PINPOINT TEST BJ : B140C:11, B140C:12, B140C:13 and B140C:1A: Notes
Diagnostic Overview
B140C:11, B140C:12, B140C:13 and B140C:1A
Refer to SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.
On vehicles equipped with inflatable safety belts, the RCM monitors the second row left safety belt buckle switch circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Current out of range
- Faulted second row left safety belt buckle switch
If a fault is detected, the RCM stores DTC B140C:11, B140C:12, B140C:13 or B140C:1D in memory and sends a message to the IPC to illuminate the airbag warning indicator.
