Information:
System Operation Description:The Electronic Control Module (ECM) is the computer which controls the engine. The Personality Module contains the software that determines the function of the ECM. The two must be used together.The ECM consists of the following items:
A microprocessor that will execute the following ECM functions: governing, injection timing control, system diagnostics and data link communication
A permanent memory that stores programmable parameters and diagnostic codes
Input circuits that filter electrical noise from sensor signals
Input circuits that protect internal circuits in the ECM from potentially damaging voltage levels
Output circuits that provide high voltage for the injector solenoids and relays
Power circuits that provide a clean, stable, electrical power for the injector solenoids, internal circuits, and external sensorsThe Personality Module consists of the following items:
The personality module contains all of the software for the ECM. Updating the personality module to a different version may cause some engine features to behave differently.
Control maps define such operating conditions as timing and fuel rates. These maps help to achieve optimum engine performance and fuel consumption. The maps are programmed into the Personality Module at the factory.The Personality Module on earlier engines could be updated only by the removal of the module from the ECM. A module that contained a different program would then be installed. A new type of memory chip which can be programmed through the use of the Caterpillar Electronic Technician (ET) is now used. This is called "FLASH" memory. "FLASH" memory has the advantage of retaining programmed information indefinitely and "FLASH" memory can be reprogrammed without opening the case of the ECM. This process of Flash Programming is accomplished through the use of Cat ET. Refer to the diagnostic procedure Troubleshooting, "Flash Programming".Note: The Personality Module can still be removed and replaced. Flash Programming is the preferred method for reprogramming a Personality Module.

Personality ModuleNote: The Engine Control Switch (ECS) is mounted within an instrument panel that is located on the right side of the engine. The ECS is locked into the AUTO position with a pin. The pin must be removed in order to perform this test. After performing this test, ensure that the ECS is placed in the AUTO position and that the locking pin has been reinstalled.Test Step 1. Check for "ACTIVE" Codes.
Turn the ECS to the OFF/RESET position.
Connect the Cat ET.
Turn the ECS to the ON position. The engine should be off.
Check for active diagnostic codes.Results:
253-02 Present - Proceed to test step 2.
254-12 Present - If an internal problem develops, the diagnostic code 254-12 becomes active. This indicates that the ECM has detected an internal problem that cannot be fixed.Repair: Replace the ECM. Ensure that the new ECM serial number ends in CD. Refer to the diagnostic procedure Troubleshooting, "Replacing the ECM" before replacing the ECM. Stop.
268-02 Present - Repair: Reprogram the system configuration parameters. Refer to the diagnostic procedure Troubleshooting, "System Configuration Parameters" for additional information. Stop.Test Step 2. Check for a Personality Module Mismatch.
Verify that the correct ECM has been installed.
Check the ECM part number.
