The RCM continuously monitors the left front impact sensor circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted left front impact sensor
If a fault is detected, the RCM stores DTC B1413:11, B1413:81 or B1413:93 in memory and sends a message to the IPC to illuminate the airbag warning indicator.
