Description     Conditions which Generate this Code     System Response     Procedure    
268-2 Programmed Parameter Fault erratic, intermittent, or incorrect     The Electronic Control Module (ECM) detects that one or more of the programmable parameters have not been programmed.     The engine performance may be affected by unprogrammed parameters. The unprogrammed parameters determine the action that is taken by the ECM. The ECM may use a default torque map or the ECM may limit the engine to low idle.     Program the missing parameter.    
1495-2 Injector Trim Codes Not Programmed     The ECM detects that one or more of the injector trim codes has not been programmed. The ECM has been powered for three seconds.     The code is logged in memory. The engine will start. The ECM will use a default setting of 0000 for an unprogrammed injector trim code.     Program the missing injector trim code.    System configuration parameters are parameters that affect emissions and power of the engine. Default values for the parameters are programmed at the factory. Some parameters may be changed by the customer in order to suit the needs of the specific application. Values for these parameters can be viewed on Caterpillar Electronic Technician (ET). Certain configuration parameters are also stamped on the engine information plate.No password is required for programming a new ECM during the first 100 hours of service life. This 100 hour "free configuration" feature enables the customer to tailor the programmable setpoints to the requirements of the installation. Exceptions are "Fuel Limit" and "Personality Module Mismatch".Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.Parameter Table

"Personality Module Interlock"
The "Personality Module Interlock" is automatically programmed by the ECM after factory passwords are entered."ECM Serial Number"
The "ECM Serial Number" is stored in the memory of the ECM. The "ECM Serial Number" can be accessed by the use of the service tool."Engine Serial Number"
Program the "Engine Serial Number" to match the engine serial number that is stamped on the engine information plate.Note: When you are requesting factory passwords, always use the engine serial number that is resident in the ECM."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 only for reference by the customer. This parameter is not required."Full Load Setting (FLS)"
"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."Full Torque Setting (FTS)"
"FTS" is similar to "FLS". Factory passwords are
