B0098 code meaning
Right Side Restraints Sensor 3
What B0098 means
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.

Common causes of B0098
- Most likelyOpen or shorted line or poor contact at the right C-pillar plug (subtypes -11/-12/-88/-81)
- PossibleInternal fault of the right C-pillar sensor, e.g. offset or reset error (subtypes -28/-93)
- Less likelyAirbag unit configuration not matching the vehicle (subtype -55)
- Less likelyOn the Saab 9-3, passenger presence system fault (different meaning)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B0098 means

What to do next
- Note B0098 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
