GENERAL INFORMATION
JUMP-STARTING, VEHICLE EQUIPPED
WITH THEFT SECURITY SYSTEM . After the
booster battery has been connected, the Theft System
must be turned OFF. Using the key, lock then un-
lock either front door. This turns the Theft System
OFF and the remainder of the Jump-Starting proce-
dure can be followed. If this procedure is not followed, the Theft System
electronics will prevent the engine from starting. If a new Powertrain Control Module is installed,
the engine has to be cranked 20 times before the
alarm system activated. This passive system is designed to protect against
whole vehicle theft. The system monitors vehicle
doors, hood, trunk key cylinder, and ignition action
for unauthorized operation. The alarm activates by
sounding the horn, flashing the park and tail lamps,
and providing an engine kill feature (Fig. 1). Passive arming occurs upon normal vehicle exit,
open door, lock with power locks, close door. The SET
lamp in the panel will flash for 15 seconds, indicat-
ing that arming is in progress. If no monitored sys-
tems are activated during this period, the system
will arm. If the hood or trunk key cylinder switches
are not sensed by the system. The SET lamp will re-
main lit during the arming process, although the sys-
tem will still arm. The system is to be considered as
an active armed system when using the Remote Key-
less Entry. If the SET lamp does not illuminate at all
upon door closing it indicates that the system is not
arming. Passive disarming occurs upon normal vehicle en-
try unlocking either door with the key, or unlocking
using the Remote Keyless transmitter. This disarm-
ing will also halt the alarm once it has been acti-
vated. Whenever the battery is disconnected and recon-
nected, the Vehicle Theft Security System enters
power up alarm mode which flashes the park and tail
lamps and prevents the engine from running. To exit
this mode, the system must be disarmed as men-
tioned above. A tamper alert exists to notify the driver that the
alarm had been activated, and the alarm has since
timed-out for more than 18 minutes. This alert con-
sists of 3 horn pulses when the vehicle is disarmed. The alarm system will not arm if the doors are
manually locked, providing a manual override of the
alarm.
WHAT WILL TRIGGER THE SYSTEM
One of the following actions will trigger the system
while it is armed. Without properly disarming sys-
tem, by using the key or the remote transmitter. (1) Opening the HOOD.
(2) Opening any DOOR.
(3) Removing the TRUNK KEY CYLINDER.
(4) Turning the IGNITION ON.
(5) The ignition switch can be turned to the acces-
sory position without triggering alarm system.
SYSTEM SELF-TESTS
A diagnostics mode is available in the system to
verify operation of all monitored switches or circuits.
To enter diagnostics, cycle the ignition key to the ac-
cessory position 3 times, leaving the key in this po-
sition. Upon entering diagnostics, the park and tail lamps
will begin flashing to verify their operation. In addi-
tion, the horn will sound twice to indicate that the
trunk key cylinder is in its proper position. Return-
ing the ignition to the OFF position will stop the
lamps from flashing while keeping the system in di-
agnostics. While in diagnostics mode, a horn pulse should oc-
cur at each of the following events indicating proper
operation: (1) Beginning with all doors closed, open then close
each door. The horn will sound when the door ajar
switch closes, and then again when the switch opens.
There must b e a 1 second delay between closing and
opening the switch. (2) Open, then close the hood. The horn will sound
when the hood is opened, and again when it is closed.
Ä VEHICLE THEFT SECURITY SYSTEM 8Q - 1

(3) Activate the power door locks in both the
LOCK and UNLOCK directions. The horn will sound
after each activation. (4) Rotate the key in each of the door lock cylin-
ders to the unlock position. The horn will sound as
the switch closes, and again when it opens. There
must b e a 1 second delay between changing switch
states, or the horn will not sound.
² Press the LOCK button,horn will sound.
² Press the UNLOCK button, horn will sound.
