Normal Operation and Fault Conditions
The RCM continuously monitors the second row left seatbelt buckle switch circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Current out of range
- Faulted third row center seatbelt buckle sensor
If a fault is detected, the RCM stores DTC B0057:11, B0057:12, B0057:13 or B0057:1D in memory. A faulted third row center seatbelt buckle sensor or a fault on the second row center seatbelt buckle sensor circuits does not illuminate the airbag warning indicator.
