). This parameter is programmed in pulses per kilometer (PPKM) or pulses per mile (PPM). This parameter must be programmed. If the "Vehicle Speed Calibration" parameter is not programmed, 253-02 Check Customer or System Parameters (56) will be active. This parameter affects the cruise control and the ECM speedometer signal. Also, this parameter can affect the PTO operation, extended idle and trip totals.
| Minimum | Maximum | Default |
2485 PPKM (4000 PPM) |
93226 PPKM (150000 PPM) |
8696 PPKM (14000 PPM) |
"Vehicle Speed Cal (J1939-Trans)"
NOV01 and newer software
Note: This parameter is not available on engine serial numbers W1A1-UP, MDP1-UP, and MEP1-UP.
The "Vehicle Speed Cal (J1939-Trans)" is used when the ECM is configured to use the speed of the transmission output shaft in order to calculate vehicle speed. The "Vehicle Speed Input" parameter must be programmed to "Vehicle Speed Cal J1939-Trans". This value represents the revolution of the transmission output shaft as revolutions per kilometer (revolutions per mile). This parameter must be programmed. If this parameter is not programmed, the diagnostic code 253-02 that is Check Customer or System Parameters (56) will be active. This parameter affects the cruise control and the ECM speedometer signal. Also, this parameter can affect the PTO operation, extended idle and trip totals.
| Minimum | Maximum | Default |
| 0 | 65000 | Not Programmed |
"Vehicle Speed Cal (J1939-ABS)"
NOV01 and newer software
Note: This parameter is not available on engine serial numbers W1A1-UP, MDP1-UP, and MEP1-UP.
The "Vehicle Speed Cal (J1939-ABS)" is used to calculate vehicle speed by the use of the input from the wheel speed. The data from the wheel speed is transmitted via the J1939 data link. The "Vehicle Speed Input" parameter must be programmed to "Vehicle Speed Cal J1939-ABS". The manufacturer of the ABS system must transmit tire revolutions per mile that is based on the tire size. If the tire size is changed from the tire size that is programmed in the ABS system, the "Vehicle Speed Cal (J1939-ABS)" must be changed. The value that is contained in the "Vehicle Speed Cal (J1939-ABS)" parameter is a ratio. If the actual tire size is equal to the tire size that is programmed in the ABS system, the "Vehicle Speed Cal (J1939-ABS)" parameter will be "1". The ratio can be found by dividing the tire revolutions per mile that is transmitted by the ABS system by the actual tire revolutions per mile. Contact the manufacturer of the ABS system in order to verify that this message is supported.
If the "Vehicle Speed Input" parameter is programmed to "Vehicle Speed Cal J1939-ABS", this parameter must be programmed. If this parameter is not programmed, the diagnostic code 253-02 that is Check Customer or System Parameters (56) will be active. This parameter affects the cruise control and the ECM speedometer signal. Also, this parameter can affect the PTO operation, extended idle and trip totals.
| Minimum | Maximum | Default |
| 0 | 6.550 | Not Programmed |
"Vehicle Speed Limit" (VSL)
The "Vehicle Speed Limit" (VSL) is the maximum vehicle speed that is allowed by the ECM. The ECM will shut off fuel above this speed. An inexperienced driver may think that something is wrong with the engine because the ECM will not fuel the engine above this vehicle speed limit. Vehicle speed limiting allows the implementation of a gear fast/run slow specification for the truck. The gear fast/run slow specification for the truck improves fuel economy while the parameter for the vehicle speed limit limits the maximum vehicle speed of the truck.
Note: The Driver Incentive Feature can be used to automatically adjust the VSL according to the driver's operating techniques.
| Minimum | Maximum | Default |
48 km/h (30 mph) |
204 km/h (127 mph) |
204 km/h (127 mph) |
"VSL Protection"
The "VSL Protection" is the maximum engine rpm when there is a problem with the vehicle speed signal that is detected by the ECM. The ECM limits the engine to this engine rpm when the ECM senses no vehicle speed signal, and a load on the engine. This is a feature that is used to prevent tampering by running without a Vehicle Speed input to the ECM.
Note: When this parameter is programmed to 2120 rpm, the ECM disables 84-01 Loss Of Vehicle Speed Signal (31) and 84-10 Vehicle Speed Rate of Change (36) and the "VSL Protection" may be exceeded by disconnecting the Vehicle Speed Sensor.
| Minimum | Maximum | Default |
| 1300 rpm | 2120 rpm | 2120 rpm |
"Tachometer Calibration"
The "Tachometer Calibration" is used by the ECM to translate the engine speed signal into revolutions per minute for a tachometer. The "Tachometer Calibration" is programmed in pulses per revolution (PPR). The programmable range is from 12.0 PPR to 500.0 PPR in 0.1 PPR increments.
| Minimum | Maximum | Default |
| 12.0 PPR | 500.0 PPR | 113.0 PPR |
"Soft Vehicle Speed Limit"
The "Soft Vehicle Speed Limit" operates in conjunction with the "Vehicle Speed Limit". The "Soft Vehicle Speed Limit" limits the vehicle speed within the following range:
- The minimum value is 4 km/h (2.5 mph) below the programmed "Vehicle Speed Limit" at full load.
