Some vehicles are equipped with a power sliding door system. The components of the power sliding door system are:

• Power sliding door drive assembly (3)
• Power Sliding Door Control Module (PSDM) (4)
• Hands Free Power sliding Door Control Module (HFEPSD)
• Power Distribution Center (PDC)
• Instrument Cluster (IC)
• Read Door Control Modules (RDCM)
• Radio Frequency Hub (RFHM)
• Body Control Module (BCM)
• Sliding door wire harness and chain link track (Contains the wiring harness that connects the door electrical to the body electrical) (2)
• Controller Area Network (CAN) data bus
• B-pillar switches (1)
• Overhead console switches
• Key fob switches
• Outside handle with button (non-passive) - There is also an external button on outside handle that can be used to power open and close the door. Multiple presses will change the doors direction under power operation
• Power sliding door cinching latches (includes the latch ratchet primary (ajar) switch, sector gear switch, pawl switch, handle switch and cinch/release motor)

Each power sliding door is equipped with a power sliding door drive assembly with PSDM. The drive assembly is mounted to the body in the lower sliding door sill area with the use of five retaining nuts. The PSDM is mounted directly to the inboard side of the drive assembly with two retaining screws. The power sliding door motor is also located on the inboard side of the drive assembly. Unlike the PSDM which can be serviced separately, the motor is not available as a service item and must be replaced with the drive assembly should it become damaged or inoperative. 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.

The cinching latch assembly is located in the rear of the power sliding door, near the body line. The latch has integral components (latch ratchet primary (ajar) switch, sector gear switch pawl switch, handle switch and cinch/release motor) that are responsible for the cinching and latching of the sliding door to the body striker. In addition the latch components also send status messages back to the PSDM via the RDCM and CAN data bus circuit.

One quick pull on the handle will cause the door to begin a power cycle. The handle switch located on the cinch latch is used as an additional input to initiate door operation. Pressing the overhead console switch while the door is moving in mid-travel will terminate the power cycle to put the door in manual mode, and there will be no handle activation allowed until the door is back in full open or closed position.

Power close (only) in gear feature. The door can be power closed when the vehicle is out of Park or Neutral.

The B-pillar switch is located on the lower B-pillar trim panel and allows the rear occupants to power open or close the sliding doors.

The overhead power sliding door switches, including lock out switch, are mounted in the front overhead console of the vehicle. The switches are not serviced individually, they are part of a switch pod integral to the overhead console.

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 Body Control Module (BCM). 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.
