B00CBPassenger Seat Occupant Position Sensor E
- Generic OBD-II code · Body
- How the car detects it
- B00CB is the fifth and last passenger seat occupant position sensor. No carmaker publishes it. Position alone is not always enough; an early patent of Automotive Technologies International, first filed in 1992, also wants the speed at which the occupant approaches the bag. It uses ultrasound bursts near 50 kHz, taking distance from the echo time and speed from the Doppler shift, or modulated infrared and radar, mounted in the headliner, on the mirror or on the airbag cover. In a 30 mph barrier crash it allows only about 8 ms of sensing for someone 9 inches away but 57 ms at 24 inches. FMVSS 208 lets the maker define the suppression zone that such sensors watch. Whether E denotes a velocity or a further distance sensor is not documented. B00CB lights the airbag lamp.
