Schematic For The Alarm (Action)

This diagnostic code is recorded when the Main Display Module reads the voltage of circuit for the Action Alarm as above normal or the voltage as shorted to +Battery. As a result of this diagnostic fault condition, the Action Alarm will sound continuously.

1. Check The Alarm Circuit.

   1. Turn the ECS to the OFF/RESET position.

   2. Check for loose terminal connections or corroded terminal connections to the Action Alarm.

   3. Clean corroded terminals and tighten loose connections. Do Not disconnect the harness from the Caterpillar Monitoring System.

   4. Turn the ECS switch to the COOLDOWN/STOP position.

   5. Listen for the sounding of the Action Alarm.

      Expected Result: The alarm should sound.

      Results:

      • OK: The alarm sounds. There is a short between the circuit for the Action Alarm and +battery in the engine harness.

      • Not OK: The alarm does not sound. The Main Display Module has a problem. Replace the Main Display Module of the Caterpillar Monitoring System. For more information about this subject, see Testing And Adjusting, "Module - Replace".