(5) Cycle the key to the ignition RUN position. A
single horn pulse will indicate proper operation of
the ignition input. This will also take the module out
of the diagnostics mode. For any of these tests, if the
switch does not remain open or closed for at least 1
second, the horn will only sound once. The lack of a horn pulse, during any operation, in-
dicates a switch failure. Check for continuity at the
switch, if this is good, check for an open or shorted
wire between the switch and alarm module. Also,
check if a new powertrain control module has been
installed recently. Vehicle Theft Security System will
not function until 20 engine cranks. Whenever a Vehicle Theft Security System mal-
function occurs, first verify that the wire harness is
properly connected to all connectors before starting
normal diagnosis and repair procedures. Refer to Ve-
hicle Theft Security System Diagnosis Chart (Fig. 3).VEHICLE THEFT SECURITY SYSTEM MODULE
REPLACEMENT
If the Vehicle Theft Security System module is be-
ing removed and no replacement module is being in-
stalled, the module wiring must be disconnected

ity 9 and pin 7 of the control module 25-way connec-
tor. The vehicle speed sensor signal can be tested
with a volt/ohmmeter at pin 7 of the control module
25-way connector. Turn on the vehicle ignition and
check fo r a 5 volt signal as the vehicle is moved
about 3 to 5 feet. If not repair open wiring, terminal
push out, bad crimp, drive in vehicle speed sensor,
etc., as necessary to correct condition. Ensure that
the 25-way connector is plugged into the control
module securely. Road test vehicle after repairs have
been made to ensure that no recalls can occur while
moving.
CONDITION: INSTRUMENT CLUSTER SPEEDOMETER STAYS AT 0 MPH/ (0 KM/H)WHILE VEHICLE IS MOVING, BODYCOMPUTER DOES NOT LOCK DOORS AT 15MPH (24 KM/H), AND THE SPEED CONTROLWILL NOT ACCEPT A SPEED SET.
PROCEDURE
(1) Remove driver's seat anchor bolts and nuts. Ad-
just the driver's seat to a safe driving position. Dis-
connect the 25-way connector from the memory seat
control module. Replace the driver's seat anchor bolts
and nuts. Road test the vehicle to complete this diag-
nosis. If the doors lock, the cruise control accepts a
set, and the speedometer now works, replace the
Memory Seat control module. (2) After replacing the Memory Seat control mod-
ule, perform the memory seat diagnostic self tests.
This teaches the new module it's soft limits and now
re-road test the vehicle before returning it to the cus-
tomer.
CONDITION: NO SEAT MOVEMENT IN THE RECALL MODE, SEAT WILL MOVE BYMANUAL SWITCH ACTUATION IN ALLDIRECTIONS WITHOUT STALL DETECTION.
PROCEDURE
(1) Check for 5 volts at pin 10 of the control mod-
ule 25-way connector. This is the 5 volt feed from the
control module to the seat track position sensing po-
tentiometer. (2) Check for ground at pin 8 of the control module
25-way connector. To test for ground, one lead of the
voltmeter must be connected to either the 5 volt sup-
ply for the control module or the battery positive. If
the sense voltage and ground are NOT present at the
above pins of the 21-way control module connector.
When the seat switch is pressed, replace the control
module. An inadvertent application of battery volt-
age to the circuit could damaged the control module.
If the voltage and ground circuits are present then
continue this procedure. (3) Check for 5 volts at pin 5 of the natural 5-way
connector plugged into the power seat adjuster mo-
tors end-bell. (4) Check for ground at pin 4 of the natural 5-way
connector plugged into the power seat adjuster mo-
tors end-bell. If the power seat adjuster still has no
movement in the recall mode, then continue this pro-
cedure. (5) Disconnect the natural 5-way connector from
the power seat adjuster motors end-bell. (6) Check with an ohmmeter for a resistance read-
ing that may be from 2600 to 4000 ohms between
pins 4 and 5 of the motors end-bell connector. If
there is an open circuit reading or the reading ob-
tained falls outside this range, then replace the seat
motor package assembly. After replacement of the
seat motor package, reconnect all wiring connectors
and reinstall seat assembly in vehicle. Operate the
switches manually to cause maximum seat move-
ment in all directions. Perform the memory seat di-
agnostic self check so the control module will learn
the new soft limits of the assembly.
CONDITION: NO SEAT TRACK FORWARD OR REARWARD MOVEMENT IN THE RECALLMODE, SEAT TRACK WILL MOVE FORWARDOR REARWARD BY MANUAL SWITCHACTUATION WITHOUT STALL DETECTION.
