The Restraints Control Module (RCM) monitors the driver safety belt buckle switch circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Current out of range
- Faulted driver safety belt buckle switch
If a fault is detected, the RCM stores DTC B0050:11, B0050:12, B0050:13 or B0050:1D in memory and sends a message to the Instrument Panel Cluster (IPC) to illuminate the airbag warning indicator.
