B0002: Driver Frontal Stage 2 Deployment Control
Can you still drive? The vehicle will operate, but this is a critical safety defect — the driver airbag may not provide full protection in severe crashes. Repair immediately.
What Does B0002 Mean?
Code B0002 indicates a fault in the driver-side frontal airbag stage 2 deployment circuit. Stage 2 is a secondary inflator that provides additional cushioning during severe frontal collisions. A failure here means the airbag may partially deploy but not provide full protection in a high-severity impact.
