The power sliding door (PSD) includes several interconnected electronic and mechanical components. Obtain a specific customer concern in order to efficiently diagnose and repair the PSD system. Begin diagnosis with a service writer. Ask the customer for as much detail as possible regarding the conditions under which a failure of the door was noticed. Always include the basic concern, such as "door reverses when closing". The following details might affect the performance of the PSD:
| • | Weather conditions, such as snow or heavy ice |
| • | The van was parked on an incline. |
| • | The van has been parked for a long time, which may cause a weak battery. |
Refer to Power Sliding Door (PSD) Customer Concerns for diagnosis. Verify that all of the mechanical components of the PSD are aligned and operating correctly before you begin diagnosis of the electrical system. The electrical components cannot operate correctly if the mechanical components are not operating correctly.
Generation I and Generation II Power Sliding Doors
There are mechanical differences in the PSD motor clutch assemblies that are installed in the regular wheel base vans and the extended wheel base vans. The Generation I assembly is used in extended wheelbase vans. The Generation II assembly is used in the regular wheel base van. This section includes procedures for servicing both assemblies. Use the correct procedure for the type of van that you are servicing.
