Test G: DTC B1050 - Passenger Side Crash Sensor Short to Gnd/VBatt Fault
2007 Ford Focus L4-2.3L VIN ZSECTION Test G: DTC B1050 - Passenger Side Crash Sensor Short to Gnd/VBatt Fault
PINPOINT TEST G: DTC B1050 - PASSENGER SIDE CRASH SENSOR SHORT TO GND/VBATT FAULT
Normal Operation
The restraints control module (RCM) checks the passenger side impact sensor circuits for faults. If the RCM detects a short to ground or voltage on the passenger side impact sensor circuits, it will store diagnostic trouble code (DTC) B1050 in memory and illuminate the air bag indicator.
Fault Conditions
The RCM monitors for the following fault conditions:
- Circuit short to voltage
- Circuit short to ground
Possible Causes
A passenger side impact sensor short to ground/voltage fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulted RCM.