- The maximum value is 4 km/h (2.5 mph) above the selected "Vehicle Speed Limit" at no load.
| Alternative | Default |
| Yes | No |
"Low Speed Range Axle Ratio"
The "Low Speed Range Axle Ratio" must be programmed when a "Two-Speed Axle On/Off Switch" is used by the ECM to adjust the "Vehicle Speed Calibration". When a two-speed axle is used, the change in gear ratios from the high speed range to the low speed range alters the calibration of the vehicle speed signal. Since the vehicle speed signal has been altered, a calibration adjustment is required to ensure that the ECM driven speedometer and the information that is stored in the ECM correctly reflect the actual vehicle speed. This parameter should be programmed to the "Low Speed Range Axle Ratio". This parameter only requires programming when the "Two-Speed Axle Switch" parameter is enabled. The "Two-Speed Axle Switch" Parameter is enabled when the parameter is programmed to J1/P1:7, J1/P1:47, J1/P1:6, or J1/P1:46.
| Minimum | Maximum | Default |
| 1.00 | 19.99 | 1.00 |
"High Speed Range Axle Ratio"
The "High Speed Range Axle Ratio" must be programmed when a "Two-Speed Axle On/Off Switch" is used by the ECM to adjust the "Vehicle Speed Calibration". When a two-speed axle is used, the change in gear ratios from the high speed range to the low speed range alters the calibration of the vehicle speed signal. Since the vehicle speed signal has been altered, a calibration adjustment is required to ensure that the ECM driven speedometer and the information that is stored in the ECM correctly reflect the actual vehicle speed. This parameter should be programmed to the "High Speed Range Axle Ratio". This parameter only requires programming when the "Two-Speed Axle Switch" parameter is enabled. The "Two-Speed Axle Switch" parameter is enabled when the parameter is programmed to J1/P1:7, J1/P1:47, J1/P1:6, or J1/P1:46.
| Minimum | Maximum | Default |
| 1.00 | 9.99 | 1.00 |
"Cruise Control Parameters"
"Low Cruise Control Speed Set Limit"
The "Low Cruise Control Speed Set Limit" sets the lowest vehicle speed that will allow the cruise control to be set. Programming this parameter to the maximum value disables cruise control.
| Minimum | Maximum | Default |
24 km/h (15 mph) |
204 km/h (127 mph) |
204 km/h (127 mph) |
"High Cruise Control Speed Set Limit"
The "High Cruise Control Speed Set Limit" sets the highest vehicle speed that will allow the cruise control to be set. If a driver attempts to set a vehicle speed higher than this limit, the "High Cruise Control Speed Set Limit" will be the cruise set speed. If the "High Cruise Control Speed Set Limit" is programmed to a value that is greater than the Vehicle Speed Limit, the cruise control switches can be used to exceed the programmed Vehicle Speed Limit.
| Minimum | Maximum | Default |
48 km/h (30 mph) |
204 km/h (127 mph) |
204 km/h (127 mph) |
"Engine Retarder Mode"
"Engine Retarder Mode" determines the operation of the Auxiliary Retarder Output and the Exhaust Retarder Output while the cruise control On/Off switch is in the ON position but the engine is not in cruise control. This does not determine engine retarder operation while the engine is in cruise control. Also, this does not allow engine retarder operation while the engine is in cruise control.
The following modes are allowable options:
- Coast
- Latch
- Manual
When the "Engine Retarder Mode" is programmed to the Coast mode, the engine retarder is enabled only while the service brakes are being applied. When the ECM is programmed to the Latch mode, the engine retarder stays enabled after the service brakes are released. A direct, immediate pressure on the brake pedal latches the engine retarder in the ON position and the engine retarder will remain in the ON position until the accelerator pedal is depressed.
When the ECM is programmed to the Manual mode, the cruise control switch is not required to be in the ON position. When the ECM is programmed to the Manual mode, the engine retarder will activate when all of the following conditions are met:
- The engine retarder switch is in the ON position.
- The engine rpm is greater than 800 rpm.
- The engine is not being fueled.
| Alternative | Default |
| Coast or Latch | Manual |

Coast and latch of engine retarder mode | |
"Engine Retarder Minimum VSL Type"
The "Engine Retarder Minimum VSL Type" defines the use of the "Engine Retarder Minimum Vehicle Speed" parameter. The "Engine Retarder Minimum VSL Type" provides the following two options:
- Hard Limit
- Soft Limit
If the "Engine Retarder Minimum VSL Type" is programmed to the Hard Limit, the engine retarder will turn off when the value that is programmed into the Engine Retarder Minimum Vehicle Speed is reached.
If the "Engine Retarder Minimum VSL Type" is programmed to the Soft Limit, the engine retarder will remain on and the retarder will have a value that is below the value that is programmed in the Engine Retarder Minimum Vehicle Speed. The engine retarder will remain on until the parameters that would normally turn off the engine retarder are met.
