Tests BA: DTC B2855 - Front Crash Sensor Circuit Short to GND/Vbatt Fault

PINPOINT TEST BA: DTC B2855 - FRONT CRASH SENSOR CIRCUIT SHORT TO GND/VBATT FAULT

BA1-BA2:

BA3-BA5:

BA6:

Normal Operation
The restraints control module (RCM) checks the front impact severity sensor circuits for faults. If the RCM detects a short to ground or voltage on any of the front impact severity sensor circuits, it will store diagnostic trouble code (DTC) B2855 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 front impact severity sensor circuit short to ground/voltage fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty front impact severity sensor.
- incorrect sensor mounting.
- a faulted RCM.
