Schematic of the "Autolube Relay"This diagnostic code is associated with the "Autolube Relay". The FMI 05 diagnostic code means that the ECM has determined that an open in the circuit exists. The possible causes of this diagnostic code are listed below:
The energize circuit of the relay is open.
The return circuit of the relay is open.
The relay has failed.
The Chassis ECM has failed. The failure of the ECM is unlikely. Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 0558 FMI 05 is active before performing this procedure.Note: Use a digital multimeter for the measurements in this procedure.Test Step 1. CHECK THE RELAY.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
Disconnect the relay with the active diagnostic code from the machine harness.
At the machine harness connector for the relay, place a jumper wire from contact C8 (wire H469-YL) to contact E7 (wire H808-WH).
Observe the status of the CID 0558 FMI 05 diagnostic code.Expected Result:The diagnostic
