Mazda CX-5 Service & Repair Manual: Seat Track Position Sensor [Two Step Deployment Control System]

Purpose

• The seat track position sensor detects the front and back positions of the driver seat.

Function

• The seat track position sensor converts the seat position into an electrical signal and sends it to the SAS control module.

Construction

• The seat track position sensor consists of a hall element (semi-conductor) and a magnet. The sensor converts the effect of the magnetic flux (produced by the magnet) on the hall element, into an electrical signal.

• The seat track position sensor installed on the driver-side seat rail.

Operation

• If the driver’s seat is slid forward, the seat track position sensor will separate from the metal plate installed to the seat slider.

• When this occurs the magnetic flux of the sensor changes and that change is sent as an electrical signal to the SAS control module.

• The SAS control module receives this signal and determines that the driver’s seat has been moved to a forward position.

Fail-safe

• Function not equipped.
