B00C2 code meaning
Passenger Seat Occupant Classification Sensor C
What B00C2 means
B00C2 names the third classification input of the passenger seat. No carmaker documents it, and nobody has tied the letter to a known part. Another common sensor type besides load cells is a mat in the cushion. Hyundai extended the cover of the OCS mat in 2006–2011 Accent cars to 15 years with unlimited mileage: the mat should spot child seats and small occupants, and a faulty one could let the bag fire for a child; the lamp then lights with Hyundai's own codes B1447/B1448. Subaru tells technicians for 2014–2016 Forester that spilled drinks, rain through an open window or high humidity reaching the mat can set its occupant detection codes B1760 and B1650. Should C be such a mat, moisture and wear would be the prime suspects. A stored B00C2 lights the airbag lamp.

What to do next
- Note B00C2 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.
