DESCRIPTION
Power Sliding Door is an electro - mechanical system designed to provide power opening and closing of a vehicle's
sliding door through the push of a button of the transmitter key or the main control buttons on the overhead console
or the sub control buttons on the center pillar trim or inside/outside door handle switch.
The power sliding door will reverse direction of travel if resistance to movement is detected while the door is being
closed. If resistance to movement is detected while the power sliding door is being opened, the door will stop moving.
1. DRIVE UNIT
Drive unit (A) consists of a DC motor, optical sensor, clutch, cables and pulleys and wire harness. The clutch and
motor portion of the assembly provides the power and torque required to open or close the sliding door. The clutch
assembly is used to connect or disconnect the motor so that the Sliding Door may be moved manually, if desired.
2.POWER SLIDING DOOR CONTROL MODULE (PSDM)
The PSD System uses a power sliding door control module (microprocessor controller) to operate the drive unit.
Signals are received from the vehicle and used to start or stop power open or close operations. The PSDM cannot
be adjusted or repaired and if found to be faulty, must be replaced.
3.SLIDING DOOR CHIME (C)
When the power sliding door detect the resistance or abnormal operation, the chime will sound.
4.ANTI- PINCH STRIP (D)

TROUBLESHOOTING
Check the following items prior to performing Power Sliding Door System service.
1. Manual movement
Make sure the sliding door moves manually. Place the ON/OFF switch on the overhead console in the OFF
position. Move the door manually and check for proper door fit and latch effort. Check for interference with other
body parts such as latch striker, trim, and weather seals.
2. Battery voltage
Make sure the battery is fully charged. The PSD system is an electronic device and requires a minimum battery
voltage to operate. The PSDM(Power sliding door module) monitors the battery voltage present at the PSDM input
battery input and will not permit operation if the battery voltage is out of range.
3. Fuses
Two fuses protect the battery supply to the PSDM(Power sliding door module), one for Power, and one for logic.
Check that the fuses are intact
4. Repeat Operations
Make sure the customer has not been operating the PSD repeatedly while the vehicle is turned off. The battery will
be discharged and the PSDM(Power sliding door module) will not permit operation.
5. Vehicle on Steep Grade
Make sure the customer has not been operating the PSD system when the vehicle is parked on a steep grade
(greater than 30%). The system will operate but the force of gravity and normal flex of the vehicle body may affect
proper operation.
6. Obstacle Detection
The obstacle detection force is not adjustable. Factors that may affect the force are vehicle grade, battery voltage,
or dirt in sliding door tracks.
7. Outside handle response time
When the vehicle has been parked and OFF, there may be a delay before power operation starts after the outside
handle is pulled. This is normal because the PSDM(Power sliding door module) must wake up and check for proper
conditions before starting a power open operation.
8. The sliding doors are not identical. Open and close times and obstacle detection efforts may vary when comparing
the two doors. This is normal and is caused by vehicle build conditions such as door fit and rolling resistance.
9. Scan tool Diagnostic tool
Connect Scan tool to the K- line and check status of system.
