The power liftgate system utilizes its own liftgate control module. This control module contains all the solid state hardware and software used to control the power liftgate system. For specific component information refer to the individual component descriptions later in this article.

Safety is of the utmost concern with the power liftgate system. Software technology has enabled the power liftgate control module to detect resistance to liftgate travel. This allows the power liftgate control module to control liftgate direction anytime an obstruction is detected. In the unlikely event that the power liftgate system develops a fault the power liftgate can still be operated manually, using the electronic liftgate switch.

The power liftgate control module communicates on the Programmable Communication Interface (PCI) Bus Circuit. Therefore, the power liftgate control module can generate and store its own Diagnostic Trouble Codes (DTC's). The CS Body Control Module (BCM) sends and receives messages to the power liftgate control module via the PCI bus circuit. A diagnostic scan tool, such as the DRB III® is used to read and troubleshoot these Diagnostic Trouble Codes. Refer to BODY DIAGNOSTIC PROCEDURES - PACIFICA for a complete list of diagnostic routines.

For a complete wiring schematic of the power liftgate system, refer to SYSTEM WIRING DIAGRAMS . For system operation instructions refer to the owner's manual. Refer to LIFTGATE for additional information on liftgate components such as the prop rods, hinges, door alignment and striker alignment.

The power liftgate system is designed with a number of system inhibitors. These inhibitors are necessary for safety and/or feasibility of the power liftgate system. Refer to POWER LIFTGATE SYSTEM INHIBITORS .
