Sliding Door Control Module: Description

Vehicles equipped with a power sliding door utilize a sliding door control module. The sliding door control module is located behind the sliding door trim panel in the center of the door, just above the sliding door motor (Fig 1). This module controls the operation of the door through the Programmable Communication Interface (PCI) J1850 data bus circuit and the Body Control Module. The sliding door control module contains software technology which enables it to detect resistance to door travel and to reverse door travel in order to avoid damage to the door or to avoid possible personal injury if the obstruction is a person. This feature functions in both the opening and closing cycles. If the power sliding door system develops any problems the control module will store and recall Diagnostic Trouble Codes (DTC). The use of a diagnostic scan tool, such as the DRBIII® is required to read and troubleshoot these trouble codes. The sliding door control module can be reflashed if necessary. Refer to the latest Technical Service Bulletin (TSB) Information for any updates.
