Connections of the transmission solenoidThis diagnostic code is associated with the transmission solenoid. The FMI 04 means that ECM has detected that either an open in the circuit or a short to ground in the return circuit exists.The possible causes are listed:
The return circuit of the solenoid is shorted to ground.
The energize circuit of the solenoid is open.
The return circuit of the solenoid is open.
The solenoid has failed.
The ECM has failed. The failure of the ECM 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 1933 FMI 04 is active before performing this procedure.Note: Use a digital multimeter for the measurements in this procedure.Test Step 1. CHECK THE RETURN CIRCUIT OF THE SOLENOID FOR A SHORT TO GROUND.
Turn the disconnect switch and the key start switch to the OFF position.
Disconnect the solenoid from the machine harness.
Disconnect the machine harness at the ECM.
At the harness connector for the ECM, measure the resistance from the signal contact J1-34 (wire H416-GN) to all contacts that are used in the machine harness connector.Expected Result:Each resistance measurement is greater than 5000 ohms.Results:
YES - Each resistance measurement is greater than 5000 ohms. The machine harness is correct. Proceed to Test Step 2.
NO - Each resistance measurement is NOT greater than 5000 ohms. There is a short in the machine harness between signal contact J1-34 (wire H416-GN) and the circuit with the low resistance measurement.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 2. CHECK THE HARNESS FOR AN OPEN.
The key start switch and the disconnect switch remain in the OFF position.
The machine harness remains disconnected from the ECM.
The solenoid remains disconnected from the machine harness.
At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire H416-GN) to contact 2 (wire 200-BK).Expected Result:The resistance should be less than 5.0 ohms.Results:
OK - The resistance is less than 5.0 ohms. The machine harness is correct. Proceed to Test Step 3.
NOT OK - The resistance is greater than 5000 ohms. The resistance measurement is not correct. There is an open circuit in the machine harness.Repair: The open is in the signal wire (H416-GN) or the return wire (200-BK) of the machine harness. Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK THE SOLENOID.
Remove the jumper wire from the previous Test Step.
Reconnect the machine harness to the ECM.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
The solenoid remains disconnected from the machine harness.
At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire H416-GN) to contact 2 (wire 200-BK).
Observe the status of the diagnostic code.Expected Result:The diagnostic code is active. The diagnostic code changes from
