Circuit Description

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The recline seat motor is equipped with a potentiometer type position sensor used by the memory seat module to determine the seat recline position. The recline motor position sensor is supplied with 5-volt reference and ground circuits from the memory seat module. The position sensor signal circuit is supplied 5-volts through a resistor then monitored within the memory seat module. The signal voltage monitored by the memory seat module ranges from 0.39 - 4.58 volts and is determined by the wiper location on the resistor within the recline motor position sensor. The recline motor position sensor circuit voltage level is used by the memory seat module to determine the seat recline position when storing or recalling memory seat position settings.
