Schematic of Action Alarm |
The diagnostic code is recorded when the VIMS module reads the current of the action alarm circuit (410-WH(White)) and the current is below normal. The action alarm may not SOUND or may be weak when this diagnostic code is active.
- CHECK THE ALARM.
- Disconnect the alarm from the machine harness.
- At the machine harness connector for the alarm, place a jumper wire across the two contacts.
Expected Result: The diagnostic code CID 0271 FMI 05 is no longer active.
Results:
- OK - The diagnostic code CID 0271 FMI 05 is no longer active. The alarm is open. Replace the action alarm. Verify that the action alarm is open. The correct resistance for a good alarm is 200 ±100 ohms. STOP.
- NOT OK - The diagnostic code CID 0271 FMI 05 is still active. The action alarm is not causing the fault. Proceed to 2.
- CHECK THE HARNESS.
- Turn the disconnect switch and the key start switch to the OFF position.
- The jumper wire placed in the 1 CHECK THE ALARM test remains connected to the machine harness.
- Disconnect the machine harness from the main module.
- At the machine harness connector for the module, measure the resistance between contact 24 (wire 410-WH(White)) and frame ground.
Expected Result: The resistance is less than 5 ohms.
Results:
- OK - Resistance is less than 5 ohms. The harness circuit resistance is correct. Proceed to 4.
- NOT OK - Resistance is greater than 5 ohms. The harness circuit is open. Proceed to 3.
- CHECK THE HARNESS.
- Turn the disconnect switch and the key start switch to the OFF position.
- The machine harness remains disconnected from the action alarm.
- Remove the jumper wire that was placed in 1 CHECK THE ALARM.
- Check for an open in the action alarm circuit (wire 410-WH(White)). Measure the resistance between the main module harness connector (contact 24) and the action alarm machine harness connector (contact 1).
- Check for an open in the action alarm (return or ground) circuit (wire 201-BK(Black) or 251-BK(Black)). Measure the resistance between the action alarm machine harness connector (contact 2) and the frame ground.
Expected Result: The resistance measurements are less than 5 ohms.
Results:
- OK - Resistance is less than 5 ohms. The machine harness is correct. The fault is intermittent. Proceed to 4.
- NOT OK - Resistance is greater than 5 ohms. The machine harness is not correct. Repair the machine harness or replace the machine harness. STOP.
- CHECK THE MODULE.
- Reconnect the machine harness connector to the main module.
- Reconnect the alarm to the machine harness.
- Turn the disconnect switch and the key start switch to the ON position.
Expected Result: The diagnostic code has not changed. The diagnostic code CID 0271 FMI 05 is still active.
Results:
- YES - Diagnostic code has not changed. Diagnostic code CID 0271 FMI 05 remains active. The main module has failed. Replace the main module. See Testing and Adjusting, "Module - Replace". STOP.
- NO - Diagnostic code is NO longer active. The main module is not causing the diagnostic code. The diagnostic code is intermittent. The probable cause is a poor electrical connection at the harness connectors or a damaged harness. Check the harness for damage. Clean the harness connectors. STOP.
