Connections of the Forward Solenoid Clutch 2This diagnostic code is associated with the Forward Solenoid Clutch 2. The FMI 06 means that the ECM has detected that the current for the solenoid circuit is above normal. The following conditions could cause this diagnostic code to be activated:
The energize circuit of the solenoid is shorted to a ground source.
The solenoid has failed.
The ECM has failed. The failure of the ECM is unlikely. System Response:Forward gear will be disabled.Note: Before performing this procedure, inspect the harness connectors that are involved in the circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit meet the following requirements: clean, secure and good condition. If a problem with a connection is found, correct the problem and verify that this diagnostic code is active before performing this procedure. 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.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 active CID 1402 FMI 06 diagnostic code changes to a CID 1402 FMI 05 diagnostic code when the solenoid is disconnected.Results:
YES - The active CID 1402 FMI 06 diagnostic code changes to a CID 1402 FMI 05 diagnostic code when the solenoid is disconnected. The solenoid circuit
