will then signal the liftgate mounted latch assembly to release the liftgate from its primary closed and latched position to the ajar and movable position.
The power liftgate drive unit then takes over to move the liftgate into the full open position.
LIFTGATE IS OPEN
The power liftgate open command can be initiated by either one press of the power liftgate overhead console switch, one press of the power liftgate
D-Pillar switch or two presses of the key fob power liftgate button. The overhead console and D-Pillar switches are hardwired to the power liftgate
control module, where as the key fob signal is sent out on the Controller Area Network (CAN) Data Bus circuit. This signal is detected by the power
liftgate control module. The power liftgate control module then interprets the information to confirm safety requirements are met. The control module
will then signal the power liftgate drive unit to move the liftgate into the closed position. Once the liftgate mounted latch reaches the body mounted
striker assembly, the power latch takes over to cinch the liftgate to the fully closed and latched position.
If an obstacle is encountered during a power open or close cycle, the power liftgate control module will automatically reverse direction of the liftgate to
prevent vehicle damage or personal injury.
Power Liftgate Link Rod - Description
DESCRIPTION
WARNING: Never attempt to operate the power liftgate system when the link rod is removed or disconnected. Always disconnect and isolate
the battery negative cable prior to servicing the link rod or pivots. Damage to the power liftgate system will result if either
direction is not followed.
Vehicles equipped with a power liftgate utilize a link rod (1) assembly. This link rod is located in the left rear of the vehicle and is visible without
removing the D-pillar trim. The link rod attaches to the liftgate pivot bracket (2) at one end and the power liftgate drive unit assembly at the other. The
link rod consists of a steel shaft, equipped with two spherical rod end receptacles at each end. The weight of the liftgate is not supported by the link rod,
the liftgate prop rods are designed to support the liftgate.
The link rod cannot be adjusted or repaired and if inoperative, must be replaced. See: Service and Repair/Power Liftgate Link Rod - Removal.
