(4) When the red light on the universal transmit-

ter begins to flash rapidly (this may take as long as
60 seconds), release both buttons. Your universal
transmitter is now “trained”. To train the other but-
tons, repeat Step 3 and Step 4. Be sure to keep your
hand-held transmitter in case you need to retrain the
universal transmitter.

AMBIENT TEMPERATURE
SENSOR

DESCRIPTION

Ambient air temperature is monitored by the Elec-

tronic Vehicle Information Center (EVIC) through
ambient temperature messages received from the
Powertrain Control Module (PCM) over the Program-
mable Communications Interface (PCI) data bus net-
work. The PCM receives a hard wired input from the
ambient temperature sensor (Fig. 10). The ambient
temperature sensor is a variable resistor mounted to
a bracket that is secured with a screw to the right
side of the headlamp mounting module grille open-
ing, behind the radiator grille and in front of the
engine compartment.

Refer to Powertrain Control Module in Elec-

tronic Control Modules for more information. For
complete circuit diagrams, refer to the appropriate
wiring information. The ambient temperature sensor
cannot be adjusted or repaired and, if faulty or dam-
aged, it must be replaced.

OPERATION

The ambient temperature sensor is a variable

resistor that operates on a five-volt reference signal
sent to it by the Powertrain Control Module (PCM).
The resistance in the sensor changes as temperature
changes, changing the temperature sensor signal cir-
cuit voltage to the PCM. Based upon the resistance
in the sensor, the PCM senses a specific voltage on
the temperature sensor signal circuit, which it is pro-
grammed to correspond to a specific temperature.

The PCM then sends the proper ambient tempera-
ture messages to the EVIC over the PCI data bus.

The thermometer function is supported by the

ambient temperature sensor, a wiring circuit, the
Powertrain Control Module (PCM), the Programma-
ble Communications Interface (PCI) data bus, and a
portion of the Electronic Vehicle Information Center
(EVIC) module. If any portion of the ambient temper-
ature sensor circuit fails, the PCM will self-diagnose
the circuit.

DIAGNOSIS AND TESTING - AMBIENT
TEMPERATURE SENSOR

(1) Turn the ignition switch to the Off position.

Disconnect and isolate the battery negative cable.
Disconnect the ambient temperature sensor wire har-
ness connector.

(2) Measure the resistance of the ambient temper-

ature sensor. At room temperature (approx. 68°F),
the sensor resistance should be between 9-11 Kilo-
hms (9000-11000 ohms). The sensor resistance should
read between these two values. If OK, the sensor is
OK at this time. If not OK, replace the faulty ambi-
ent temperature sensor.

REMOVAL

(1) Open hood, disconnect and isolate the negative

battery cable remote terminal from the remote bat-
tery post (Fig. 11).

(2) Raise and support the vehicle on safety stands.
(3) From behind front bumper fascia, remove the

screw attaching the ambient temperature sensor to
radiator closure panel.

POWER LOCKS

DESCRIPTION

POWER DOOR LOCKS

All doors can be locked or unlocked electrically by

operating the switch on either front door panels.
When the door lock switch is activated the Body Con-
trol Module (BCM) actuates the door lock relay.

All doors can be locked or unlocked mechanically

and independently with their respective locking
knobs. On police vehicles, the rear doors must be
locked or unlocked using the knob located in the
front portion of each rear door panel. These are
accessible only when the front doors are open.

The right and left front door can be locked or

unlocked mechanically from the outside with the key

or all locks can be remotely locked or unlocked with
the Remote Keyless Entry (RKE) transmitter. All
doors can be locked/unlocked from the front doors via
the Central Locking System. The front doors can also
be unlocked by actuation of the inside remote door
handle.

The deck lid can be unlatched by either depressing

the push switch from inside the car, manually by key
from outside or by depressing the remote keyless
entry deck lid release button. This feature is cus-
tomer programmable. The customer has a choice of
immediate release or press and hold release for deck
lid opening. The vehicle is shipped in the press and
hold release mode.

On police vehicles, while the headlamp switch is

either in “approach” or “apprehend” mode, the Panic,
RKE lamp flash for lock and RKE horn chirp will not
operate.

NOTE: The Power Door Lock Motor is not serviced
separately. It is part of the door latch assembly.
Refer to Body, Door - Front, Front Door Latch, or
Body, Door - Rear, Rear Door Latch, Removal and
Installation.

CENTRAL LOCKING

The Central Locking System is part of the Vehicle

Theft Security System (VTSS).

CHILD PROTECTION LOCK

The child protection locks are on the rear doors

only.

DOOR LOCK INHIBIT

The Door Lock Inhibit prevents the vehicle from

being locked with the key in the ignition.

REMOTE KEYLESS ENTRY

The system allows locking and unlocking of vehicle

door(s), deck lid release, and panic by remote control
using a hand held radio frequency transmitter (Fig.
1). The vehicle must be in PARK before the trunk lid
can be unlatched with the transmitter.

The receiver may receive signals from up to four

transmitters. Each transmitter has its own code, and
the code is programmed and stored into receiver
memory. If a transmitter is replaced or additional
transmitters are added, the codes for all units have
to be reprogrammed into the receiver memory. If a
receiver module is replaced, the transmitter codes
must be stored in the new receiver memory.

HORN CHIRP TOGGLE

Once the transmitters have been programmed, the

horn chirp can be enabled/disabled by sending the
horn chirp toggle operation code to the Body Control
Module (BCM). Refer to the Owners Manual for pro-
gramming procedures.

OPERATION

POWER DOOR LOCKS

The Body Control Module (BCM) actuates the

power door lock relays when a door lock switch is
activated. If the door lock switch is pressed for longer
than eight consecutive seconds, the BCM will de-en-
ergize the door lock relay.

The system includes an Automatic Door Locking

feature. The vehicle is shipped with the system
enabled. When the system is disabled the door locks
will work by use of the door lock switches and the
Remote Keyless Entry System only. When the Auto-
matic Door Lock System is enabled the BCM will
automatically lock all the doors when all of the con-
ditions below are met:

• All doors are closed.

• The vehicle speed exceeds 15 ± 1 mph.

• The throttle position sensor tip-in is greater

than 10 ± 2 degrees.

The DRB III

t scan tool is used to enable/disable

the automatic door lock system. Refer to the proper
Body Diagnostic Procedures Manual. They are also
customer programmable. Refer to Owners Manual for
customer programming procedures.

The BCM will automatically re-lock all doors if the

above conditions are met and if any of the doors
become ajar and then closes again.

The power lock motors are also equipped with a

thermal protection system which prevents the motors
from burning out. The motors may chatter if they are
continuously activated.

CENTRAL LOCKING

Using the key, turn the driver’s door cylinder lock

to the lock position, all doors will lock. This feature
operates differently on each door. Turn the key in the
driver’s door to the unlock position once will unlock
the driver’s door only. Turning the key a second time
to the unlock position within five seconds of the first
time will unlock all the doors.

The lock/unlock operation will arm/disarm the

VTSS and will also activate/cancel the illuminated
entry feature.
