B00C8Passenger Seat Occupant Position Sensor B
- Generic OBD-II code · Body
- How the car detects it
- B00C8 marks the second occupant position sensor of the passenger seat. No carmaker publishes it. A position input does not have to look at the person; it can come from how the load spreads over the seat. In a Honda application filed in 2002, a weight unit under each side of the seat carries four strain gauges in a bridge; comparing the front and rear gauge pairs shows whether the occupant sits on the front edge, and comparing the two sides shows a lean to left or right. FMVSS 208 accepts dynamic suppression for the passenger: the bag must already be suppressed when a 3- or 6-year-old dummy moves its head, neck or torso into a zone in front of the cover, a zone each maker defines for itself. Whether B means such a load-based signal is not documented. B00C8 brings on the airbag lamp.
- What you may notice
- Airbag warning lamp on
- Passenger airbag may be suppressed or released without regard to sitting position
- Safety note: airbag system; disconnect seat sensors only de-energised (ignition off, battery off, wait time), recalibrate after work on the seat, specialist workshop only
- Likely causes
- LikelyPlug or lead to sensor B damaged when the seat was moved or removed
- PossibleStrain gauge bridge or position sensor B faulty, drifting with temperature
- RareSeat frame mounted under tension, so the load split looks implausible
- Repair
- Workshop only · Usually a job for a workshop.Typical cost: €100 – €900
