Schematic Of The Direction Clutch Solenoid 2Service Notes: Ensure that the CID 0642 FMI 03 fault is on hold. Ensure that the fault is ACTIVE. Use table 1 to determine the solenoids that are energized in the various positions of the shift lever. An easy check of the solenoids can be done by placing a steel washer next to the solenoid that should be energized. The solenoid becomes magnetic when the solenoid is energized. The washer should be attracted to the energized solenoid.

Reverse 3     1 and 4    A CID 0642 FMI 03 fault is recorded when the ECM senses a short to + battery in the solenoid circuit.
CHECK FOR A SHORT TO +BATTERY.
Disconnect the machine harness connector from the ECM.
At the machine harness connector, check for continuity from solenoid output J1-4 to +battery (J1-1). Turn ON the various +battery circuits of the machine to check for shorts from these circuits to wire 752-YL. Headlights and the heater are examples of + battery circuits.Expected Result: There is no continuity.Results:
YES - There is NO continuity. The solenoid harness is not shorted to +battery. Go to Step 2.
NO - There is continuity. The solenoid harness is shorted to +battery. Repair the machine harness or replace the machine harness.
CHECK FOR A SHORT TO OTHER SOLENOID OUTPUTS.
Check for continuity from the faulty solenoid output to the other solenoid outputs. The other solenoid outputs are listed here: Solenoid 1 (J1-10), Solenoid 3 (J1-17), Solenoid 4 (J1-11), Solenoid 5 (J2-7) and Solenoid 6 (J2-1)Expected Result: There is continuity to one of the circuits.Results:
YES - There is continuity. The solenoid harness is shorted. Repair the machine harness or replace the machine harness.
NO - There is NOT continuity. The circuitry of the solenoid harness is correct.
INSPECT THE CONNECTOR CONTACTS AND RECHECK FOR A FAULT.
Inspect the harness connector contacts. Repair any faulty contacts.
Reconnect the harness connector to the ECM. Check the ECM for an ACTIVE CID 0642 FMI 03 fault. Expected Result: The fault is not present.Results:
YES - The fault is not present. The initial fault was probably caused by a poor electrical connection or a short at one of the harness connectors that was disconnected and reconnected. Resume normal machine operation and watch for a recurrence of the fault.
NO - The fault is still present. It is unlikely that the ECM is faulty. Exit this procedure and perform this CID FMI procedure again. If the cause is not found, replace
