B0092 belongs to the second crash sensor on the left side. Mitsubishi fits it at the left B-pillar and lists it as B-PILLAR SAT SEN LH, adding the J2012 title Left Side Restraints Sensor 2; its index shows only subtype -55, set two seconds after the unit finds that its stored configuration does not fit the vehicle. A pillar position suits an acceleration satellite: Bosch mounts these on stiff members such as sills, seat cross members or B- and C-pillars, and its SMA773 chip measures two axes up to 60 g and talks to the module over a two-wire PSI5 link. GM-built Saabs use the number differently: the 2006 9-5 and the 9-3 store B0092 for a general fault of the passenger presence system, with the airbag system then rated out of order. The airbag lamp is on.

Likely causes

Airbag unit configuration not matching the fitted sensors (Mitsubishi subtype -55)
Loose or corroded plug at the B-pillar sensor after trim or body work
On GM-built Saabs, passenger presence system fault (different meaning)
Internal fault of the B-pillar satellite sensor

Symptoms

  • Airbag warning lamp on
  • Left side impact detection rests on the remaining sensors only
  • Safety note: airbag system; disconnect the battery and keep the wait time before removing pillar trim, work at a specialist workshop
