This condition indicates a "Customer Specified Parameter" or a system configuration parameter that requires programming has not been programmed. Once this parameter has been programmed, the code may still be active. This can happen if there is yet another parameter that requires programming.
System Response:
Electronic System Response The fault is active only and the fault is not logged. If the Personality Module Code of the new personality module does not match the code of the old personality module, the engine is limited to low idle. If the "Rating Number" has not been programmed, the ECM limits the engine to 89.5 kW (120.0 hp). When a new ECM is initially powered up, the following parameters must be programmed to avoid this diagnostic code:
- "Full Load Setting" (FLS)
- "Full Torque Setting" (FTS)
- "Vehicle Speed Calibration"
- "Rating Number"
- "Engine Serial Number"
Service Tool Display or Lamps Caterpillar Electronic Technician (ET) will display a list of the parameters that require programming. If two or more Multi I/O parameters are programmed to the same input/output, only one of the Multi I/O parameters will be listed at one time. If the list of parameters exceeds the limit, the Multi I/O parameters will not be listed until some of the other parameters are corrected. This will make space on the list in order to display the Multi I/O parameters. The Check Engine Lamp will illuminate.
Engine Response The ECM will limit the engine to low idle if the parameter is the FLS or the FTS. The ECM may also limit the power if the parameter is a rating number.
Test Step 1. Perform the following diagnostic procedure: ECM Memory - Test
Results:
- OK - STOP
