Circuit/System Description
The liftgate control module (LGM) continuously monitors power liftgate operation and calculates its location and direction of travel using 2 Hall
effect sensors that are part of the gear motor assembly. The Hall effect sensors are 5-volt 3-wire sensors and are supplied with a 5-volt power,
ground and signal circuits from the LGM. The Hall effect sensor signal circuits are referenced from voltage within the LGM and pulsed low by the
