Power Seat Control Module: Description and Operation

OCCUPANT CLASSIFICATION SENSOR AND ECU






CAUTION: Improper services cause the system to be inoperative. Do not disassemble or tamper with the occupant classification sensor to prevent the serious injury.

The occupant classification sensors are attached to the seat rails and provide the air bag control unit with information on the weight applied to the front passenger seat.

The air bag control unit controls deployment output of the driver's air bag in accordance with the information from the sensor. The air bag control unit controls deployment output of the front passenger's air bag in accordance with the information from the sensor. The front passenger's air bag does not deploy in an impact when the weight applied to the seat is sensed as less than 66 pounds (30 kg).
