Power Liftgate (Service Information): Description

A power operated liftgate system is an available option on this vehicle. The power liftgate system includes the following major components, which are described in further detail elsewhere in this service information:

• Chime  - An electronic power liftgate chime tone generator is located on the inside of the left inner D-pillar just below the belt line, where it is concealed behind the interior D-pillar trim.
• D-Pillar Switch  - A power liftgate D-pillar switch (also known as the rear zone switch) is located in a bezel near the back of the left quarter inside trim panel near the D-pillar.
• Exterior Latch Handle Switch  - A power liftgate exterior latch handle switch (also known as the outside handle switch) is integral to the unique power liftgate exterior latch handle.
• Latch  - A unique, electrically actuated power liftgate latch and latch cinching mechanism is installed in place of the latch used on vehicles without the power liftgate system option.
• Overhead Console Switch  - A power liftgate overhead console switch (also known as the front zone switch) is located between the two front reading lamp switches in the overhead console.
• Pinch Sensors  - A power liftgate pinch sensor is located on each side shut face of the liftgate and extends from about the belt line to just below the liftgate opening header. The right side pinch sensor includes an integral thermistor.
• Power Drive Unit  - An electrically operated Power Drive Unit (PDU) is installed on the left side of the liftgate between the liftgate and the liftgate opening trough. It is secured to the same ball studs that are used for the conventional gas-charged hydraulic strut or prop that the PDU replaces.
• Power Liftgate Module  - The Power LiftGate Module (PLGM) (also known as the Power Liftgate/PLG control module) is located on the inside of the left inner D-pillar near the belt line, where it is concealed behind the interior D-pillar trim. Refer to MODULE, POWER LIFTGATE CONTROL (PLGM), DESCRIPTION .
• Thermistor  - A thermistor is internal and integral to the right side pinch sensor.

Hardwired circuitry connects the power liftgate system components to the electrical system of the vehicle. These hardwired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the power liftgate components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin out and location views for the various wire harness connectors, splices and grounds.
