B0011Passenger Frontal Stage 2 Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- B0011 is the passenger counterpart of B0002: it concerns the second inflator stage of the dashboard airbag, which the module adds in severe crashes or fires with a delay. Mercedes-Benz logs B001113 for an open stage 2 squib of the front passenger airbag, and Mitsubishi lists B0011 as passenger airbag module 2. Stage 1 of the same bag has its own code B0010, a third element B0012. Since both stages leave the module through one connector, a code for stage 2 alone usually means a fault in the stage 2 pins, lead or squib rather than a general connector problem. Older GM modules (Saab 9-3 up to 2011) put passenger stage 2 faults under B0012 to B0014 instead. The airbag lamp is on and adaptive inflation for the passenger is lost.