In both cases, the engine retarder will remain off until vehicle speed is higher than the programmed value of the Engine Retarder Minimum Vehicle Speed and the engine retarder has been engaged again.
The following diagram illustrates the Engine Retarder operation for both options of the "Engine Retarder Minimum VSL Type". The Engine Retarder parameter is programmed to MANUAL and the parameter for the Engine Retarder Minimum Vehicle Speed is programmed to 48 km/h (30 mph).
 | |
| Illustration 2 | g00631048 |
Note: When the vehicle speed drops below the Engine Retarder Minimum Vehicle Speed and the parameter is programmed to the Hard limit, the engine retarder turns off. When the vehicle speed drops below the Engine Retarder Minimum Vehicle Speed and the parameter is programmed to the Soft limit, the Engine retarder remains on.
If the Engine Retarder Minimum Vehicle Speed has been programmed to 0 km/h (0 mph), the programming of the parameter for the "Engine Retarder Minimum VSL Type" does not affect the operation of the Engine Retarder.
| Alternative | Default |
| Soft Limit | Hard Limit |
"Engine Retarder Minimum Vehicle Speed"
Engine Retarder Minimum Vehicle Speed determines the minimum vehicle speed limit for the engine retarders to turn ON. Below this vehicle speed, the ECM will not turn on the engine retarder unless the vehicle is stationary. If the vehicle is stationary, the vehicle speed is 0 km/h (0 mph). If the vehicle speed signal was not being read by the ECM, the vehicle could be moving but the vehicle speed signal would be 0 km/h (0 mph). If Engine Retarder Minimum Vehicle Speed is programmed to 0 km/h (0 mph) the engine retarder will operate at all vehicle speeds. This parameter affects both the engine retarder and any auxiliary retarder such as a BrakeSaver.
| Minimum | Maximum | Default |
0 km/h (0 mph) |
204 km/h (127 mph) |
0 km/h (0 mph) |
"Auto Retarder in Cruise"
The "Auto Retarder in Cruise" determines the vehicle speed in kilometers per hour (km/h) or miles per hour (mph) above the cruise set speed when the engine retarder will be activated. The engine retarder switch must be in the ON position and the cruise control must be set for this feature to operate. Programming the "Auto Retarder in Cruise" parameter to zero disables this feature. This parameter affects the engine while the cruise control is activated.
Note: This parameter only affects the Factory installed engine retarder (compression brake). This parameter does not affect an auxiliary braking device or Brakesaver.
The actual level of braking is limited by the settings of the retarder switch. For example, the retarder will not come on if the retarder is switched off.
If Soft Cruise Control is programmed to YES, the retarder will not come on until the vehicle speed is 5 km/h (3 mph) above the cruise set speed. An Electronic Service Tool will change an attempt to program 2 km/h (1 mph) or 3 km/h (2 mph) for this parameter to 5 km/h (3 mph) if Soft Cruise Control is programmed to YES.
| Minimum | Maximum | Default |
0 km/h (0 mph) |
16 km/h (10 mph) |
0 km/h (0 mph) |
"Auto Retarder in Cruise Increment"
"Auto Retarder in Cruise Increment" requires the "Auto Retarder in Cruise" parameter to be programmed above zero. "Auto Retarder in Cruise Increment" determines the increment in kilometers per hour (km/h) or miles per hour (mph) when the Medium level of engine retarder will activate. "Auto Retarder in Cruise Increment" also determines the increment in kilometers per hour (km/h) or miles per hour (mph) when the High level of engine retarder will activate. Programming the parameter to zero will allow the retarder to come on in the High mode when the programmed "Auto Retarder in Cruise" speed is reached. The "Auto Retarder in Cruise" speed must be set above the cruise set speed. This parameter affects the engine while the cruise control is activated. The actual level of braking is limited by the settings of the retarder switch. For example, the retarder will not come on if the retarder is switched off.
| Minimum | Maximum | Default |
0 km/h (0 mph) |
8 km/h (5 mph) |
3 km/h (2 mph) |
"Cruise/Idle/PTO Switch Configuration"
"Cruise/Idle/PTO Switch Configuration" defines the function of the Set/Resume Switch for "ACCEL" mode and "DECEL" mode. This parameter affects cruise control mode, idle mode and PTO mode.
| Alternative | Default |
| Set/Decel-Res/Accel | Set/Accel-Res/Decel |
"Soft Cruise Control"
"Soft Cruise Control" provides a 8 km/h (5 mph) operating range around the cruise control set speed in order to provide a smoother cruise control. "Soft Cruise Control" controls the cruise speed within the following range:
- 4 km/h (2.5 mph) below the set vehicle speed at full load
- 4 km/h (2.5 mph) above the set vehicle speed at no load
 | |
| Illustration 3 | g00670797 |
| Alternative | Default |
| No | Yes |
"Adaptive Cruise Control Enable"
Adaptive cruise control reduces the need to manually cancel cruise control when you approach a slower vehicle. The system responds by decreasing the cruise control set speed until a following distance is obtained. If the slower vehicle speeds up, the cruise control set speed will be adjusted in order to maintain the following distance. Adaptive cruise control will restore the original set speed when there are no vehicles within the range of control. Adaptive cruise control will not increase the cruise control set speed above the original setting. If the vehicle is approaching the target too rapidly, the ECM will turn off the cruise control.
