Schematic for the Raise Solenoid
This diagnostic code is associated with the raise solenoid valve. The FMI 05 means that the ECM has determined that an open in the circuit exists. The possible causes of the diagnostic code are listed:
The signal circuit from the ECM to the solenoid is open.
The return circuit from the solenoid is open. An open in the return circuit may result in an open circuit diagnostic code for all the implement solenoid valves.
The solenoid has failed.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 0354 FMI 05 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:The machine response is listed:Since hydraulic flow to the cylinder is supplied by two control valves, the raise function is disabled. The blade will be able to be lowered.Test Step 1. CHECK THE SOLENOID.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
Disconnect the solenoid with the active diagnostic code from the machine harness.
At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire H713-PK(Pink)) to contact 2 (wire H716-WH(White)).
Observe the status of the CID 0354 FMI 05. Expected
