Connections of the transmission solenoidThis diagnostic code is associated with the transmission solenoid. The FMI 06 means that the ECM has determined that there is a short to ground.The possible causes of this diagnostic code are listed:
The energize circuit of the solenoid is shorted to ground.
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 0133 FMI 06 is active before performing this procedure.Note: Use a digital multimeter for the measurements in this procedure.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 FMI 06 changes to FMI 05 after the solenoid is disconnected.Results:
YES - The FMI 06 changes to FMI 05 after the solenoid is disconnected. The circuit is correct.Repair: The solenoid has failed. Replace the solenoid. Verify that the new solenoid has corrected the problem.STOP
NO - The FMI 06 remains active. Proceed to Test Step 2.Test Step 2. CHECK THE ENERGIZE CIRCUIT OF THE SOLENOID FOR A SHORT TO GROUND.
Turn the key start switch and the disconnect switch to the OFF position.
The solenoid remains disconnected from the machine harness.
Disconnect the machine harness connector from the ECM.
At the machine harness connector, measure the resistance from the signal contact J1-34 (wire H416-GN) to all contacts that are used in the machine harness connectors for the ECM. Expected Result:Each resistance measurement is greater than 5000 ohms.Results:
OK - Each resistance measurement is greater than 5000 ohms. The machine harness is correct. Proceed to Test Step 3.
NOT OK - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between 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 3. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Perform the following:
Inspect the harness connectors.
Clean the contacts of the harness connectors.
Inspect the insulation of the wires for damage that is caused by excessive heat, battery acid, or chafing.
Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit.
Reconnect all harness connectors in order to make sure that the connectors are fully seated. Also, make sure that the clips for each connector are fastened completely.
Turn the disconnect switch and the key start switch to the ON position.
Operate the machine.
Determine if the diagnostic code is active.Expected Result:The diagnostic code is active.Results:
YES - The diagnostic code is active. The problem has not been corrected.Repair: Check the circuit again. Perform a "Wiggle Test" on
