Schematic of the VIMS service indicator lamp
This diagnostic code is recorded when the VIMS electronic control module reads the current of the service indicator lamp circuit (wire E709-WH(White)) and the current is below normal. System Response:The service indicator lamp will not light if this diagnostic code is present.Test Step 1. CHECK THE SERVICE INDICATOR LAMP.
Turn the disconnect switch and the key start switch to the OFF position.
Replace the service indicator lamp with a known working lamp.
Turn the disconnect switch and the key start switch to the ON position.
Verify that the diagnostic code CID 0823 FMI 05 is no longer present. Expected Result:The diagnostic code CID 0823 FMI 05 is no longer present.Results:
OK - The diagnostic code CID 0823 FMI 05 is no longer present. The lamp was open.Repair: Replace the service indicator lamp.STOP
NOT OK - The diagnostic code CID 0823 FMI 05 is still active. The action lamp is not causing the fault. Proceed to test step 2.Test Step 2. CHECK THE MACHINE HARNESS
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect machine harness connector J1 from the VIMS ECM.
Measure the resistance between contact J1-58 (wire E709-WH(White)) and contact J1-59 (wire J848-BU(Blue)) of the machine harness connector. Expected Result:The resistance is approximately 50 ohms.Results:
OK - The resistance is approximately 50 ohms. The harness is correct. The VIMS ECM has failed.Repair: It is unlikely that the ECM has failed. Exit this procedure and perform this procedure again. If the fault is not found, replace the ECM. Refer to the Testing and Adjusting, "Module - Replace".STOP
NOT OK - The resistance is greater than 5000 ohms. The harness is open.Repair: Check the signal circuit and the return circuit. Repair the machine harness or replace the machine harness.STOP
