One key is used for the ignition, door, and tailgate lock
cylinders. The keys are cut on both edges to make them
reversible.
Key identification is obtained from the five character key
code stamped on the key code tag. From this key code,
the key code cutting combination can be determined from
a code list (available to owners of key cutting equipment
from suppliers).
If key codes are not available from records or tags, the
key code can be obtained from the right hand door lock
cylinder (if lock has not been replaced). Lock cylinders
supplied by the factory as service parts are unmarked.
If the original key is available, the key code cutting
combination can be determined by laying the key on the
diagram shown in the figure.Key Styles

Power Door Lock System
General Description
The circuit consists of the door lock (& power window)
switch, door lock actuator for the front and rear door,
tailgate lock actuator and the door lock key switch.
The front door lock switch±LH is always provided with the
battery voltage.
The key or the inside lock button on both driver's and front
passenger's door can activate the lock mechanism of all
the doors (including the tailgate).
When the driver's door lock switch or the front
passenger's door lock switch is turned on, current flows
for about one second to the door lock actuator of each
door connected in parallel with the front door lock (&
power window) switch±LH to activate the actuator to lock
and unlock the doors.

Anti-Theft System
General Description
The circuit consists of the starter switch, anti±theft &
keyless entry controller, anti±theft horn, front door and
tailgate key switch (detect and tamper) switch, door lock
actuator for each door, engine hood switch, clutch start
switch (M/T), ANTI±THEFT indicator light and mode
switch (A/T).
The system operates as follows: After locking the starter
switch and removing the starter key (this sets the alarm),
if the door is unlocked in any way other than with the
proper key, the headlights will start flashing, the horn
sounds, and the starter circuit is disabled. (However, the
engine hood and all the doors must be locked and closed.)
Once the system has been placed in the warning or alarm
condition, it can be released only when the starter switch
is shifted from ªOFFº to ªACCº by the starter key, or when
the lock of the front door or the tailgate is released (to
activate the detect switch) by the starter key.

SUPPLEMENTAL RESTRAINT SYSTEM9J±5
ªAir Bagº Warning Lamp
Ignition voltage is applied to the ªAIR BAGº warning lamp
when the ignition switch is at the ON or START positions.
The SDM controls the lamp by providing ground with a
lamp driver. The ªAIR BAGº warning lamp is used in the
SRS to do the following:
1. Verify lamp and SDM operation by flashing SEVEN
(7) times when the ignition switch is first turned ªONº.
2. Warn the vehicle driver of SRS electrical system
malfunctions which could potentially affect the
operation of the SRS. These malfunctions could
result in nondeployment in case of a frontal crash or
deployment for conditions less severe than intended.
The ªAIR BAGº warning lamp is the key to driver
notification of SRS malfunctions. For proper lamp
operation, refer to the ªSRS Diagnostic System Checkº in
this section.
060R200035
SRS Coil Assembly
The SRS coil assembly consists of two current carrying
coils. This is attached to the steering column and allow
rotation of the steering wheel while maintaining
continuous contact of the driver deployment loop to the
driver air bag assembly.
There is a shorting clip on the yellow 2±pin connector near
the base of steering column which connects the SRS coil
to the SRS wiring harness.
The shorting clip shorts to the SRS coil and driver air bag
assembly when the yellow 2±pin connector is
disconnected. The circuit to the driver air bag assembly is
shorted in this way to help prevent unwanted deployment
of the air bag when servicing the steering column or other
SRS components.
825RS071
Air Bag Assemblies
The air bag assembly consist of an inflatable air bag
assembly and an inflator (a canister of gas±generating
material and an initiating device). When the vehicle is in a
frontal crash of sufficient force.
The SDM causes current flow through the deployment
loops. Current passing through the inflator ignites the
material in the air bag assembly. The gas produced from
this reaction rapidly inflates the air bag assembly.
There is a shorting clip on the driver air bag assembly
connector which connects the SRS coil assembly. The
shorting clip shorts across the driver air bag assembly
circuits when driver air bag assembly connector is
disconnected.
The circuit to the driver air bag assembly is shorted in this
way to help prevent unwanted deployment of the air bag
when servicing the driver air bag assembly, the steering
column or other SRS components.
827RX001

SUPPLEMENTAL RESTRAINT SYSTEM 9J±6
There is a shorting clip on the passenger air bag
assembly connector which connects to the SRS harness.
The shorting clip shorts across the passenger air bag
assembly circuit when the passenger air bag assembly
connector is disconnected. The circuit to the passenger
air bag assembly is shorted in this way to help prevent
unwanted deployment of the air bag when servicing the
passenger air bag assembly, the instrument panel or
other SRS components.

Definition
Air Bag
An inflatable cloth cushion designed to deploy in certain
frontal crashes. It supplements the protection offered by
the seat belts by distributing the impact load more evenly
over the vehicle occupant's head and torso.
Asynchronous
Performed in a nonperiodic fashion, (i. e., no defined time
or interval).
(B+)
Battery voltage, (B+) The voltage available at the battery
at the time of the indicated measurement. With the key
ªONº and the engine not running, the system voltage will
likely be between 12 and 12.5 volts. At idle the voltage
may be 14 to 16 volts. The voltage could be as low as 10
volts during engine cranking.
Bulb Check
The SDM will cause the ªAIR BAGº warning lamp to flash
seven times and then go ªOFFº whenever the ignition
switch transitions to the ON position from any other
ignition switch position and no malfunctions are detected.
ªCONTINUOUS MONITORINGº
Tests performed by the SDM on the SRS every 100
milliseconds while ªIgnition 1º voltage is in the normal
operating voltage range at the SDM.
Data Link Connector (DLC)
Formerly ªDLCº a connector which allows communication
with an external computer, such as a scan tool.
Datum Line
A base line parallel to the plane of the underbody or frame
from which all vertical measurements originate.
