PINPOINT TEST J : B0052:11, B0052:12, B0052:13 and B0052:1D: Notes
Diagnostic Overview
B0052:11, B0052:12, B0052:13 and B0052:1D
Refer to SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.
The RCM monitors the passenger safety belt buckle switch circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Current out of range
- Faulted passenger safety belt buckle switch
If a fault is detected, the RCM stores DTC B0052:11, B0052:12, B0052:13 or B0052:1D in memory and sends a message to the IPC to illuminate the airbag warning indicator.
