Connections of the Clutch Solenoid 3 (reverse)This diagnostic code is associated with the Clutch Solenoid 3 (reverse). The FMI 05 diagnostic code means that the ECM has determined that the current is below normal.The possible causes of this diagnostic code are listed below:
The solenoid energizer circuit of the modulating valve is open.
The return circuit of the modulating valve is open.
The solenoid has failed.
The ECM has failed. This situation is unlikely. 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 of the connections in the circuit are clean and that all connections are secure. If a problem with a connection is found, correct the problem and verify that this diagnostic code is active before performing this procedure. Each connector contact should withstand 45 N (10 lb) of pull. Each wire should remain in the connector body. This test checks whether the wire was properly crimped in the contact and whether the contact was properly inserted into the connector. 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 1403 FMI 05 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:When this diagnostic code is active, the ECM will turn off the current to the failed solenoid.Test Step 1. CHECK THE SOLENOID
Turn the disconnect switch and the starter keyswitch to the ON position. Do not start the engine.
Disconnect the solenoid with the active diagnostic code from the transmission harness.
At the connector for the transmission harness for the solenoid, place a jumper wire from contact 1 (wire 754-BU) to contact 2 (wire H803-BU).
Observe the status of the CID 1403 FMI 05 diagnostic code.Expected Result:The CID 1403 FMI 05 diagnostic code remains active. Results:
YES - The diagnostic code remains active. The jumper wire does not affect the diagnostic code. Proceed to Test Step 2.
NO - The diagnostic is no longer active. The solenoid has failed.Repair: The solenoid has failed. Repeat this test step "CHECK THE SOLENOID" in order to verify the solenoid failure. Replace the solenoid. Verify that the new solenoid corrects the problem.STOPTest Step 2. CHECK THE HARNESS FOR AN OPEN
Turn the starter keyswitch and the disconnect switch to the OFF position.
Disconnect the connector of the transmission harness from the ECM.
The jumper wire that was installed in the previous test remains in place.
At the connector of the transmission harness, measure the resistance from signal contact J1-49 (wire 754-GN) to contact J2-35 (wire H803-BU).
At the connector of the transmission harness, measure the resistance from signal contact J1-49 (wire 754-BU) to contact J2-35 (wire H803-BU).Expected Result:Both resistances are less than 5.0 ohms.Results:
OK - Both resistances are less than 5.0 ohms. The transmission harness is correct. Proceed to Test Step 3.
NOT OK - Either resistance is greater
