B0034Right Side Deployment Stage 2 Control

  • Generic OBD-II code · Body
How the car detects it
B0034 is absent from the J2012 lists, which skip from B0033 to B0038 in the second-row block, and no carmaker or bulletin documents it publicly; the code cannot be traced to a real vehicle. The title describes a second firing stage for the right side airbag. Such bags are rare: Ford's far-side impact patent treats thorax, pelvis and head bags as single-setting because of their size, while Autoliv covers chest and pelvis with a two-chamber bag, not with two firing stages. Right front side airbags carry the J2012 code B0028; Mitsubishi, for example, checks that loop for 2 seconds before storing a fault. If B0034 is read, the module and text shown by the scan tool are what count. Airbag lamp on.
