SLIDING DOOR CONTROL
MODULE
DESCRIPTION
Vehicles equipped with a power sliding door system
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. 15). This module controls the opera-
tion of the door through the Programmable Commu-
nication Interface (PCI) data bus circuit and the
Body Control Module (BCM). 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 DRB IIItis
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.The power door control module is a replaceable
component and cannot be repaired, if found to be
faulty it must be replaced.
OPERATION
The power sliding door control module serves as
the main computer for the power sliding door system.
All power door functions are processed through the
power sliding door control module and/or the vehicles
Body Control Module (BCM). At the start of a power
open command, a signal is sent to the BCM and then
to the power sliding door control module via the Pro-
grammable Communication Interface (PCI) data bus
circuit. This signal, generated by any of the power
door command switches, tells the power sliding door
control module to activate a power latch release,
engage the clutch assembly and drive the door into
the full open position. If an obstacle is felt during
this power open cycle, the module will reverse direc-
tion and close the door. This process is also enabled
during a power close cycle. This process will repeat
three times, and if a fourth obstacle is detected, the
door will go into full manual mode. Once the full
open position is obtained, a hold open latch assembly
mounted full open switch tells the power sliding door
control module that the door has reached the full
open position. If the power sliding door system devel-
ops any problems the power sliding door control mod-
ule will store and recall Diagnostic Trouble Codes
(DTC). The use of a diagnostic scan tool, such as the
DRB IIItis required to read and troubleshoot these
trouble codes.
DIAGNOSIS AND TESTING
SLIDING DOOR CONTROL MODULE
Any diagnosis of the power sliding door sys-
tem should begin with the use of the DRB IIIt
diagnostic tool. For information on the use of
the DRB IIIt, refer to the appropriate Diagnos-
tic Procedures information.
Inspect the related wiring harness connectors for
broken, bent, pushed out, or corroded terminals.
Refer to the appropriate wiring information.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the appropriate door trim panel from
the vehicle. (Refer to 23 - BODY/DOORS - SLIDING/
TRIM PANEL - REMOVAL)
(3) Remove the weather shield.
