B153E CHEVROLET Description

 

The liftgate control module continuously monitors power liftgate operation and calculates its location and direction of travel using 2 Hall effect sensors that are part of the liftgate motor. The Hall effect sensors are 12 V 3-wire sensors and are supplied with a 12 V reference, ground and signal circuits from the liftgate control module. The Hall effect sensor signal circuits are referenced from voltage within the liftgate control module and pulsed low by the Hall effect sensors.
