Diagnostic Codes Table    
Code and Description    Conditions which Generate this Code    System Response    
268-2 Programmed Parameter Fault erratic, intermittent, or incorrect     The engine's Electronic Control Module (ECM) detects that one or more of the programmable parameters have not been programmed.     The ECM will set the unprogrammed parameter(s) to a default value.
The code is logged.    If the 268-02 diagnostic code is active, program the missing parameter.System configuration parameters are parameters that affect emissions, power of the engine, and machine applications. 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. You must reprogram the system configuration parameters if the ECM is replaced and/or if you reprogram the engine rating. Values for these parameters are available on Caterpillar Electronic Technician (ET). Certain configuration parameters are also stamped on the engine information plate.Parameter Descriptions
"Equipment ID"
The "Equipment ID" parameter allows the customer to enter a description into the ECM in order to identify the machine. A maximum of 17 characters can be entered in the field."Engine Serial Number"
Program the "Engine Serial Number" to match the engine serial number that is stamped on the engine information plate. The engine serial number is not preprogrammed on a replacement ECM."FLS" (Full Load Setting)
"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. Only change this value if the engine is rerated or if a new ECM is installed. The parameter allows one time of programming without a factory password. In order to change the "FLS" after the initial programming, factory passwords are required."FTS" (Full Torque Setting)
"FTS" is similar to "FLS". Only change this value if the engine is rerated or if a new ECM is installed. Factory passwords are required. A new ECM or a blank ECM allows one time of programming of the "FTS" without the use of factory passwords. In order to change the "FTS" after the initial programming, factory passwords are required.Parameter Table
