Schematic of the action alarm | |
This diagnostic code is associated with the action alarm. The FMI 03 means that the Advisor has determined that the voltage of the alarm circuit is above normal.
The possible causes of the diagnostic code are listed:
- The alarm has failed.
- The energize circuit of the alarm is shorted to the +battery circuit.
- The Advisor 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 0271 FMI 03 is active before performing this procedure.
Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.
Test Step 1. CHECK THE ENERGIZE CIRCUIT OF THE ALARM FOR A SHORT TO THE +BATTERY CIRCUIT.
- Turn the key start switch and the disconnect switch to the OFF position.
- Disconnect the machine harness connectors from the alarm and the Advisor.
- At the machine harness connector for the Advisor, measure the resistance from contact 54 (wire 410-WH) to all contacts that are used in the machine harness connectors for the Advisor.
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 2.
- NOT OK - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between 54 (410-WH) and the circuit that has a low resistance measurement.
Repair: Repair the machine harness or replace the machine harness.
STOP
Test Step 2. CHECK IF THE DIAGNOSTIC CODE IS STILL ACTIVE.
- Inspect the contacts and clean the contacts of the harness connectors.
- Reconnect all harness connectors.
- Turn the disconnect switch and the key start switch to the ON position.
- Operate the machine.
- Determine if the CID 0271 FMI 03 is active.
Expected Result:
The CID 0271 FMI 03 is active.
Results:
- YES - The CID 0271 FMI 03 is active. The problem has not been corrected. The Advisor may have failed.
Repair: It is unlikely that the Advisor has failed. Exit this procedure and perform this procedure again. If the cause of the diagnostic code is not found, replace the Advisor. See Testing and Adjusting, "Electronic Control Module (ECM) - Replace".
STOP
- NO - The CID 0271 FMI 03 is not active. The problem does not exist at this time.
Repair: 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. Resume normal machine operation.
