Schematic of the action alarm | |
This diagnostic code is associated with the action alarm. The FMI 04 means that the Advisor has determined that the current of the alarm is above normal.
The possible causes of this diagnostic code are listed:
- The energize circuit of the alarm is shorted to ground.
- The alarm has failed.
- 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 04 is active before performing this procedure.
Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.
System Response:
A warning will be displayed on the Advisor. The Advisor will have no control over the alarm circuit.
Test Step 1. CHECK THE ALARM.
- 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 alarm with the active diagnostic code from the machine harness.
Expected Result:
CID 0271 FMI 04 changes to CID 0271 FMI 05 when the alarm is disconnected.
Results:
- YES - CID 0271 FMI 04 changes to CID 0271 FMI 05 when the alarm is disconnected. The circuit is correct.
Repair: The alarm has failed. Repeat this test "CHECK THE ALARM" in order to verify the failure of the alarm. Replace the alarm.
STOP
- NO - CID 0271 FMI 04 remains active. Proceed to Test Step 2.
Test Step 2. CHECK THE ENERGIZE CIRCUIT OF THE ALARM FOR A SHORT TO GROUND.
- Turn the key start switch and the disconnect switch to the OFF position.
- The alarm remains disconnected from the machine harness.
- Disconnect the machine harness connector(s) from the Advisor.
- At the machine harness connector, measure the resistance from the signal 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 3.
- NOT OK - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between 54 (wire 410-WH) and the circuit with the low resistance measurement.
Repair: Repair the machine harness or replace the machine harness.
STOP
Test Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS.
- Inspect the harness connectors 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.
- Check the status of the CID 0271 FMI 04.
Expected Result:
The CID 0271 FMI 04 is active.
Results:
- YES - The CID 0271 FMI 04 is active. The diagnostic code 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 04 is not active. The diagnostic code 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.
