Number 6 Clutch Solenoid Modulating Valve SchematicCID 0636 FMI 06 service code is recorded when the power train electronic control module (ECM) reads the current of the solenoid circuit as above normal (short to ground). Note: Ensure that the service code CID 0636 FMI 06 for the solenoid is active. Before performing this procedure, refer to table 1 in order to determine the connector contact number and the wire number that corresponds to the failed circuit.

Number 6 Clutch Solenoid Modulating Valve (First Speed)     J2-2     901-WH    
( 1 ) Connector contact number of the power train ECM.Note: All of the solenoid return lines are joined and connect to contacts J1-7 and J2-3 (wire 975-WH).Note: The approximate coil resistance of the clutch solenoid modulating valves is 5 to 15 Ohms.Note: Access to the clutch solenoid modulating valve may require removal of the left rear platform support bracket. Replacement of the clutch solenoid modulating valve may require removal of the cab.
Check the resistance of the solenoid.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness from the suspected solenoid.
At the clutch solenoid modulating valve, measure the resistance between the two contacts of the solenoid connector.Expected Result: The resistance should be between 5 - 15 Ohms.Results:
OK - The solenoid resistance is correct. Proceed to Step 2.
NOT OK - The solenoid has failed. Replace the solenoid. STOP.
Check the solenoid for a short to ground.The disconnect switch and the key start switch remain in the OFF position. The solenoid remains disconnected from the machine harness.
Measure the resistance from each solenoid contact to frame ground.Expected Result: Each resistance should be greater than 5000 Ohms.Results:
OK - The solenoid and the solenoid harness are correct. The fault is in the machine harness. Proceed to Step 3.
NOT OK - The solenoid has failed. Replace the solenoid. STOP.
Check the machine harness for a short to ground.The machine harness remains disconnected from the solenoid.
The disconnect switch and the key start switch remain in the OFF position.
Disconnect the machine harness connectors J1 and J2 from the power train ECM.
At machine harness connector J1 or J2, measure the resistance from the solenoid signal contact (refer to table 1) to all possible sources of ground. The following contacts are possible ground sources: J1-2, J1-5, J1-7, J1-15, J1-16, J2-3 and frame ground.Expected Result: Each resistance should be greater than 5000 Ohms.Results:
OK - The machine harness is correct. Proceed to Step 4.
NOT OK - There is a short in the machine harness. The short is between the wire for the solenoid signal (refer to table 1) and the circuit with the low resistance measurement. Repair the machine harness or replace the machine harness. STOP.
Check if the fault is still present.
Inspect the contacts and clean the contacts of the harness connectors.
Reconnect all harness connectors.
Turn the disconnect switch and the key start switch to the ON position.
Operate the machine.
Stop the machine
