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.
