Power Sliding Door System Diagnosis (Part 5 Of 5):

The power opening and closing power sliding door system is a complex system containing many components and modules. In order to obtain conclusive testing, the Programmable Communications Interface (J1850) data bus network and all of the electronic modules that provide inputs to, or receive outputs from the power sliding door system must be checked.

The power sliding door system was designed to be diagnosed with an appropriate diagnostic scan tool, such as the DRB III. The most reliable, efficient, and accurate means to diagnose the power sliding door system requires the use of a DRB III scan tool and the proper Body Diagnostic Procedures manual. The DRB III can be used to observe various switch statuses throughout the power sliding door system to help the technician diagnose a defective switch or component. The DRB III can also be used to actuate various components throughout the power sliding door system to help the technician diagnose a defective component.

Before any testing of the power sliding door system is attempted, the battery should be fully charged, all built-in power sliding door system inhibitors read and understood (Refer to ELECTRICAL/POWER DOORS - OPERATION) and all wire harness and ground connections inspected around the affected areas on the vehicle.

The following are quick reference diagnostic tables to help when diagnosing and testing the power sliding door system.
