CID 0712 FMI 06 Lamp (Retarder Indicator) Current Above Normal - Test
This diagnostic code is recorded when the ARC reads the current in the circuit (wire 454-GN-16) of the retarder indicator lamp as above normal. As a result of this condition, the retarder indicator lamp will not illuminate.
- CHECK THE INDICATOR LAMP.
- Wire 454-GN-16 should be disconnected from the socket of the retarder indicator lamp at the retarder indicator lamp.
Expected Result: The CID 0712 FMI 06 diagnostic code is present.
Results:
- OK: The CID 0712 FMI 06 is present. The retarding indicator lamp is not causing the diagnostic code. Proceed to Step 2.
- NO: The CID 0712 FMI 06 is NO longer present. The indicator lamp is faulty or the socket of the indicator lamp is faulty. Replace the retarding indicator lamp. STOP.
Note: The correct resistance for an indicator lamp is greater than 10 ohms for the purposes of this procedure.
- OK: The CID 0712 FMI 06 is present. The retarding indicator lamp is not causing the diagnostic code. Proceed to Step 2.
- Wire 454-GN-16 should be disconnected from the socket of the retarder indicator lamp at the retarder indicator lamp.
- CHECK THE HARNESS.
- Turn the disconnect switch to the OFF position.
- Wire 454-GN-16 remains disconnected from the retarding indicator lamp.
- Disconnect the machine harness from the ARC.
- Measure the resistance between connector A-A5 (wire 454-GN-16) and frame ground at the machine harness connector for the ARC.
Expected Result: The resistance is greater than 5000 ohms.
Results:
- OK: The resistance is greater than 5000 ohms. The harness resistance is correct. Proceed to Step 3.
- NO: The resistance is less than 5000 ohms. The harness is faulty. Repair the machine harness or replace the machine harness. STOP.
- OK: The resistance is greater than 5000 ohms. The harness resistance is correct. Proceed to Step 3.
- CHECK THE ARC.
- Remove contact A-A5 from the machine harness connector for the ARC.
- Reconnect the harness connector to the ARC.
- Turn the disconnect switch and the key start switches to the ON position.
- Check the status of the diagnostic code. The diagnostic code is active or the diagnostic code is NOT active.
Expected Result: The CID 0712 FMI 06 diagnostic code is active.
Results:
- OK: The CID 0712 FMI 06 diagnostic code remains active. The ARC is faulty. Replace the ARC. See Testing And Adjusting, "ARC - Replace". STOP.
- NO: The CID 0712 FMI 06 diagnostic code is NOT active. The ARC is not causing the diagnostic code. The diagnostic code is intermittent. The probable cause of the diagnostic code is a poor electrical connection at the harness connectors or a damaged harness. Check the harness for damage. Clean the harness connectors if it is necessary. STOP.
- OK: The CID 0712 FMI 06 diagnostic code remains active. The ARC is faulty. Replace the ARC. See Testing And Adjusting, "ARC - Replace". STOP.
