B0098 belongs to the third right-side crash sensor. In Mitsubishi's airbag index it is the C-PILLAR SAT SEN RH, given with the J2012 wording Right Side Restraints Sensor 3. The full set of nine subtypes applies, each set two seconds after detection with the ignition on; beside the usual short to ground (-11), configuration mismatch (-55) and lost communication (-81), the list covers a short to supply (-12), an open line (-88), an offset error (-28) and a reset fault (-93). A sensor this far back sees impacts on the rear door and rear seat area early. Continental's gSAT reports acceleration from rigid structure for such tasks. FCA uses its own code B2765 for the right C-pillar sensor of the Ram 1500, while the Saab 9-3 airbag module uses B0098 to flag that its passenger presence system has failed in general. The airbag lamp lights.

Likely causes

Open or shorted line or poor contact at the right C-pillar plug (subtypes -11/-12/-88/-81)
Internal fault of the right C-pillar sensor, e.g. offset or reset error (subtypes -28/-93)
Airbag unit configuration not matching the vehicle (subtype -55)
On the Saab 9-3, passenger presence system fault (different meaning)

Symptoms

  • Airbag warning lamp on
  • Right side impact sensing at the rear door is degraded
  • Safety note: airbag system; disconnect the battery and keep the wait time before work at the rear pillar, specialist workshop only
