Forward clutch solenoid connectionsThis diagnostic code is associated with the forward clutch solenoid. The FMI 06 means that the ECM has determined that the current for the solenoid circuit is above normal.The possible causes of this diagnostic code are listed:
The energize circuit of the solenoid is shorted to ground.
The solenoid has failed.
The ECM has failed. This 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 1402 FMI 06 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:When this code is active, the implement lockout solenoid is deactivated (LOCKED) unless the limp home mode is selected. All implement functions are disabled. Test Step 1. CHECK THE SOLENOID
Turn the disconnect switch and the key start switch to the ON position. DO NOT start the engine.
Observe the status of the diagnostic code.
Disconnect the solenoid with the active diagnostic code from the machine harness.Expected Result:The CID 1402 FMI 06 code changes to CID 1402 FMI 05 code when the solenoid is disconnected. Results:
YES - The 1402 FMI 06 code changes to CID 1402 FMI 05 code when the solenoid is disconnected. The circuit is correct. Repair: The solenoid has failed. Repeat this test "CHECK THE SOLENOID"
