Circuit Description
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
The seat recline motor is equipped with a potentiometer type position sensor used by the driver seat module to determine the position of the seat back. The motor position sensor is supplied with 5-volt reference and ground circuits from the driver seat module. The position sensor signal circuit is referenced from ground within the driver seat module. The signal voltage monitored by the driver seat module ranges from 0.39-4.58 volts and is determined by the wiper location on the resistor within the motor position sensor. The position sensor circuit voltage level is used by the driver seat module to determine the position of the seat back when storing or recalling memory position settings.
