SRPR XMSN ECM     J1-20     892-BR    Expected Result:The resistance that is measured is less than 5 ohms for each measurement.Results:
OK. - The resistance that is measured is less than 5 ohms for each measurement. The data link circuit is correct. The ECM may have failed.Repair: It is unlikely that the ECM has failed. Exit this procedure and perform this diagnostic code procedure again.Prior to replacing an ECM, always contact your dealership's "Technical Communicator" for possible consultation with Caterpillar. This consultation may greatly reduce repair time. If the cause of the diagnostic code is not found and the ECM must be replaced, refer to Troubleshooting, "Electronic Control Module (ECM) - Replace".STOP
NOT OK. - The resistance that is measured is greater than 5000 ohms for one or more of the measurements. The machine harness has failed.Repair: Repair the machine harness or replace the machine harness. Proceed to Test Step 8.Test Step 8. CHECK THE STATUS OF THE DIAGNOSTIC CODE
The disconnect switch and the key start switch remain in the ON position.
Operate the machine.
Determine if the CID 0967 FMI 02 diagnostic code is active.Expected Result:The CID 0967 FMI 02 diagnostic code is not active.Results:
OK. - The CID 0967 FMI 02 diagnostic code is not active. The diagnostic code does not exist at this time. Resume normal operation.STOP
NOT OK. - The CID 0967 FMI 02 diagnostic code is active. The diagnostic code has not been corrected.Repair: It is unlikely that the ECM has failed. Exit this procedure and perform this procedure again. If the cause is not found, contact the Technical Communicator at your dealership for possible consultation with Caterpillar. This consultation may greatly reduce repair time. If the cause of the diagnostic code cannot be found, replace the ECM. Refer to Troubleshooting, "Electronic Control Module (ECM) - Replace".STOP
