Pinpoint Test A : B140D:11, B140D:12, B140D:13 And B140D:1D: Notes
Diagnostic Overview
Refer to SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.
Normal Operation and Fault Conditions
On vehicles equipped with inflatable seatbelts, the RCM monitors the second row right seatbelt buckle switch and circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Current out of range
- Faulted second row right seatbelt buckle switch
If a fault is detected, the RCM stores DTC B140D:11, B140D:12, B140D:13 or B140D:1D in memory and sends a message to the IPC to illuminate the airbag warning indicator.