| Alternative | Default |
| Enabled | Disabled |
"Idle Parameters"
"Idle Vehicle Speed Limit"
The "Idle Vehicle Speed Limit" is the maximum vehicle speed for setting or maintaining a set engine rpm in the idle mode. In order to enter the idle mode, the engine rpm must be set by the Set/Resume switch while the Cruise Control On/Off switch is in the ON position. If the vehicle speed signal exceeds this value, the engine will not maintain the set engine rpm.
| Minimum | Maximum | Default |
2 km/h (1 mph) |
24 km/h (15 mph) |
2 km/h (1 mph) |
"Idle RPM Limit"
The "Idle RPM Limit" is the maximum engine rpm in idle mode. The idle mode occurs if the engine rpm is set by the use of the Cruise Control On/Off switch and the Set/Resume switch. Refer to "Idle Vehicle Speed Limit". The actual high limit of this parameter is determined by the programmed Top Engine Limit. The lower limit is determined by the programmed "Low Idle Engine rpm".
Programming this parameter to 600 rpm will prevent the engine from idling at a constant rpm above the programmed Low Idle rpm.
| Minimum | Maximum | Default |
| 600 rpm | TEL rpm | TEL rpm |
"Idle/PTO RPM Ramp Rate"
The "Idle/PTO RPM Ramp Rate" determines the rate of increase or decrease of engine rpm. This parameter determines rates of increase or decrease in engine rpm for the following functions:
- Idle rpm
- PTO rpm
The parameter can be set to a value between 5 rpm and 1000 rpm in one rpm increments.
Note: The parameter affects both idle control and PTO control. The idle mode occurs if the engine rpm is set by the use of the Cruise Control On/Off switch and the Set/Resume switch. The PTO mode occurs if the engine rpm is set by the use of the "PTO On/Off" switch and the Set/Resume switch.
| Minimum | Maximum | Default |
| 5 rpm/sec | 1000 rpm/sec | 50 rpm/sec |
"Idle/PTO Bump RPM"
The "Idle/PTO Bump RPM" determines the increment or the decrement in engine rpm when the ACCEL switch or the DECEL switch is briefly toggled. The "Idle/PTO Bump RPM" also pertains to the dedicated PTO and idle. If a "PTO Engine RPM Set Speed" has been programmed, the "Idle/PTO Bump RPM" pertains only to the control of the engine rpm that is initiated by the use of the "Cruise Control On/Off" input circuit. If a PTO Engine rpm Set Speed has been programmed, the "Idle/PTO Bump RPM" also pertains to the control of the engine rpm that is initiated by the use of the "PTO On/Off" circuit.
| Minimum | Maximum | Default |
| 5 rpm | 500 rpm | 20 rpm |
"Dedicated PTO Parameters"
"PTO Configuration"
The "PTO Configuration" determines the features that are available for Dedicated PTO applications and the input signals that are used for Dedicated PTO applications. When the "PTO Configuration" is turned off, the application does not use the PTO. The remaining PTO programmable options require a "PTO On/Off" circuit that is connected to ECM Input 1. A PTO Switch On Lamp can also be connected to Output 1 (ECM J1/P1:30).
If the ECM is programmed to the Cab Switches, the ECM will use the signals from the following two switches for PTO Control and Cruise Control:
- Cab Set switch (J1/P1:35)
- Resume switch (J1/P1:44)
If the ECM is programmed to "Remote Switches", the ECM will monitor programmed signals such as the Remote Set switch and the Remote Resume switch. Signals from the cab controls will be ignored when the "PTO On/Off" circuit is on. The following components are cab controls:
- Brake Switch
- Clutch Switch
- Accelerator
- Cruise Control Switches
If the ECM is programmed to "Remote Throttle", the ECM will monitor J1/P1:68 for the remote accelerator pedal. The ECM will monitor programmed signals and the ECM will ignore all cab controls when the "PTO On/Off" circuit is ON.
| Alternative | Default |
| Cab Switches Remote Switches Remote Throttle |
Off |
"PTO Top Engine Limit"
The "PTO Top Engine Limit" is the top engine limit that is available by the use of a "PTO On/Off" circuit that is connected to Input 1 of ECM Connector J1/P1.
