Occupant Detection System
| Item Number | Description |
|---|---|
| 1 | Seat cushion |
| 2 | Pressure switch |
The occupant detection system can only determine if the front passenger seat is occupied or unoccupied. The occupant detection system consists of a pressure switch installed between the foam padding and the cover of the front passenger seat cushion.
The pressure switch incorporates a number of load cells connected in series and embedded in a plastic film. Weight on the pressure sensor increases the resistance of the circuit.
The instrument cluster supplies a reference voltage to the pressure switch and measures the current draw to determine the occupancy status. From the occupancy status, and the status of the front passenger safety belt (received from the restraints control module (RCM) on the high speed controller area network (CAN) bus), the instrument cluster determines the belt minder status.
