Diagnostic Codes Table    
Description     Conditions which Generate this Code     System Response    
268-2 Check Programmable Parameters     The engine 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 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 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.    Some system configuration parameters are configurable by the customer in order to suit the customer particular application. The configuration file contains all of the adjustable settings for the monitoring system. The engine is shipped from the factory with default values for these parameters. In most cases, the parameters do not require change. The system configuration parameters must be reprogrammed if an ECM is replaced and/or the engine rating is reprogrammed. System configuration parameters remain the same 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.If the default settings for the parameters have been modified, there will be no record at the factory of the changes. These settings can be downloaded into a laptop computer and saved to a file. The customer can then use the file in order to ease the future replacement of the ECM.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 parameter has not been programmed, the ECM will activate a 268-02 diagnostic code. The unprogrammed parameters will be set to default. Certain aspects of the engine 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. Installing the incorrect flash file into the ECM may void the Caterpillar warranty.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.Equipment ID
The customer can assign an "Equipment ID" for identification. The "Equipment ID" is not a required parameter. The "Equipment ID" can be any 17 characters.Engine Serial Number
Program the engine serial number to match the engine information plate. The serial number is not programmed on a new ECM.Full Load Setting (FLS)
This parameter represents the adjustment for the fuel system in order to fine-tune the fuel system maximum fuel delivery. A factory password is required to change this setting.

Minimum     Default     Maximum    
-128     Not Programmed     +127    Full Torque Setting (FTS)
This parameter is similar to the FLS. A factory password is required to change this setting.
Table 3
Minimum     Default     Maximum    
-128     Not Programmed     +127    Rated Fuel Position
This parameter is used to set engine power. A factory password is required to change this setting.
Table 4
Minimum     Default     Maximum    
Minimum Rack     Engine Dependent     Engine Dependent    Low Idle
The parameter defines the lowest rpm level.
Table 5
Minimum     Default     Maximum    
450 rpm     600 rpm     1000 rpm    Fuel Correction Factor (FCF)
The FCF is used to adjust the calculation of fuel consumption. The FCF is used to correct the estimated fuel rate.

-25     0     25    Cooldown Speed
This parameter defines the engine speed when the engine is in cooldown mode.
