Normal Operation and Fault Conditions
The RCM transmits an event notification signal which communicates fuel cutoff status and SRS deployment status to the BCM . This allows the BCM to initiate fuel cut-off in the event of a crash.
The RCM monitors the event notification signal circuit for the following faults:
- Short to voltage
- Short to ground
- Open circuit
If a fault is detected, the RCM stores DTC B11D8:12 or B11D8:14 in memory. The airbag warning indicator will not be illuminated if B11D8:12 or B11D8:14 is set.
