CLEANING AND INSPECTION
HEADLAMP CLEANING
This vehicle is equipped with plastic headlights
that are lighter and less susceptible to stone break-
age than glass headlights.
This plastic is not as scratch resistant as glass and
therefore a different lens cleaning procedures must
be followed.
To minimize the possibility of scratching the lenses
and reducing light output, avoid wiping with a dry
cloth. To remove road dirt, wash with a mild soap
solution followed by rinsing with water.
Do not use abrasive cleaning components, solvents,
steel wool or other aggressive material to clean the
lenses.

INTRODUCTION
The key fob transmitter has three buttons to actu-
ate and program the Remote Keyless Entry (RKE)
system (Fig. 1).
²UNLOCK: Pressing the UNLOCK button once
will unlock the driver door and activate the illumi-
nated entry system and disarm Vehicle Theft Secu-
rity System, if equipped. Pressing the UNLOCK
button twice within five seconds will unlock all doors
and activate the illuminated entry system.
²LOCK: Pressing the LOCK button locks all
doors and sounds horn (chirp) and arm the Vehicle
Theft Security System. The chirp verifies the door
lock operation.
²PANIC: Pressing the PANIC button sounds the
horns at half second intervals, flashes the exterior
lamps, and turns ON the interior lamps. The panic
alarm will remain on for three minutes, or until the
PANIC button is actuated again or the ignition
switch is turned to the RUN position.
²The Remote Keyless Entry Module is capable of
retaining the transmitter Vehicle Access Code(s)
(VAC) in its memory even after vehicle power has
been interrupted.
²The RKE system activates the optional memory
seat and mirror system, if equipped. Two primary
key fob transmitters can be programmed to actuate
memory seat and mirror setting 1 or 2. Two addi-
tional key fob transmitters can be added, but they
will not be able to operate the memory seat and mir-
ror system. Refer to Group 8R, Power Seats and
Group 8T, Power Mirrors for memory system infor-
mation.
VEHICLE ACCESS CODE (VAC) PROGRAMMING
The RKE module is capable of retaining up to four
different Vehicle Access Codes. Whenever the vehicle
battery power is interrupted the RKE Module willretain all vehicle access codes in its memory. When
replacing or adding a key fob transmitter (maximum
4) a functional key fob transmitter is required to pro-
gram the RKE Module to accept the new Vehicle
Access Code. If a functional key fob transmitter is
not available, a scan tool (DRB) can be used to pro-
gram the RKE Module. Refer to the proper Body
Diagnostic Procedures manual for Vehicle Access
Code programming procedures using a scan tool.

GENERAL INFORMATION
INTRODUCTION
Vehicles equipped with the Vehicle Theft Security
System (VTSS) system, the doors, liftgate, hood and
ignition circuit are monitored by the Body Control
Module (BCM) when the system is armed. The VTSS
will prevent the engine from starting until the BCM
receives a disarm signal. If the VTSS is triggered,
the horn will pulse, headlamps/marker lamps will
flash, and the VTSS warning lamp will flash. If BCM
determines the threat to be false and the VTSS is not
triggered again, the system will shut down and
rearm itself after three minutes. The VTSS monitor-
ing portion of the system is split into two sections.
The engine compartment section and the passenger
compartment section. If a malfunction occurs in the
engine compartment section, the passenger compart-
ment section would still arm and function normally.
If an electrical malfunction occurs in either section of
the system a Diagnostic Trouble Code (DTC) would
be stored the BCM memory to aid system repair.
DTCs can be retrieved using scan tool (DRB)
attached to the diagnostic connector above the accel-
erator pedal.
ENABLING
To initialize the VTSS feature the operator must,
with the engine compartment hood open, cycle the
key in the liftgate key cylinder to the unlock position
giving the BCM a disarm signal. At this time the
visual alarm outputs the headlamps and marker
lamps will function. However the audio alarm output
the horn and engine disable portion of the VTSS will
not function until there has been twenty consecutiveengine run cycles. When this has occurred the total
VTSS will function.
If during alarm being set the BCM receives a
request from the RKE module to enter PANIC mode
the BCM will cancel the alarm, return VTSS armed
state and then perform the RKE PANIC feature.
DESCRIPTION AND OPERATION
ARMING PROCEDURE
METHOD-A
(1) With the key removed from the ignition lock
and any door open, actuate one of the following:
²Power door lock button to LOCK,
²Key fob LOCK button
²Door lock key cylinder to locked position.
(2) Close all opened doors.
(3) After the last door is closed, an arming time-
out period of sixteen seconds will start, then the
VTSS will become armed.
METHOD-B
Actuating the key fob transmitter LOCK button,
key locking the front doors or liftgate with the doors
closed and the ignition locked will begin the arming
time-out period. If method-A, 16 second time-out
sequence was in process when method-B was actu-
ated, the 16 second time-out will restart from the
time of the second actuation.
If the security lamp does not illuminate at all upon
final door closure, it indicates that the system is not
arming.
The current VTSS status armed or disarmed shall
be maintained in memory to prevent battery discon-
nects from disarming the system.
NSVEHICLE THEFT SECURITY SYSTEM 8Q - 1

