Normal Operation and Fault Conditions
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The RCM continuously monitors the third row right seatbelt buckle sensor circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Current out of range
- Faulted third row right seatbelt buckle sensor
If a fault is detected, the RCM stores DTC B140F:11, B140F:12, B140F:13 or B140F:1D in memory. A faulted third row right seatbelt buckle sensor or a fault on the third row right seatbelt buckle sensor circuits does not illuminate the airbag warning indicator.
