Engine cooling fan solenoid connections
This diagnostic code is associated with the engine hydraulic cooling fan. The FMI 05 means that the ECM has determined that the current for the solenoid is below normal. An open may exist in the circuit for the solenoid. Some possible causes of this diagnostic code are listed below:
The energize circuit of the solenoid is open.
The return circuit of the solenoid is open.
The solenoid has failed.
The ECM has failed. This is unlikely. System Response:When the CID 0291 FMI 05 diagnostic code is active, the machine response can be:
The engine cooling fan will operate at the minimum speed or will not operate.
The engine coolant temperature may increase.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 0291 FMI 05 is active before performing this procedure.Test Step 1. CHECK THE SOLENOID
Disconnect the solenoid from the machine harness.
At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire J816-GN(Green)) to contact 2 (wire K927-BU(Blue)).
Turn the disconnect switch and the
