B00CAPassenger Seat Occupant Position Sensor D
- Generic OBD-II code · Body
- How the car detects it
- B00CA is position input D, the fourth for the passenger seat. Its use is not documented by any carmaker. Optical sensing is one way to fill such a slot: a patent family of Automotive Technologies International, going back to 1995, places imagers with infrared lighting at the A-pillar, in the headliner or on top of the dashboard, two arrays spaced apart for depth, and calls an occupant out of position once head or chest come within about 5 inches of the airbag door. Pattern recognition separates a rear-facing child seat from a person, and the authors judge ultrasound with roughly 10 ms per update as too slow for tracking during a crash. For the passenger, FMVSS 208 permits dynamic suppression and prescribes no method. With B00CA stored, that view is lost and the airbag warning shows.
