If the Electronic Control Module (ECM) is replaced and/or you reprogram the engine rating then the "ECM Identification Parameters" must be programmed.
Some values may be changed by the customer in order to suit the needs of the specific application. The values are programmed with the Caterpillar Electronic Technician (ET).
If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.
Note: The "ECM Identification Parameters" must be programmed if the ECM is replaced and/or you reprogram the engine rating. It is not necessary to reprogram the "ECM Identification Parameters" if a new flash file is programmed into the ECM.
The system configuration parameters are arranged in groups. Refer to Table 1.

Parameter Descriptions
"Engine Rating Information"
"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 the Original Equipment Manufacturer (OEM) will need to select the appropriate rating tier, if more than one rating tier is present. The rating tier is A through E.
"ECM Identification Parameters"
"Equipment ID"
"Equipment ID" allows the customer to enter a description into the ECM in order to identify the engine. A maximum of 17 characters may be entered in the field. This parameter is used as a 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 can be obtained from the engine information plate. Use this information to program the parameter.
Note: When you are requesting factory passwords, always use the engine serial number that is resident in the ECM.
"Engine/Gear Parameters"
"Engine Location"
Note: The "Number of Synchronized Engines Configuration", "Engine Location", and "Secondary Throttle Enable Status" must be programmed in the following order:
- "Number of Synchronized Engines Configuration"
- "Engine Location"
- "Secondary Throttle Enable Status"
"Number of Synchronized Engines Configuration"
This parameter must be programmed to the number of synchronized engines that are used in the application. If this parameter is programmed to two or more engines, the "Secondary Throttle Enable Status" parameter is automatically programmed to "Enabled".
Note: The "Number of Synchronized Engines Configuration", "Engine Location", and "Secondary Throttle Enable Status" must be programmed in the following order:
- "Number of Synchronized Engines Configuration"
- "Engine Location"
- "Secondary Throttle Enable Status"
"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.
"Fuel Air Ratio Control Adjust (FARC)" ( C12)
This allows the customer to adjust the engine's transient response. The adjustment allows the customer to choose an engine response that is faster with some smoke to a slower response with no smoke. The "Fuel Air Ratio Control" can be programmed to three different levels of response by the customer:
Level 1 - The leanest setting for the fuel air ratio control that has the slowest response to throttle input
Level 2 - A richer setting for the fuel air ratio control that has a quicker response to throttle input
Level 3 - The richest setting for fuel air ratio control that has the quickest response to throttle input
No passwords are required to change the parameter.
"Low Idle Speed"
"Low Idle Speed" is the minimum allowable operating speed for the engine.
"Maximum Trolling Engine Speed"
The ECM must limit the engine speed when the engine is in trolling mode. This prevents damage to the clutch. The maximum engine speed is set to the value of this parameter when the engine is in trolling mode. The value of this parameter must be higher than the value of the "Low Idle Speed" parameter.

"Secondary Throttle Enable Status"
Note: The "Number of Synchronized Engines Configuration", "Engine Location", and "Secondary Throttle Enable Status" must be programmed in the following order:
- "Number of Synchronized Engines Configuration"
- "Engine Location"
- "Secondary Throttle Enable Status"
"Tachometer Frequency Configuration"
This parameter allows the ECM to be calibrated for a specific tachometer. The allowable range is from 12 to 500 pulses per revolution. The default value is 113.
"System Operating Voltage Configuration"
At the time of this publication, this parameter is not active.
"Cold Cylinder Cutout" ( 3406E, C15, and C18)
This parameter is programmed in order to increase the stability of the engine during cold mode operation.
The cold cylinder cutout will turn off cylinders four, five, and six when the following conditions are present:
- An override for the cylinder cutout is not active.
- A cylinder fault is not active.
- The engine is in cold mode.
"Optional Sensor Parameters"
"Transmission Oil Temperature Sensor"
The "Transmission Oil Temperature Sensor" parameter instructs the ECM to monitor the input for the sensor. Engine monitoring for this sensor is enabled if the parameter is programmed to "Installed".
"Transmission Oil Pressure Sensor"
The "Transmission Oil Pressure Sensor" parameter instructs the ECM to monitor the input for the sensor. Engine monitoring for this sensor is enabled if the parameter is programmed to "Installed".
"Coolant Level Sensor"
The "Coolant Level Sensor" parameter instructs the ECM to monitor the input for the sensor. Engine monitoring for this sensor is enabled if the parameter is programmed to "Installed".
"Fuel Level Sensor"
The "Fuel Level Sensor" parameter instructs the ECM to monitor the input for the sensor. Engine monitoring for this sensor is enabled if the parameter is programmed to "Installed".
"Low Fuel Level Warning Threshold"
The "Low Fuel Level Warning Threshold" parameter sets the threshold for the illumination of a warning lamp for low fuel. The "Fuel Level Sensor" parameter must be programmed to "Installed" for this functionality to be enabled.
Maintenance Parameters
"Engine Oil Capacity"
This parameter should be programmed to match the actual engine oil capacity.
"Fuel Correction Factor"
The Fuel Correction Factor (FCF) fine tunes all of the fuel data that will be stored in the future by the ECM. Caterpillar recommends changing the FCF only after an operating interval that allows a comparison of actual fuel economy to the fuel economy that is calculated by the ECM for typical operating conditions. The allowable range is −64 to +63.5. The default value is zero.
Calculating the Error
Error = [(Actual fuel economy − Economy calculated by the ECM) ÷ Actual fuel economy] × 100
Calculating the New Fuel Correction Factor
New FCF = Old FCF + [(100 + Old FCF) × Error] ÷ 100
Note: The old FCF is the FCF that is currently programmed in the ECM.
"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 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.
Passwords
"Customer Password #1"
This parameter allows the customer to lock out certain parameters by entering a password. Customer passwords must be used to unlock any parameters that are protected by customer passwords before the parameter can be changed. Factory passwords are required if this password is lost.
"Customer Password #2"
This parameter allows the customer to lock out certain parameters by entering a password. Customer passwords must be used to unlock any parameters that are protected by customer passwords before the parameter can be changed. Factory passwords are required if this password is lost.

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. When any of these conditions occur, the appropriate event code will trip.
Note: Refer to Troubleshooting, "Troubleshooting with an Event Code" for additional information.
