travel. This allows the power sliding door to stop and
reverse direction any time an obstruction is felt or
any of the command switches are operated (while
closing only). Battery voltage is supplied to the power
sliding door system through a 40 amp fuse, located in
the Integrated Power Module (IPM) assembly. The
child lockout switch prevents children from opening
or actuating the power sliding door system when
desired. In the unlikely event that the power sliding
door system develops a fault, the power sliding door
can still be operated manually from the interior or
exterior door handle, just like a standard manual
sliding door.
The power sliding door control module communi-
cates on the Programmable Communication Interface
(PCI) Data Bus Circuit. Therefore, the power sliding
door control module can generate and store its own
Diagnostic Trouble Codes (DTC). A diagnostic scan
tool, such as the DRB III
t is used to read and diag-
nose these trouble codes.
NOTE: It may be possible to generate Sliding Door
Diagnostic Trouble Codes during normal power
sliding door operation. Refer to the Body Diagnos-
tic Manual for a complete list of diagnostic routines.
For additional information, (Refer to 8 - ELECTRI-
CAL/POWER DOORS - OPERATION). Refer to the
appropriate wiring information for complete circuit
schematic or connector pin-out information.
WARNING: BE CERTAIN TO READ ALL WARNINGS
AND CAUTIONS IN POWER SLIDING DOOR OPER-
ATION BEFORE ATTEMPTING ANY SERVICE OF
THE POWER SLIDING DOOR SYSTEM OR COMPO-
NENTS.
OPERATION
With the push of a power sliding door open/close
command switch (key fob, overhead console or B-pil-
lar mounted) a signal is sent out to the Body Control
Module (BCM). The BCM then sends a signal out on
the Programmable Communication Interface (PCI)
Data Bus circuit to the power sliding door module.
The power sliding door module then signals the
power sliding door latch to release the door to the
unlatched and movable position. The motor then
starts an open cycle.
During the door cycle, if the power sliding door
module detects sufficient resistance to door travel,
such as an obstruction in the door’s path, the power
sliding door module will immediately stop door move-
ment and reverse door travel to the full open or
closed position. The ability for the power sliding door
module to detect resistance to door travel is accom-
plished by hall effect sensors detecting the door
motor speed.
The power sliding door control module has the abil-
ity to learn. Anytime a door is opened or closed using
the power sliding door system the module learns
from its cycle. If a replacement power sliding door
component is installed or a door adjustment is made,
the module must re-learn the effort required to open
or close the door. A learn cycle can be performed with
a complete cycle of the door, using any one of the
command switches or with the DRB III
t, or equiva-
lent scan tool. (Refer to 8 - ELECTRICAL/POWER
DOORS

The power sliding door system is designed with a
number of system inhibitors. These inhibitors are
necessary for safety and/or feasibility of the power
sliding door system. The power sliding door system
inhibitors are:
• The power sliding door must be in the full open
or closed position in order for the power sliding door
system to start a cycle. If the door is not in this posi-
tion (based on the input from the full open, pawl or
ratchet switches) the door control module will not
respond to command switch inputs.
• The transmission must be in park or neutral
in order for the power sliding door system to start a
cycle.
• The child lockout switch must be in the
“UNLOCKED” position in order for the power sliding
door systems B-pillar switches to function.

• If multiple obstacles are detected during the
same power open or close cycle the power sliding
door may go into full manual mode.
• If severe Diagnostic Trouble Codes (DTC) are
stored in the power sliding door control module the
power sliding door may go into full manual mode.
• Due to the high pressure created in the passen-
ger compartment with the blower motor on high, the
power sliding door may not complete a power close
cycle unless a window is cracked, allowing the pres-
sure to escape. This situation will only be experi-
enced on some vehicles, or vehicles with brand new
side door weather seals installed.
• The fuel tank filler door must be in the closed
position. Due to the sliding door interference with
the open fuel tank filler door, a mechanical linkage
prevents the side door from opening and striking the
fuel door. Refer to the Body section of this manual for
detailed information on the fuel door lockout feature.

DIAGNOSIS AND TESTING
POWER SLIDING DOOR SYSTEM
The power sliding door system contains many com-
ponents and modules. In order to obtain conclusive
testing, the Programmable Communications Interface
(PCI) data bus network and all of the electronic mod-
ules 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
t. The most reliable, efficient,
and accurate means to diagnose the power sliding
door system requires the use of a DRB III
t scan tool
and the proper Body Diagnostic Procedures manual.
The DRB III
t 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
t can also be used to actuate
various components throughout the power sliding
door system to help the technician diagnose a defec-
tive 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 8 - 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 slid-
ing door system.
