Kia Sedona (2008 year). Manual - part 471

If the power sliding door is operated while the door is in slightly-opened position (less than 300mm), the 
door is automatically opened fully. If the power sliding door is operated while the door is in slightly-
opened position (more than 300mm), the door is automatically closed completely. 

3. If the door handle is pulled from inside or outside while the door is locked or child safety lock is engaged, 

the power sliding door is not opened.  

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.