Note: The "PTO Configuration" must be programmed to Cab Switches, Remote Switches, or Remote Throttle before this parameter can be programmed.
| Minimum | Maximum | Default |
| 600 | TEL rpm | TEL rpm |
"PTO Engine RPM Set Speed (0 = Off)"
This parameter allows automatic ramping to the preset rpm when the PTO is engaged. "PTO to Set Speed" must be programmed to "Yes" for this parameter to function. When the PTO is engaged the rpm will change according to the programmed "PTO Ramp Rate". This parameter is only available when the "PTO Configuration" is programmed to "Cab Switches", "Remote Switches", or "Remote Throttle".
| Minimum | Maximum | Default |
| Low Idle | PTO TEL rpm | 0 |
"PTO Engine RPM Set Speed A"
NOV99 and newer software
The ECM controls this engine rpm. This control occurs when the "PTO ON/OFF" circuit is on and the "PTO Engine RPM Set speed Input A" switch is on. The RPM can be programmed to operate from Low Idle up to the PTO Top Engine Limit RPM. While the engine is operating at this set speed, all other inputs for speed control are ignored. The inputs for speed control that are ignored include the Cab Throttle switch, the Remote Throttle switch, the Set/Accel switch, and the Resume/Decel switch. This feature can also be used in conjunction with the "PTO to Set speed" feature and the "PTO Engine RPM Set Speed B" feature for multiple speed PTO operation. This feature can also override the "PTO to Set speed" feature and the "PTO Engine RPM Set Speed B" feature for multiple speed PTO operation.
The engine will only operate at this programmed speed when the "PTO ON/OFF" circuit is on and the "PTO Engine RPM Set Speed Input A" switch is on. The engine will operate at the programmed speed unless a condition that causes PTO operation kickout occurs. The conditions that will cause PTO operation kickout include the depression of the brake pedal, the depression of the clutch pedal, and the "PTO Vehicle Speed Limit" that is exceeded. The engine will return to low idle if the PTO operation is kicked out.
Note: The "PTO Configuration" parameter must be programmed to Cab Switches, Remote Switches, or Remote Throttle and the "PTO Engine RPM Set Speed Input A" parameter must be programmed to a dedicated switch input (J1/P1:6, J1/P1:46, J1/P1:58, or J1/P1:60) for this feature to function.
| Minimum | Maximum | Default |
| Low Idle rpm | PTO TEL rpm | 0 rpm |
"PTO Engine RPM Set Speed Input B"
NOV99 and newer software
The ECM controls this engine rpm. This control occurs when the "PTO ON/OFF" circuit and the "PTO Engine RPM Set Speed Input B" switch is on and the "PTO Engine RPM Set Speed A" switch is off. The RPM can be programmed to operate from Low Idle up to the "PTO Top Engine Limit" RPM. While the engine is operating at this set speed, all other inputs for speed control are ignored except for the "PTO Engine RPM Set Speed A". The inputs for speed control that are ignored include the Cab Throttle switch, the Remote Throttle switch, the Set/Accel switch, and the Resume/Decel switch. This feature can also be used in conjunction with the "PTO to Set speed" feature for multiple speed PTO operation. This feature can also override the "PTO to Set speed" feature for multiple speed PTO operation.
The engine will only operate at this programmed speed when the "PTO ON/OFF" circuit and the "PTO Engine RPM Set Speed Input B" switch is on and the "PTO Engine RPM Set Speed A" switch is off. The engine will operate at the programmed speed unless a condition that causes PTO operation kickout occurs. The conditions that will cause PTO operation kickout include the depression of the brake pedal, the depression of the clutch pedal, and the "PTO Vehicle Speed Limit" that is exceeded. The engine will return to low idle if the PTO operation is kicked out.
Note: The "PTO Configuration" parameter must be programmed to Cab Switches, Remote switches, or Remote Throttle and the "PTO Engine RPM Set Speed Input B" parameter must be programmed to a dedicated switch input (J1/P1:6, J1/P1:46, J1/P1:58, or J1/P1:60) for this feature to function.
| Minimum | Maximum | Default |
| Low Idle rpm | PTO TEL rpm | 0 rpm |
"PTO to Set Speed"
This parameter causes the ECM to proceed to the programmed "PTO Engine RPM Set Speed" when the "PTO ON/OFF" switch is on. "PTO Configuration" must be programmed to Cab Switches or Remote Switches before this parameter can be programmed.
Note: This parameter is not available for "PTO Configuration Remote Throttle".
| Alternative | Default |
| Yes | No |
"Maximum PTO Enable Speed"
NOV01 and newer software
Note: This parameter is not available on engine serial numbers W1A1-UP, MDP1-UP, and MEP1-UP.
This parameter specifies the maximum engine speed for the engagement of the PTO mode. The PTO mode will engage when the engine rpm is equal to the programmed limit or less than the programmed limit. This parameter is only available when the "PTO Configuration" is programmed to "Cab Switches", "Remote Switches", or "Remote Throttle".
| Minimum | Maximum | Default |
| Low Idle rpm | TEL rpm | TEL rpm |
"PTO Cab Controls RPM Limit"
This determines the engine rpm limit of the cab mounted Accelerator Pedal Position Sensor when "PTO Configuration" is programmed to "Cab Switches" and the "PTO On/Off" circuit is on. This parameter is intended to prevent engine overspeed when dedicated PTO is used.
- If the parameter is programmed to Low Idle, the Cab Controls are ignored.
- If the parameter is programmed to "Top Engine Limit" (TEL), the engine will operate to the programmed "Top Engine Limit".
- If the parameter is programmed to "PTO TEL", the engine will operate to the programmed "PTO Top Engine Limit".
