Circuit/System Description

For an overview of the component/system, refer to: Liftgate Description and Operation

Circuit	Description
12 V Reference	Regulated voltage supplied by the control module.
Liftgate Position Sensor 1 Signal Circuit	The control module input circuit has an internal resistance connected to 12 V.
Liftgate Position Sensor 2 Signal Circuit	The control module input circuit has an internal resistance connected to 12 V.
Low Reference	Grounded through the control module.

Component	Description
M17 Liftgate Motor Assembly	The motor M17 is a bidirectional DC motor that moves the component: Power Liftgate (TB5) The assembly also contains a 4-wire hall effect current sensor. When the sensor measures increased electrical current, the control module can detect that the component has reached an endstop.
K39 Liftgate Control Module	The control module K39 controls the liftgate motor function depending on inputs from a variety of sensors, switches and serial data information from other control modules.
