System configuration parameters are parameters that affect emissions and power of the engine applications. Default values for the parameters are programmed at the factory. Some parameters may be changed by the customer in order to suit the needs of the specific application.
Parameter Descriptions
"Equipment ID"
"Equipment ID" allows the customer to enter a description into the Electronic Control Module (ECM) in order to identify the machine. A maximum of 17 characters may be entered in the field. This parameter is only for reference by the customer. This parameter is not required.
"Engine Serial Number"
Program the "Engine Serial Number" to match the engine serial number that is stamped on the engine information plate. If the ECM is replaced, the engine serial number from the engine information plate must be programmed into the new ECM.
Note: When you are requesting factory passwords, always use the engine serial number that is programmed in the ECM.
"Rating Number"
The "Rating Number" corresponds to the selected set of performance maps for the application. This selected set of performance maps comes out of several unique sets of maps that may be resident in the flash file. The dealer and/or Caterpillar will need to select the appropriate rating tier, if more than one rating tier is present. The rating tier is A through E.
"Top Engine Limit" (TEL)
 | |
| Illustration 1 | g00763900 |
"TEL" is a customer programmable parameter that defines the maximum allowable engine speed for maximum power. "TEL" can be programmed up to the maximum rated engine speed. "TEL" is defined along the engine's lug curve.
"Engine Accel. Rate"
"Engine Accel. Rate" determines the rate of change of the engine speed.
"Low Idle Speed"
"Low Idle Speed" is the minimum allowable operating speed for the engine. This parameter can be programmed between 600 and 1400 rpm.
"PTO Mode"
"PTO Mode" allows the ECM to be programmed to either one of the two PTO configurations that are available.
"Ramp Up/Ramp Down" - When "PTO Mode" is programmed to "Ramp Up/Ramp Down", the ECM allows PTO operation with traditional features.
"Set/Resume" - When "PTO Mode" is programmed to "Set/Resume", the ECM allows PTO operation with enhanced features.
"High Idle Speed"
| | |
| Illustration 2 | g00763900 |
"High Idle Speed" is the maximum no-load engine speed when the throttle or the PTO switch is in the maximum position.
Note: "High Idle Speed" cannot be programmed lower than "TEL".
"Intermediate Engine Speed"
"Intermediate Engine Speed" defines the speed for the engine when the intermediate engine speed switch is activated. This parameter can be programmed to any engine speed between "Low Idle Speed" and "TEL". Engine speed will increase or engine speed will decrease at the rate that is defined by the programmed value for "Engine Accel. Rate".
"Engine Power Trim"
"Engine Power Trim" allows small adjustments to be made to engine power within a selected rating. This parameter is expressed as a percentage. This parameter will allow the lug curve to be adjusted by the programmed value.
"Maximum Engine Torque Limit"
 | |
| Illustration 3 | g00817759 |
"Engine Torque Limit" can be used to limit torque output to the programmed value when the torque limit switch is activated.
"FLS" (Full Load Setting)
"FLS" is a number that represents the adjustment to the fuel system that was made at the factory in order to fine tune the fuel system. The correct value for this parameter is stamped on the engine information plate. Factory passwords are required.
"FTS" (Full Torque Setting)
"FTS" is similar to "FLS". Factory passwords are required.
"Ether Control"
Program the "Ether Control" to "Enabled" if an ether injection system is installed on the engine. This allows the ECM to control ether injection. If the engine is not equipped with ether, program this parameter to "Disabled".
"Air Shutoff"
"Air Shutoff" allows the ECM to be programmed for operation of an air shutoff system. If this parameter is programmed to "Installed", the ECM will activate the air shutoff solenoid in the event of an engine overspeed condition.
Note: If an engine overspeed condition occurs and "Air Shutoff" is programmed to "Enabled", the switched power to the ECM must be cycled and the air shutoff solenoid must be manually reset before the engine will restart.
"Maintenance Indicator Mode"
The ECM records data that is related to equipment maintenance. The ECM will activate the maintenance indicator lamp when scheduled maintenance is due. The maintenance indicator lamp can be reset by actuating the maintenance clear switch. The maintenance interval may be based on operating hours or on fuel consumption. The ECM provides information that pertains to maintenance intervals and the last maintenance that was performed.
"PM1 Interval"
"PM1 Interval" allows the customer to define the maintenance interval if "Maintenance Indicator Mode" is programmed to one of the manual options. Refer to the Operation and Maintenance Manual for more information.
"Throttle Position Sensor"
Program the "Throttle Position Sensor" to "Installed" if a throttle position sensor is used for desired speed control. Otherwise program this parameter to "Not Installed".
"Coolant Level Sensor"
Program the "Coolant Level Sensor" to "Installed" if a coolant level sensor is installed on the engine. Otherwise program this parameter to "Not Installed".
"Direct Fuel Control Mode"
Program the "Direct Fuel Control Mode" to "Enabled" if an external governor is used. Once this parameter is enabled, the governing system in the ECM is disabled. Otherwise program this parameter to "Disabled".
"Aux Press Sensor Installation Status"
Program "Aux Press Enable" to "Installed" if an auxiliary pressure sensor is installed. This will allow the display for the engine monitoring system to monitor the pressure of another system. Otherwise program this parameter to "Not Installed".
"Aux Temp Sensor Installation Status"
Program "Aux Temp Enable" to "Installed" if an auxiliary temperature sensor is installed. This will allow the display for the Engine Monitoring System (EMS) to monitor the temperature of another system. Otherwise program this parameter to "Not Installed".
"Desired Speed Input Configuration"
Program the "Desired Speed Input Configuration" to match the type of input signal for desired engine speed. The ECM must be programmed to "CAN Input" if the throttle signal is transmitted over the J1939 data link. The ECM must be programmed to "PWM" if a throttle position sensor or direct fuel control is used.
"Throttle Input Low Idle Duty Cycle Setpoint & LO%SET"
This parameter can be used to set the duty cycle for low idle. If the throttle position sensor that is used will not reach 10 percent duty cycle, the duty cycle can be increased up to a maximum of 40 percent.
"Throttle Input High Idle Duty Cycle Setpoint & HI%SET"
This parameter can be used to set the duty cycle for high idle. If the throttle position sensor that is used will not reach 90 percent duty cycle, the duty cycle can be decreased to a minimum of 50 percent.

Note: Compare the FLS and the FTS from the ECM with the values that are listed on the engine information plate. Only change the FLS and the FTS because of a mechanical change in the engine. The use of the wrong parameters could cause damage to the engine. The use of the wrong parameters may also void the Caterpillar warranty.
Monitoring System
The monitoring system determines the level of action that is taken by the ECM in response to a condition that can damage the engine. The monitoring of the various sensors by the ECM can be turned "On" or "Off". These conditions are identified by the ECM from the signals that are produced from the following sensors.
- Engine oil pressure sensor
- Engine coolant temperature sensor
- Engine speed/timing sensors
- Inlet air temperature sensor
- Coolant level sensor
- Fuel temperature sensor
- Fuel pressure sensor
- Auxiliary temperature sensor
- Auxiliary pressure sensor
Note: The monitoring system can be locked out. In order to change the settings, the monitoring system must be unlocked. Access the "Parameter Lockout" under the "Service" menu on the Caterpillar Electronic Technician (ET) in order to unlock the monitoring system.