Note: "PTO Configuration" must be programmed to Cab Switches for this parameter to take effect. If "PTO Configuration" is programmed to Remote Switches or Remote Throttle, the ECM will always ignore the Cab Throttle when the "PTO On/Off" circuit is on.
| Alternative | Default |
| Low Idle TEL PTO TEL |

| Illustration 4 | g00628600 |
Operation of Torque limit (1) Programmed torque limit | |
The parameter for the "Torque Limit" defines the maximum torque output of the engine during Dedicated PTO operation. This parameter provides temporary protection of equipment. The Torque limit of the engine is active when the circuit for the Torque Limit Switch is on. The maximum value is the Rated Torque of the engine. The "Torque Limit" is programmable to N·m (lb ft) of torque. Programming a value higher than the Rated Torque is limited by the ECM to Rated Torque. The torque limit is indicated by the dashed line in Illustration 4.
| Minimum | Maximum | Default |
270 N·m (200 lb ft) |
3400 N·m (2500 lb ft) |
3400 N·m (2500 lb ft) |
"PTO Shutdown Time"
The "PTO Shutdown Time" sets the amount of idle time before the PTO shuts down. The time begins when the "PTO On/Off" circuit is on and there is no vehicle speed. The PTO Shutdown Timer will not begin counting if the engine is in Cold Mode. This parameter requires the "PTO Configuration" to be programmed to Cab Switches, Remote Switches or Remote Throttle for the timer to function.
Note: This feature does not shut down the vehicle's power. The ECM and the vehicle remain powered.
| Minimum | Maximum | Default |
| 3 minutes | 1440 minutes | 0 minutes |
"PTO Shutdown Timer Maximum RPM"
OCT99 and newer software
This parameter can be used to reset the PTO Shutdown Timer if engine speed goes above the programmed "PTO Shutdown Timer Maximum RPM". Programming this parameter to 2120 rpm disables this feature. If this parameter is programmed to a value below 2120 rpm and the PTO Shutdown Timer is used, the timer will be reset when the engine RPM exceeds the programmed value.

"PTO Activates Cooling Fan"
This parameter requires the use of the ECM cooling fan circuit. When this parameter is programmed to Continuous Mode, the ECM will signal the cooling fan to run continuously when the "PTO On/Off" circuit is on. The cooling fan runs continuously in order to reduce changes in the load while the engine is being used for dedicated PTO applications. When this parameter is programmed to the normal mode, the operation of the fan is based on coolant temperature, inlet air temperature or air conditioning high head pressure. The "PTO Configuration" must be programmed to "Cab Switches", "Remote Switches" or "Remote Throttle" before this parameter can be programmed. The "Fan Control Type" must be programmed to the "On/Off" setting or the "Three-Speed Fan Setting".
| Alternative | Default |
| Continuous | Normal |

"Timer Parameters"
"Idle Shutdown Time"
The "Idle Shutdown Time" is the time (minutes) of engine idle before shutting down. The engine will only shut down if the ECM senses low engine load and no vehicle speed. The Idle Shutdown Timer will not begin counting if the engine is in Cold Mode. If this parameter is programmed to zero, this feature is disabled and the engine will idle until the keyswitch for the ignition is in the OFF position.
Note: This feature does not shut down the vehicle's power. The ECM and the vehicle remain powered.
| Minimum | Maximum | Default |
| 3 minutes | 1440 minutes | 0 minutes |
"Idle Shutdown Timer Maximum RPM"
NOV99 and newer software
This parameter can be used to reset the "Idle Shutdown Timer" if engine speed goes above the programmed "Idle Shutdown Timer Maximum RPM". Programming this parameter to 2120 rpm disables this feature. By disabling this feature, the "Idle Shutdown Timer" can not be overridden by increasing the engine rpm. If this parameter is programmed to a value below 2120 rpm and the "PTO Shutdown Timer" is used, the timer will be reset when the engine RPM exceeds the programmed value.
| Minimum | Maximum | Default |
|---|---|---|
| 600 rpm | 2120 rpm | 2120 rpm |
"Allow Idle Shutdown Override"
This parameter determines if the clutch or the service brake can be used to override the idle shutdown timer during the driver alert. The driver alert is the last 90 seconds when the Check Engine Lamp begins flashing. This parameter requires the "Idle Shutdown Time" to be programmed to 3 or more minutes for the parameter to be enabled. When the "Idle Shutdown Time" is programmed to 0, the parameter is turned off.
In order to override the timer under the following conditions, depress the clutch or the service brake if the parameter is programmed to "Outside Temperature Based" or "J1587 Outside Temperature Based" and the driver alert is activated. Depression of the clutch or the service brake will override the timer:
- The outside temperature is below the programmed "Minimum Idle Shutdown Outside Temperature".
- The outside temperature is above the" Maximum Idle Shutdown Outside Temperature".
Note: When the timer is overridden, the engine will not shut down.
