B00BBDriver Seat Occupant Position Sensor E
- Generic OBD-II code · Body
- How the car detects it
- B00BB is the fifth and last driver seat occupant position sensor in the J2012 block. No carmaker publishes this code. Position need not be measured on the body itself: an ATI patent family dating back to 1992 infers it from the seat, using a potentiometer or other track sensor, a recline angle sensor and belt spool-out from a shaft encoder in the retractor, and may suppress or depower the bag when the seat is fully forward. FMVSS 208 leaves both the suppression zone and the choice of sensors to the maker. Because J2012 already has separate codes for the indirect seat data, B00B5 for the track and B00B6 for the recline, the letter E probably denotes a further direct sensor, though no source confirms it. When B00BB is stored, the airbag lamp is lit.