TIME-OUT PERIOD
The VTSS requires 16 consecutive seconds to time-
out and arm the alarm. If a door is key unlocked, key
fob unlocked. or the ignition is switched ON, the
VTSS will cancel out. To reset the VTSS, perform
methods A or B.
TRIGGERING THE VTSS
After the VTSS is armed, following actions will
trigger the alarm:
²Opening any door.
²Opening the hood
²Turning the ignition to the ON or unlock posi-
tion.
²The ignition switch can be turned to the acces-
sory position without triggering alarm system.

GENERAL INFORMATION
INTRODUCTION
This section will cover components either regulated
or controlled by the Powertrain Control Module
(PCM). The fuel heater relay, fuel heater and fuel
gauge are not operated by the PCM. These compo-
nents are controlled by the ignition (key) switch. All
other fuel system electrical components necessary to
operate the engine are controlled or regulated by the
PCM. Refer to the following PCM description for
more information.
Certain fuel system component failures may cause
a no start, or prevent the engine from running. It is
important to know that the PCM has a featurewhere, if possible, it will ignore the failed sensor, set
a code related to the sensor, and operate the engine
in a ªLimp Homeº mode. When the PCM is operating
in a ªLimp Homeº mode, the Diesel Glow Plug lamp
on the instrument panel will be constantly illumi-
nated, and the engine will most likely have a notice-
able loss of performance. An example of this would be
an Accelerator Pedal Position Sensor failure, and in
that situation, the engine would run at a constant
1100 RPM, regardless of the actual position of the
pedal. This is the most extreme of the three ªLimp
Homeº modes.
In addition to indicating that the glow plugs are
hot enough to start combustion, the Glow Plug Lamp
is also used in the diagnosis of the PCM, and when
NS/GSFUEL SYSTEMÐ2.5L DIESEL ENGINE/2.0L GAS ENGINE 14 - 43

illuminated constantly, it usually indicates a problem
has been detected somewhere within the fuel system.
The DRBIII scan tool is the best method for commu-
nicating with the PCM to diagnose faults within the
system.
DESCRIPTION AND OPERATION
POWERTRAIN CONTROL MODULE (PCM)
The Powertrain Control Module (PCM) is mounted
in the center consule to a bracket located in front of
the Air Bag Module (Fig. 1).
The PCM is a pre±programmed, dual micro±proces-
sor digital computer. It will either directly operate or
partially regulate the:
²Speed Control
²Speed Control LED lamp
²Fuel Timing Solenoid
²Glow Plug Relay
²Glow Plugs
²EGR Solenoid
²Glow Plug Lamp
²Diesel PCM Relay
²Air Conditioning Operation
²Tachometer
²Exhaust Gas Recirculation (EGR) Solenoid
The PCM can adapt its programming to meet
changing operating conditions.
The PCM receives input signals from various
switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operationsthrough different system components. These compo-
nents are referred to asPCM Outputs.The sensors
and switches that provide inputs to the PCM are con-
sideredPCM Inputs.
PCM Inputs are:
²Air Conditioning Selection
