Seat Position Sensor (USA/Can Only)
The seat position sensor can be used to classify whether a small or large person sitting in the seat. There are two seat position sensors in the vehicle - one under the driver's seat and one under the front passenger seat. The seat position sensors are directly connected to the Supplemental Restraint System Module (SRS).
The seat position sensors comprise a Hall sensor that changes current strength based on the position of the seat. The seat position sensor has two classifications - small person or large person. Small person indicates that the seat is approx. 10 cm (4 in) or less from the front-most seat position. All other positions are classified as large person.
For collision purposes, this information is used to optimize the function of adaptive belt force limitation and the front passenger airbag.
