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 liftgate 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.
