B00B8Driver Seat Occupant Position Sensor B
- Generic OBD-II code · Body
- How the car detects it
- B00B8 names the second occupant position sensor at the driver seat. The code is not published by any carmaker, and the letter assignment is the maker's choice. Instead of looking down from the roof, a position sensor can sit at the airbag cover itself: a patent first filed in 1998 by Automotive Systems Laboratory, now held by Joyson, puts an active infrared, ultrasonic or electric field sensor in or near the inflator door, keeps the bag disabled while a large body part is in the at-risk zone and cites NHTSA findings that injuries drop if the bag stays off for occupants roughly 4 to 10 inches from the door. FMVSS 208 accepts such dynamic suppression for the driver bag. A stored B00B8 means this input has failed; the airbag lamp lights.