If the outside temperature is between the "Minimum Idle Shutdown Outside Temperature" and the "Maximum Idle Shutdown Outside Temperature", the timer is not overridden and the engine will shut down. If the Outside Temperature Based option is programmed, an Air Temperature Sensor must be installed in order to measure the outside temperature. If the sensor is not installed, a 171-03 Outside Air Temp Sensor Open Circuit diagnostic code will be active. If the J1587 Outside Temperature Based option is programmed and a 171-11 No Ambient Air Temperature Data active diagnostic code exists, the idle shutdown timer will be disabled.
| Alternative | Default |

49 °C (120 °F) |
"A/C Switch Fan On-Time"
The input 11 to the ECM can be used for the connection of a normally closed high pressure A/C switch. The ECM has a built-in timer. The timer is used to prevent excessive cycling of the cooling fan clutch due to successive cycling of the A/C switch. Programming this parameter to 0 disables the function. Programming depends on the refrigerant, and the design of the air conditioning system as well as the use of the signal input. Program the timer to 1 second for the connection of this input to another system. Programming the timer to 1 second also provides a time delay. This feature requires the "Fan Control Type" to be programmed to the On/Off or the "Three-Speed Fan".
| Minimum | Maximum | Default |
| 1 second | 600 seconds | 0 seconds |
"Fan with Engine Retarder in High Mode"
This parameter determines whether the Cooling Fan will turn on when the Engine Brake has been active for at least two seconds.

| Minimum | Maximum | Default |
| 0 seconds | 3 seconds | 0 seconds |
"Smart Idle Parameters"
"Battery Monitor and Engine Control Voltage"
OCT99 and newer software
This parameter is used to determine the voltage trip point. Below this trip point, the Battery Monitor and the Engine Speed Control System will automatically elevate engine idle in order to maintain ideal battery system voltage. This feature is used to promote additional battery life. The engine idle will only be increased if the vehicle is stopped and the transmission is out of gear. If these conditions are not met, the engine idle will not be adjusted. This feature will not function when the engine is operating in dedicated PTO mode ("PTO On/Off" switch in the ON position).
The recommended setting is 12.2 Volts for a 12 Volt system, and 24.5 Volts for a 24 Volt system.
Note: This feature requires the installation of a Neutral Switch on J1/P1. This is terminal 62 (Input 12). Engine speed will only be elevated when the transmission is in Neutral.
| Minimum | Maximum | Default |
|---|---|---|
| 0 Volts | 25.5 Volts | 0 Volts |
"Engine Monitoring Parameters"
"Engine Monitoring Mode"
This parameter determines the level of action that will be taken by the ECM in response to a condition that has the capability to damage the engine. The ECM reads the Caterpillar Coolant Temperature, Oil Pressure and Inlet Manifold Air Temperature. If the ECM has been programmed to monitor the OEM Installed Coolant Level Sensor, the ECM will read that sensor.
Note: NOV01 and newer software does not allow the "Engine Monitoring Mode" to be programmed to "Off" except on engine serial numbers W1A1-UP, MDP1-UP, and MEP1-UP.
| Alternative | Default |

This parameter determines the lamp requirements for the Engine Monitoring System. If this parameter is programmed to the Warning Lamp option, J1/P1:29 is available for the connection of a red Warning Lamp. The Warning Lamp is used to alert the operator that an engine problem is occurring. The Warning Lamp also indicates when the engine is being derated or the lamp will indicate that shutdown will take place.
If this parameter is programmed to Option 1, there will be up to three discrete lamp outputs that are available for use to indicate specific engine problems. "Option 1" configures J1/P1:29 for the connection of a Low Oil Pressure Lamp and "Option 1" also configures J1/P1:31 for the connection of a High Coolant Temperature Lamp. If the parameter for the Coolant Level Sensor is programmed to the 4 Pin option, then J1/P1:30 will also be available for the connection of a Low Coolant Level Warning Lamp. If the parameter for the Coolant Level Sensor is programmed to Off, then J1/P1:30 can be used to connect a PTO Switch On Lamp.
| Alternative | Default |

"Trip Parameters"
"Fuel Correction Factor"
The "fuel correction factor" is available to fine tune all fuel data that will be stored in the future by the ECM. Caterpillar recommends changing this factor only after a significant operating interval that includes a comparison of actual tank fuel economy to the fuel economy that is recorded in the ECM. The operating interval should also reflect a typical route. The "Fuel Correction Factor" is a percentage that is programmable in 0.5 percent increments.
| Minimum | Maximum | Default |
| -63.5 | +63.5 | 0 |
"Calculating Fuel Correction Factor"
The following formula should be used to determine the new Fuel Correction Factor (NEW FCF).
 | |
| Illustration 7 | g00629908 |
OLD FCF - Fuel Correction Factor in ECM
TANK - Actual Fuel Economy

"Dash Display Access Parameters"
The following parameters establish a security access for the Caterpillar Driver Information Display:
- "Change Fuel Correction Factor"
- "PM 1 Reset"
- "Fleet Trip Reset"
- "State Selection"
These parameters require a Caterpillar Driver Information Display for access.
