Each power sliding door is equipped with a Power Sliding Door Control Module (PSDM). The PSDM is mounted directly to the inboard side of the power sliding door drive assembly with two retaining screws. The drive assembly is mounted to the body near the bottom of the sliding door in the track cavity with the use of five retaining nuts. The wire harness and chain link track and the power sliding door drive assembly are visible with the door open in the lower door sill area.

Software technology has enabled the PSDM to detect resistance to door travel. This allows the power sliding door to stop and reverse direction any time an obstruction is felt or any of the command switches are operated. Battery voltage is supplied to the power sliding door system through a fuse located in the Power Distribution Center (PDC). The power sliding door lockout switch located in the front overhead console prevents opening or actuation of the power sliding door system when activated. In the unlikely event that the power sliding door system develops a fault, the power sliding door can still be operated manually from the interior or exterior door handle similar to a standard manual sliding door.

The PSDM communicates on the Controller Area Network (CAN) data bus circuit. Therefore, the PSDM can generate and store its own Diagnostic Trouble Codes (DTC's). The most reliable, efficient, and accurate means to diagnose the switches, modules, data bus or the electronic controls and communication related to the power sliding door system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

The PSDM is available as a service part and can be serviced separately from the drive assembly should it become damaged or inoperative. Any time a power sliding door component is removed, replaced, door adjustment is performed or diagnostic trouble codes are addressed and erased, a learn cycle must  be performed. The power sliding door learn cycle enables the power sliding door control module to learn or relearn critical information (travel limits, resistance to door travel, door position, etc.) which allows the system to perform properly and safely. To perform a power sliding door learn cycle. Refer to: POWER SLIDING DOOR LEARN CYCLE .
