Sensor, Seat Weight: Description: Description
The seat weight sensors are strain gauge-type units. The electronic elements of the sensor are encased within the sensor body (5) and the sensor body is located within a stamped metal cage (3). Four sensors are used in the Occupant Classification System (OCS). The sensors are located below the seat cushion between the seat adjuster track and the seat track riser at each corner of the passenger side front seat.
A threaded mounting stud (2) on each sensor body is secured by a nut to the seat track riser, and two nuts secure each sensor mounting flange (1) to two studs integral to the front and rear of the inboard and outboard passenger side lower seat adjuster tracks. A molded connector receptacle (4) integral to each sensor body is oriented towards the center of the seat and is connected to the vehicle electrical system through a dedicated connector and take out of the passenger seat wire harness beneath the seat cushion.
The seat weight sensors cannot be adjusted or repaired and, if ineffective or damaged, the entire sensor must be replaced.
