Normal Operation
The Restraints Control Module (RCM) monitors the driver safety belt buckle switch and 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 (Restraints Control Module) will store DTC B0050:11, B0050:12, B0050:13 or B0050:1D in memory and will send a message to the Instrument Panel Cluster (IPC) module to illuminate the air bag warning indicator.





This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- Driver safety belt buckle and pretensioner assembly
- RCM (Restraints Control Module)
