B0002Driver Frontal Stage 2 Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- Dual-stage driver airbags hold a second charge that the restraint module fires only in severe crashes or after a short delay, so the cushion fills harder or for longer; a Nissan patent bases that choice on the change in vehicle speed and belt use. B0002 flags a fault in the firing loop of this second stage. Land Rover documents B0002-13 as an open stage 2 circuit on the Evoque, which also appeared after a module replacement had loaded older software (SSM 74577). Mercedes-Benz, Mitsubishi and FCA list it as the driver squib or module 2, GM as stage 2 of the steering wheel module. Because both stages share connector and clock spring, B0002 often comes together with B0001; alone it points to the stage 2 lead or squib. Adaptive inflation is lost and the airbag lamp is on.
