B0050:11, B0050:12, B0050:13 and B0050:1D: Notes
Refer to SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.
Normal Operation and Fault Conditions
The RCM monitors the driver seatbelt buckle switch circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Current out of range
- Faulted driver seatbelt 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 IPC to illuminate the airbag warning indicator.
