PEDAL - ADJUSTABLE
DESCRIPTION
The Adjustable Pedals System (APS) is designed to
enable the fore and aft repositioning of the brake and
accelerator pedals. This results in improved ergonom-
ics in relation to the steering wheel for taller and
shorter drivers. Being able to adjust the pedal posi-
tions also allows the driver to set steering wheel tilt
and seat position to the most comfortable position.
The effort required for pedal application will not
change regardless of pedal position.
The adjustable pedal system allows the pedals to
adjust up to 3 inches (75 mm) at a rate of approxi-
mately 0.4 in./sec. (9 mm/sec.). An adjustment switch
is located on the left side of the steering column
lower shroud.
If the vehicle is equipped with Remote Keyless
Entry (RKE), an optional memory feature is avail-
able.
The serviceable components of the APS are:
²Adjustable pedal assembly (includes motor,
cables, pedals, gear box, sensor and module)
²Adjustable pedal module (Refer to 8 - ELECTRI-
CAL/ELECTRONIC CONTROL MODULES/
ADJUSTABLE PEDAL MODULE)
²Adjustable pedal switch
²Pedal position sensor
OPERATION
Change of pedal position is accomplished by means
of a motor driven screw. Operating the adjustable
pedal switch activates the pedal drive motor. The
pedal drive motor turns a screw that changes the
position of the accelerator pedal. The motor also
drives a cable connected to a gear box that changes
the brake pedal position the same distance as the
accelerator pedal. The pedals can be moved rearward
(closer to the driver) or forward (away from driver).
Each pedal is moved on its activating lever to a posi-
tion where the driver feels most comfortable. The
position and operation of the activating levers are not
changed.
Pedal adjustment is inhibited when the vehicle is
in reverse or when cruise control is engaged. The
Electronic Vehicle Information Center (EVIC) will
display a message when the Adjustable Pedal Module
(APM) is disabled. i.e.:9Adjustable Pedal Disabled -
Cruise Control Engaged9or9Adjustable Pedal Dis-
abled - Vehicle in Reverse9.
Foot pressure or debris can stall pedal adjustment.

BODY CONTROL MODULE
DESCRIPTION
The Body Control Module (BCM) is located in the
passenger compartment, attached to the bulkhead
underneath the left side of the instrument panel.
The BCM utilizes integrated circuitry and informa-
tion carried on the Programmable Communications
Interface (PCI) data bus network along with many
hard wired inputs to monitor many sensor and
switch inputs throughout the vehicle. In response to
those inputs, the internal circuitry and programming
of the BCM allow it to control and integrate many
electronic functions and features of the vehicle
through both hard wired outputs and the transmis-
sion of electronic message outputs to other electronic
modules in the vehicle over the PCI data bus.

MEMORY SEAT/MIRROR
MODULE
DESCRIPTION
Vehicles equipped with the memory seat/mirror
option, utilize a memory module located under the
drivers front seat. This module is basically wired in-
line between the power seat switch and the power
seat track/adjuster motors, or in-line between the
power mirror switch and the power side view mir-
ror(s) motor(s). The MSMM contains a central pro-
cessing unit that communicates with other modules
on the Programmable Communications Interface
(PCI) data bus network.
The Memory Seat/Mirror Module (MSMM) receives
hard wired inputs from the driver power seat switch
and the potentiometers on each of the driver side
power seat track motors, or from the power mirror
switch and the potentiometers on the side view mir-
ror. The MSMM receives messages over the PCI data
bus from the Body Control Module (BCM) (memory
switch status), the Powertrain Control Module (PCM)
(vehicle speed status). The MSMM will prevent the
seat memory recall function from being initiated if
the driver side seat belt is buckled, if the transmis-
sion gear selector lever is not in the Park or Neutral
positions, or if the vehicle is moving.
For diagnosis of the MSMM or the PCI data bus, a
DRB IIItscan tool and the proper Diagnostic Proce-
dures manual are recommended. The MSMM cannot
be repaired and, if faulty or damaged, it must be
replaced. Refer toMemory Systemin the Power
Seat or Power Mirror section of this manual for more
information on the memory system option.
OPERATION
When memory system operation is requested
(depressing of the memory switch), a resistor multi-
plexed signal is sent from the memory switch to the
body control module (BCM). The body control module
will then send the appropriate signals out to the
memory/mirror seat module, the memory/mirror seat
module then applies the voltage supply to the power
seat track or side-view mirror if the proper require-
ments are met. The vehicle speed must equal zero
and the transmission must be in park or neutral in
order for the memory system to function.
DIAGNOSIS AND TESTING - MEMORY
SEAT/MIRROR MODULE
Visually inspect the related wiring harness connec-
tors. Look for broken, bent, pushed out, or corroded
terminals. If any of the above conditions are present,
repair as necessary. If not, use a DRB IIItscan tool
and the proper Diagnostic Procedures Manual to testthe memory/mirror seat module. For complete circuit
diagrams, refer toWiring Diagrams.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the driver side front bucket seat
retaining nuts from under the vehicle (Refer to 23 -
BODY/SEATS/SEAT - REMOVAL).
(3) Lift the drivers seat up and out of the mount-
ing holes in the floor pan and lay the seat rearward
to access the module located under the seat. It is not
necessary to disconnect the seat electrical, just use
care not to damage the wiring by over-extending.
(4) Disconnect the memory/mirror seat module
electrical connectors. Depress the retaining tab and
pull straight apart.
(5) Remove the module retaining bolts and remove
the module from the bracket.

SLIDING DOOR CONTROL
MODULE
DESCRIPTION
Vehicles equipped with a power sliding door utilize
a sliding door control module. The sliding door con-
trol module is located behind the sliding door trim
panel in the center of the door, just above the sliding
door motor (Fig. 20). This module controls the opera-
tion of the door through the Programmable Commu-
nication 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 DRB IIItis
required to read and troubleshoot these trouble
codes. The sliding door control module can be

DOOR CYLINDER LOCK
SWITCH
DESCRIPTION
The Door Cylinder Lock Switch is used to:
²Unlock/Lock all the doors via the Central Lock-
ing feature.
²Arm/Disarm the Vehicle Theft Security System.
²Trigger the Illuminated Entry feature.
The door cylinder lock switch is mounted to the
rear of the driver and passenger door lock cylinders.
When installed on the rear of the cylinder, there is a
tab on the lock cylinder that aligns with the switch
to prevent it from turning. An anti-rotating device.
The door cylinder lock switch is a one time use
switch. Once it is removed from the rear of the door
lock cylinder, it may not be reinstalled and a new
switch must be used.
OPERATION
When the Door Cylinder Lock Switch is turned
either way using the door key cylinder, the BCM
reads a direct message signal from the switch, via
the Programmable Communication Interface (PCI)
bus.
If turning the key cylinder once, toward the front
of the vehicle (for either driver or passenger doors),
this will:
(1) Mechanically unlock the door lock.
(2) Disarm the Vehicle Theft Security System (if
equipped).
(3) Turn on the Illuminated Entry (if equipped) for
approximately 30 seconds.
If the key cylinder is turned to the unlock position
(toward the front of vehicle) twice within two sec-
onds, all the doors and liftgate will unlock (if
equipped with the central locking feature).
To lock the vehicle using the door cylinder lock
switch, turn the key cylinder toward the rear of the
vehicle (either passenger or driver doors) once. This
will lock the door that you are using the key on. If
equipped with the central locking feature, this will
lock all the other doors and liftgate. Furthermore,
this will arm the vehicle theft security system and
turn off the illuminated entry.
DIAGNOSIS AND TESTING - DOOR CYLINDER
