What it means

B0002 is a generic body code relating to the driver frontal airbag, stage 2 deployment control circuit. The restraint control module has detected a fault in the circuit or squib that controls the second stage of the driver airbag inflator. The airbag warning light will normally be on and the system may be disabled.

Symptoms

Airbag or SRS warning light on the instrument panel
Driver airbag may not deploy, or may not deploy fully, in a crash
Fault stored in the restraint control module, sometimes with other airbag codes
Failed MOT or inspection because of the SRS warning light
Intermittent warning light that appears after turning the steering wheel or hitting bumps

Possible causes

Faulty clockspring (spiral cable) in the steering column breaking the circuit to the driver airbaglikely
Damaged, corroded or loose connector at the base of the steering wheel or under the driver airbaglikely
Open circuit, high resistance or short in the wiring between the restraint control module and the airbagpossible
Faulty driver airbag module or stage 2 squibpossible
Fault in the restraint control module itselfrare
Previous crash damage or incorrect repair, including a mismatched or non-approved replacement partrare

How to diagnose

Read all stored codes and freeze frame or status data from the restraint control module, noting whether the fault is current or historic, and check for related airbag codes
Look up the manufacturer's procedure for the vehicle, as safe handling and disarming steps differ between models
Visually inspect the connectors and wiring around the steering column, steering wheel and under the seat for damage, corrosion or poor seating
Check whether the fault changes when the steering wheel is turned lock to lock or the wiring is gently moved, which points towards the clockspring
Disconnect the battery and wait the time specified by the manufacturer before touching any airbag component, and never probe airbag circuits with a standard test lamp or meter not approved for SRS use
Measure circuit resistance and check for shorts to ground or voltage only using the manufacturer's specified method and values
Check the vehicle history for previous accident repairs or airbag component replacement
After repair, clear the codes and confirm the SRS light goes out and does not return

How to fix

Replace the clockspring if it is faulty or open circuit
Repair or replace damaged wiring and clean or replace corroded or damaged connectors
Replace the driver airbag module if it is found faulty, using the correct part for the model
Replace the restraint control module if it is confirmed faulty, and carry out any required coding or setup for the vehicle
Correct any incorrect previous repair and fit the right components for the vehicle

Can I keep driving?

High severity

The driver airbag may not work properly in a crash, so the car should be repaired promptly and driven only when necessary until it is. Do not delay the repair, and have airbag work carried out by a competent technician because of the risk of accidental deployment.
