Connections of the Clutch Solenoid 6 (speed clutch 1)
This diagnostic code is associated with the Clutch Solenoid 6 (speed clutch 1). The FMI 03 diagnostic code means that the ECM has determined that the voltage is above normal.The possible causes of the diagnostic code are listed below:
The solenoid energizer circuit of the modulating valve is shorted to the +battery circuit.
The ECM has failed. This 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 1406 FMI 03 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.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. System Response:When this diagnostic code is active, the ECM will turn off the current to the failed solenoid.Test Step 1. CHECK THE WIRING HARNESS AND CONNECTORS
Inspect the harness connectors. Clean the contacts of the harness connectors. Check the wiring for signs of damage that are related to excessive heat, exposure to acid, signs of melting or wear that is caused by rubbing.
Remove the connector at the ECM. Check for the presence of water inside the connector or around the connector.
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 completely fastened.
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 Expected Result:The diagnostic code is no longer active.Results:
YES - The diagnostic code is not active. The initial diagnostic code was probably caused by a poor electrical connection or a short at one of the harness connectors that was disconnected and reconnected. The problem does not exist at this time. Resume normal machine operation.STOP
NO - The diagnostic code is active. The problem has not been corrected. Proceed to Test Step 2.Test Step 2. CHECK THE SOLENOID WIRE FOR VOLTAGE .The disconnect switch and the key start switch remain in the OFF position.
At the J1 connector for the ECM, use a wire removal tool to remove wire 901-WH(White) from contact J1-62.
Reconnect the machine harness J1 and J2 connectors to the ECM.
Turn the disconnect switch and the key start switch to the ON position.
Use a multimeter in order to check the voltage between wire 901-WH(White)
