PIN 2120136 - Caterpillar

System Operation Description:This procedure covers the following diagnostic codes:
252-11 Engine Software Incorrect (59)
253-02 Check Customer or System Parameters (56)
253-14 Truck Manufacturer Parameter Not PogrammedBackground Information252-11The flash file in the ECM is from the wrong engine family. The engine will not start.253-02At least one of the following conditions exists:
One or more of the configuration parameters are not programmed. The effect on the engine depends on the parameter.
The personality module code of the flash file in the ECM is different from the personality module code of the original flash file. Engine speed is limited to low idle.
At least two programmable inputs are programmed to the same input terminal or at least two programmable outputs are programmed to the same output terminal. Engine speed is limited to low idle.
All of the injector trim files are not loaded into the ECM. Engine performance and emissions are affected.Several of the above conditions can exist at the same time. The conditions that exist are displayed beneath the code. The 253-02 diagnostic code will disappear when all of the conditions have been resolved.253-14The "Truck Manufacturer" parameter has not been programmed. The following items will not work correctly:
Speedometer
Tachometer
Engine monitoring lampsTest Step 1. Correct the ConditionDetermine the diagnostic code that is active.Expected Result:A 252-11, 253-02, or 253-14 diagnostic code is active.Results:
A 252-11 code is active - Repair: Obtain the engine serial number. Use SIS to determine the latest available flash file for the engine. Verify that the latest available flash file is loaded into the ECM.STOP
A 253-02 code is active - Repair: Identify the condition that is displayed beneath the code:If a programmable parameter is displayed, program that parameter with the correct value.If a programmable input or a programmable output is displayed, identify all of the inputs and/or the outputs that are programmed to the same value. Program the inputs and/or the outputs to match the vehicle's actual configuration.If "Injector Code" is displayed, load the missing injector trim file into the ECM. Refer to Troubleshooting, "Injector Trim File".If "Personality Module Code" is displayed, perform one of the following actions:
Program the latest available flash file into the ECM.
Obtain factory passwords in order to reset the rating interlock code.STOP
A 253-14 code is active - Repair: Determine the type of chassis. If the engine is installed in a General Motors chassis, program the "Truck Manufacturer" parameter to "GM". For all other chassis, program the parameter to "Other".STOP
