Ensure that the diagnostic code is on hold. Ensure that the diagnostic code is active.FMI 03 is recorded when the transmission electronic control module senses a short to the battery in the relay's circuit.Note: The following procedure may cause additional faults. Ignore the additional faults. Clear the additional faults after FMI 03 has been cleared.FMI 03 is present. The parking brake is on. The parking brake alarm is sounding regardless of the state of the transmission. Contact 38 could be the problem.
Check the relay.
Turn the key start switch to the OFF position.
Remove the parking brake relay.
Turn the key start switch to the ON position.
Measure the voltage from contact 2 to contact 1.Note: The transmission electronic control module will log an open circuit diagnostic code. Clear this fault after FMI 03 has been cleared.The results of the preceding procedure are in the following list:
The measured voltage is approximately 5 VDC. The relay is faulty. Replace the relay.
The measured voltage is approximately battery voltage. Proceed to 2.
Check the harness.
Turn the key start switch to the OFF position.
Disconnect the machine harness from the control module.
Turn the key start switch to the ON position.
Measure the voltage from contact 2 to contact 38.The results of the preceding procedure are in the following list:
The measured voltage is approximately battery voltage. There is a short to the battery. The short is in the machine harness. Repair the harness or replace the harness.
The measured voltage is approximately 0 VDC. The fault is not isolated. Proceed to 4.a.
Verify that the diagnostic code is present.
Turn the key start switch to the OFF position.
Inspect the connectors and inspect the contacts.
Connect the machine harness to the control module.
Install the relay.
Turn the key start switch to the ON position.
Enter the service mode.Reference: System Operation, "Diagnostic Operation".
Operate the machine.
Check the diagnostic indicator. Note the active faults.The results of the preceding procedure are in the following list:
The fault is active. The fault has not been corrected. The transmission electronic control module may be faulty. Proceed to 4.
The fault is not active. The fault was caused by a poor electrical connection. Clear the fault. Refer to System Operation, "Diagnostic Operation".
Verify that the transmission electronic control module is faulty.
Verify that the key start switch is in the ON position.
Verify that the fault is present. Verify that the fault is active.
Turn the key start switch to the OFF position.
Turn the key start switch to the ON position.
Verify that the fault is present. Verify that the fault is active.The results of the preceding procedure are in the following list:
The fault is present and the fault is active. The transmission electronic control module is faulty. Replace the transmission electronic control module. Refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace".
The fault is not present. Clear the fault. Refer to System Operation, "Diagnostic Operation".
