Diagnostic Codes Table
Description Conditions which Generate this Code System Response
268-2 Check Programmable Parameters The engine's Electronic Control Module (ECM) detects that one or more of the programmable parameters have not been programmed. The ECM may use a default torque map or the ECM may limit the engine to low idle.
The code is active only.
253-2 Personality Module mismatch The flash file in the engine's ECM is for a different type of engine. The interlock code in the non-volatile memory does not match the flash file.
or
The flash file is not compatible with the ECM. The interlock for the personality module code must be set to zero in order to reset the code. Factory passwords are required to change the interlock code.
The code is active only. The engine may not run.
1495-2 Injector Trim Codes Not Programmed The engine's ECM detects that one or more of the injector trim codes have not been programmed. The ECM may use a default torque map or the ECM may limit the engine to low idle.
The code is active only. System configuration parameters are parameters that affect emissions, power of the engine, and other features. The parameters are programmed at the factory. In most cases, the parameters do not need to be changed. The system configuration parameters must be reprogrammed if an ECM is replaced and/or the engine rating is reprogrammed. System configuration parameters do not need to be reprogrammed if the flash file is replaced. Proper values for these parameters are available on Caterpillar Electronic Technician (ET). Certain configuration parameters are also stamped on the engine information plate.Note: Changing the parameters that are protected by factory passwords may cause your Caterpillar warranty to be voided.
Check Programmable Parameters (268-02)
If a programmable parameter has not been programmed, the ECM will activate a 268-02 Check Programmable Parameters. The unprogrammed parameters will be set to default. Certain aspects of the engine's performance and engine monitoring may be affected.Personality Module Mismatch (253-02)
The ECM stores a code number in permanent memory. This code is called an interlock code that is associated with each flash file. The interlock code does not allow the engine to run if the wrong flash file has been downloaded into the ECM.Cat ET will warn you if a flash file that does not match the last file in the ECM has been downloaded. The interlock code must be reprogrammed with Cat ET in order to allow the engine to run with new software. For instructions on reprogramming the interlock code, refer to the Special Instruction, SEHS9343. Installing the incorrect flash file into the ECM may void the Caterpillar warranty.The 3500 ECM and another Caterpillar ECM may appear to be similar, but the electronic control modules are different. These different electronic control modules cannot be interchanged. For example, a 3412E ECM cannot be used to replace a 3500 ECM. The interlock code can not be reset if the wrong ECM is installed. If an incorrect ECM is used, a 253-02 Personality Module Mismatch becomes active. The fuel injection is disabled in order to prevent the engine from starting. Verify the correct ECM part number by checking the part number that is listed in the Parts Manual.When the engine is rerated, programming the interlock code to zero will prompt the ECM. The ECM will read the stored code and the ECM will match the stored code to the new interlock code.Engine Serial Number
Program the engine serial number to match the engine information plate. The serial number is not programmed on a new ECM.Rated Fuel Position
This parameter is used to set engine power. A factory password is required to change this setting.
Table 2
Minimum Default Maximum
Minimum Rack Engine Dependent Engine Dependent Low Idle
The parameter defines the lowest rpm level.
Table 3
Minimum Default Maximum
450 rpm 600 rpm 1000 rpm Cooldown Speed
This parameter defines the engine speed when the engine is in cooldown mode.
Table 4
Minimum Default Maximum
450 rpm 600 rpm 1800 rpm Engine Cooldown Duration
This parameter defines engine operation at the cooldown speed. Programming this parameter to 0 will disable this function.
Table 5
Minimum Default Maximum
0 minutes 0 minutes 60 minutes Engine Prelube Duration
The parameter sets the amount of time for prelubrication. Programming this parameter to 0 will disable this function.
Table 6
Minimum Default Maximum
0 seconds 0 seconds 210 seconds Crank Duration
The crank duration determines the amount of time that the starting motors are energized. Programming this parameter to 0 will prevent the ECM from engaging the starting motors.
