B00BADriver Seat Occupant Position Sensor D
- Generic OBD-II code · Body
- How the car detects it
- B00BA covers position input D, the fourth of the driver seat sensors. Its use by a carmaker is not documented publicly. Early out-of-position concepts mixed several sensor kinds: a 1989 Automotive Systems Laboratory patent uses a pyroelectric detector for presence, ultrasound for the distance to wheel and dashboard and a pressure transducer under the occupant for weight, recommends redundant sensors of each kind against false readings, warns the occupant with a lamp and fires a multi-cartridge driver inflator step by step to match size and position. A fourth slot thus suits a redundant sensor or one working on another principle, but no maker confirms what D stands for. B00BA indicates a fault in that input; the warning lamp for the airbags lights and position-based staging is limited.
- What you may notice