PROCEDURE
(1) Check for a voltage at pin 12 of the control
module 21-way connector. Less than 5 volts for the
seat track fully forward and more than 0 volts when
fully rearward. This voltage should vary correspond-
ing to the position. (2) Check for a voltage at pin 1 of the natural
5-way connector, Same as in step (1) above. The
ground lead connected to pin 4 of the 5-way connec-
tor. If the voltage reading is at 0 volts, disconnect
the 5-way natural connector and check for a short to
ground in the harness. If no short is found, reconnect
the connector and continue the procedure. (3) Check for the voltage to vary as noted above, if
it does not vary as the seat track is moved forward
and rearward, the sensing potentiometer is defective.
Replace the seat motor package assembly. After re-
placement of the seat motor package, reconnect all
wiring connectors and reinstall seat assembly in ve-
hicle. Operate the switches manually to cause maxi-
mum seat movement in all directions. Perform the
memory seat diagnostic self check so the control
module will learn the new soft limits of the assem-
bly.

GENERAL INFORMATION
Front and rear door window lift motors are of the
permanent magnet type. A positive and negative bat-
tery connection to either of the two motor terminals
will cause the motor to rotate in one direction. Re-
versing current through these same two connections
will cause the motor to rotate in the opposite direc-
tion. Each individual motor is grounded through the
master switch by a black wire attached to the left
cowl panel. It is necessary that the window be free to slide up
and down in the glass channels or tubes and tracks.
If the window is not free to move up and down, the
window lift motor will not be able to move the glass. To determine if the glass is free is to disconnect the
regulator from the glass lift plate, and slide the win-
dow up and down by hand. For conventional arm-sec-
tor regulators, after the lift plate is detached from
the glass, it will slide off the regulator drive arm.
Flex-drive regulators may be detached the same way
or by removing one screw holding the flex rack to the
lift plate drive arm.
WIRING VOLTAGE TEST
The following wiring test determines whether or
not voltage is continuous through the body harness
to switch. After removing switch for testing purposes, care-
fully separate multiple terminal block on wiring har-
ness from switch body. With ignition switch ON
connect one lead of test light to black (or gray) wire
terminal and touch other test light lead to tan wire
terminal. If the test light comes on, the wiring cir-
cuit between the battery and switch is functional. If
light does not come on, check 30 amp main fuse (cir- cuit breaker) or for a broken wire. For wiring, spe-
cific connector type and location, refer to Group 8W,
Wiring Diagrams.
WINDOW LIFT SWITCH TEST
For switch testing, remove the switch from its
mounting. Using an ohmmeter, refer to Window
Switch Continuity Charts to determine if continuity
is correct. If the results are not obtained, replace the
switch. AC and AY Bodies are equipped with an Auto-
Down feature. This feature allows the operator to
lower the driver's window without having to hold the
switch in the down position. The Auto-Down feature
can be activated by pressing the down switch past
the first detent (Stop). To test the auto-down feature, operate the window
in the normal up and down mode. If the window
works correctly in the normal mode, but not in the
auto-down mode, replace the switch. To test the window switch (other than Auto-Down
mode), install a known good switch.
WINDOW LIFT MOTOR TEST
(1) Connect positive (+) lead from a test battery to
either of the two motor terminals. (2) Connect negative (-) lead from test battery to
remaining motor terminal. (3) The motor should now rotate in one direction to
either move window up or down. (a) If window happens to already be in full UP
position and motor is connected so as to rotate in
UP direction no movement will be observed. (b) Likewise, motor connected to DOWN direc-
tion rotation, no movement will be observed if win-
dow is already in full DOWN position.

GENERAL INFORMATION
Electrically operated power mirrors are available
on all car lines. The mirrors are controlled by a sin-
gle switch assembly located either on the driver's
door trim panel or on the center console. There are three types of switches currently used,
each use s a L (left) R (right) for mirror selection (Fig.
1). Type I, which uses a rocker for mirror selection
and four buttons for mirror movement direction.
Type II, uses a toggle switch which is rotated clock-
wise for the Right mirror or counterclockwise for the
Left mirror selection, and moved UP, DOWN, LEFT,
or RIGHT for mirror movement direction. Type III, uses a paddle knob which is moved Left or Right for
mirror selection and four buttons for mirror move-
ment direction.
The motors which operate the mirrors are part of
the mirror assembly and cannot be replaced sepa-
rately. All vehicles are equipped with an Ignition-Off
Draw Connector which is used when the vehicles are
originally shipped from the factory. This connector,
which is located near the battery, helps to prevent
battery discharge during storage. For specific connec-
tor type and location, refer Group 8W, Wiring Dia-
grams.
