Diagnostic Codes Table    
Description     Conditions which Generate this Code     System Response    
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.    
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.    System configuration parameters are parameters that affect emissions and power of the engine. Some system configuration parameters are configurable by the customer in order to suit the customer's 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 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. Values for these parameters can be viewed 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.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.Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.If a programmable parameter has not been programmed, the ECM will generate a 268-2 diagnostic code. The unprogrammed parameters will be set to default. Certain aspects of the engine's performance and engine monitoring may be affected. Program the missing parameter.If an injector code has not been programmed, the ECM will generate a 1495-2 diagnostic code. The injector code is a number that is found on each of the unit injectors. The ECM uses this number to compensate for manufacturing variations between individual injectors. If you replace any of the unit injectors, you must reprogram the code for the new injectors. Also, if you replace the ECM, you must reprogram all of the injector codes.Note: The injector codes are not part of the "Configuration" screen on the electronic service tool. "Injector Codes Calibration" can be found under "Calibrations" in the "Service" menu on Cat ET.Parameter Table
