Overhead Console Liftgate Switch
OVERHEAD CONSOLE LIFTGATE SWITCHDESCRIPTION
NOTE: The overhead console shown contains a combination power liftgate/power sunroof switch. Vehicles equipped with the power liftgate and no sunroof contain a single power liftgate switch only.
The power liftgate switch (3) is mounted in the overhead console assembly (1) between the reading lamps (2). The switch is snapped into mounting slots in the overhead console assembly. The momentary, push button-type power liftgate switch, provides a hardwired signal to the Power Liftgate Control Module. If the switch is inoperative or damaged the power lift-gate switch assembly must be replaced.
OPERATION
Battery voltage is supplied to the power liftgate system through a fuse, located in the Integrated Power Module (IPM) assembly. When the power liftgate switch is pushed, a hardwired signal is sent to the Power Liftgate Control Module. The power liftgate control module then interprets the information to confirm safety requirements are met before applying power to the power liftgate drive unit to start a power cycle.
During a power liftgate open or close cycle, if the power liftgate control module detects sufficient resistance to lift-gate travel, such as an obstruction in the liftgate's path. The control module will immediately stop liftgate movement and reverse the direction of travel to the full open or closed position.
