Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 second row center seatbelt buckle sensor
If a fault is detected, the RCM stores DTC B0054:11, B0054:12, B0054:13 or B0054:1D in memory. A faulted second row center seatbelt buckle sensor or a fault on the second row center seatbelt buckle sensor circuits does not illuminate the airbag warning indicator.