"Change Fuel Correction Factor"
This parameter allows the driver to adjust the "Fuel Correction Factor". An owner/operator would want the driver to be able to change this information, but a fleet operation might not want the driver to be able to change this information.
| Alternative | Default |
| Yes | No |
"PM 1 Reset"
This parameter determines the driver's access for resetting the PM 1 (Maintenance) after the PM 1 has been performed. Maintenance Indicator Mode cannot be programmed to "OFF" for the "PM 1 Reset" parameter to take effect.
| Alternative | Default |
| Yes | No |
"Fleet Trip Reset"
This parameter determines the driver's access for resetting the Fleet Trip Segment.
| Alternative | Default |
| Yes | No |
"State Selection"
Program this parameter to NO to disable this function of the Cat ID. The Cat ID will not show "State Selection" as an option to the driver. If this parameter is programmed to "YES" (default) the Cat ID will provide the feature of "State Selection".
Programming this parameter to "NO" eliminates "State Selection". Therefore, the storage of the trip data ("State Selection") is eliminated.
| Alternative | Default |
| No | Yes |
"Theft Deterrent System Control"
When this parameter is used with a "Theft Deterrent Password", this parameter prevents the engine from starting unless the password has been entered via the dash display of the CAT ID. Before the operator can use the feature of Theft Deterrent of the CAT ID, the system must be turned on. In order to turn on the theft deterrent, a service tool must be used to program the parameter for the theft deterrent to "YES". The operator must first enter the password before the engine is shut off. This will enable the system. Enabling the system prevents the engine from starting without re-entering the password on the next attempted start.
| Alternative | Default |
| Yes, Auto-Enable (1) | No |
| ( 1 ) | NOV99 and newer software |
"Theft Deterrent Password"
The "Theft Deterrent Password" is the password that is required by the ECM before the feature of Theft Deterrent is enabled. After the Theft Deterrent is enabled, the "Theft Deterrent Password" is the password that is required to restart the engine. All of the characters must be in the upper case.
| Alternative | Default |
| Four Characters A through Z 0 through 9 |
0000 |
"Quick Stop Rate"
This parameter determines the rate of vehicle speed change that is used by the ECM to record a Quick Stop Event Code and a Quick Stop Snapshot. This parameter is programmable from 5 kilometers per hour per second (3 miles per hour per second) to 24 kilometers per hour per second (15 miles per hour per second). This parameter is also programmable to 0, which is the default value. Programming this parameter to 0 will disable this feature and no Quick Stop Events will be logged. Each Quick Stop Snapshot contains 60 frames of information. The no. 45 Frame is the "Quick Stop occurrence". The Quick Stop Snapshot also contains 44 frames before the "Quick Stop occurrence" and 15 frames after the "Quick Stop occurrence". Each frame is separated by 1.0 second.
| ECM Snapshot Frame Data | |
| Engine rpm Throttle Position Clutch Switch |
Vehicle Speed Cruise Status Brake Switch |
The most recent Quick Stop Snapshot is stored in the ECM memory. When a Quick Stop Event occurs the ECM replaces the old Quick Stop Snapshot with the new Quick Stop Snapshot. The ECM also logs a diagnostic event code for each "Quick Stop Occurrence". The ECM stores a maximum of 255 occurrences.
| Alternative | Default |
| 5 kilometers per hour per second ( 3 miles per hour per second) to 24 kilometers per hour per second (15 miles per hour per second) | 0 kilometers per hour per second (0 miles per hour per second) |
Note: Programming the "Quick Stop Rate" too low will cause an excessive number of Quick Stop Event Codes. A vehicle without a load or a trailer will be able to stop much more quickly than a vehicle with a heavy load. If too many Quick Stop Event Codes are being logged, the "Quick Stop Rate" should be increased. This will improve the detection of the exceptions when the exceptions occur.
"Vehicle Activity Report"
"Minimum Idle Time"
OCT99 and newer software
The "Vehicle Activity Report" provides a chronological order log of engine operation. This report records the following items: "vehicle starts", "vehicle stops", "idle time", "driving time" and "PTO time". The "Minimum Idle Time" parameter can be used to adjust the recorded idle time. This is done in order to remove the time for the following occurrences: stopped in traffic, switching into PTO mode and switching out of PTO mode and idling for other brief periods of time. If the "Minimum Idle Time" is programmed to a value above 0 minutes (default), the previous mode of operation will be logged until the idle time exceeds the programmed limit.
| Minimum | Maximum | Default |
|---|---|---|
| 0 Minutes | 1440 Minutes | 0 Minutes |
"Driver Reward"
"Driver Reward Enable"
MAR99 and newer software
"Driver Reward" is a feature that allows a truck owner to place emphasis on certain factors for desired operating habits. If the vehicle is operated in a manner that exceeds the owner's specifications, the maximum vehicle speed limit can be automatically increased to a specified value as a reward to the driver. The "Driver Reward Enable" parameter provides a means in order to disable the "Driver Reward" feature. This parameter also provides a means in order to lock out the "Driver Reward" feature. An Electronic Service Tool is used for those areas with regulations that require a fixed maximum Vehicle Speed Limit.
| Alternatives | Default |
