GENERAL INFORMATION
AA-BODY
The Illuminated Entry System (on AA Body) actu-
ates the interior courtesy and/or dome lamps (except
for the illuminated ignition switch) by lifting either
front door exterior handle. Lamp illumination is terminated 35 seconds ( 68
seconds later when battery voltage is normal), or by
turning the ignition switch to the run position,
whichever occurs first. When testing the system, all
vehicle doors must be closed to prevent the door jam
switches from activating the courtesy/dome lamps. Front door handle switches (Fig. 1), and the Illumi-
nated Entry Module (located behind and above the
glove box (Fig. 2) are used to control the system.
Depending on vehicle options, as many as six dif-
ferent electrical components/relays are located above
the glove box. The Illuminated Entry Module will be
the one mounted the closest to the outside of the in-
strument panel. The Module bracket is also used to
commonly mount the Power Door Lock Inhibitor Re-
lay, if equipped. Service procedures for door related components can
be found in Group 23, Body.
AC, AG, AJ OR AY BODY
The Illuminated Entry System (AC, AG, AJ or AY
Body) actuates the interior courtesy and/or dome lamps (except illuminated ignition switch) by lifting
either front door exterior handle. Activation can also
be accomplished with the remote keyless entry sys-
tems hand held module, if equipped. Lamp illumination is terminated 30 seconds ( 62
seconds) later, or by turning the ignition switch to
the run position, whichever occurs first. When test-
ing this system, all vehicle doors must be closed to
prevent the operation of the courtesy/dome lamps. Front door handle switches (Fig. 1), and the Body
Controller (Fig . 3 ) are used to control the system.
Service procedures for door related components can
be found in Group 23, Body.

from 5 Amp fuse in cavity 8 of the black connector.
Also affected would be the body computer, instru-
ment cluster and message center. (3) Be sure that the module has a ground from the
right side cowl behind the body computer to the cav-
ity 5 of the black connector. (4) Be sure that you are supplying a good ground
to the programming wire. (5) If the above circuits are good, replace the Re-
ceiver Module. CONDITION: Doors can be locked or unlocked with
the Keyless Entry transmitter. But the doors will not
lock. The Vehicle Theft Alarm system will not arm,
when using only the power door LOCK switch in the
driver's door. (1) Be sure you have not left key in the ignition
column lock cylinder. (2) If step 1 is OK, check the Key in Lock switch
circuit in the steering column for a short to ground. (3) In this problem the body computer controls the
LOCK function. Be sure that it is providing a battery
voltage output to the door lock relay. The door lock
relay controls the door lock motors. CONDITION: Doors will lock but Vehicle Theft
System will not arm when using the transmitter. (1) The Keyless Entry Receiver Module controls
the door lock signal to the door lock relay. The door
lock relay controls the door lock motors. Check for
battery voltage at cavity 10 of the Theft Alarm mod-
ule from the Receiver module. (2) If voltage is OK, replace Receiver module.
CONDITION: All doors except driver's door will
lock with the transmitter. (1) Test the driver's door output of the Receiver
Module for a ground. (2) If there is no ground at the pin, replace the Re-
ceiver module. (3) If there is a ground at the output, replace the
door lock motor. CONDITION: Only driver's door will lock with the
transmitter.
² Repair ground circuit to unlock relay
² Replace unlock relay
CONDITION: Doors do not lock with the transmit-
ter, but still get horn CHIRP that indicates that they
did lock. Replace Receiver module. CONDITION: Doors will lock with the transmitter
but there is no horn CHIRP. (1) Press horn button, listen horn sound.
(2) If the horn sounded, change horn relay. (3) Still no CHIRP, check continuity between the
horn relay and the receiver output pin. Repair as
necessary. (4) Still no horn CHIRP, replace the receiver mod-
ule. (5) If using a DRB II, refer to Body Diagnostic Pro-
cedures.

DOOR LOCK INHIBIT
The power door lock inhibit system prevents the
doors from being locked using the power door locks
when either of two conditions occur: (1) The key is in the ignition switch and any of the
doors are open. The ignition switch does not have to
be ON. (2) The key is in the ignition switch and the head-
lamp are on.
AC, AG, AJ AND AY BODIES
With the ignition switch in the ON or OFF position
and the driver's door open the Body Controller will
ignore the command to lock the power door locks.
Once the key is removed, or the driver's door is
closed, the Body Controller will allow the power door
locks to lock. Refer to Body Diagnostic Procedure
Manual for further testing procedures.
8P - 6 POWER LOCKS Ä

AA BODY
Uses a power door lock inhibit relay. The relay is
located above the glove box compartment.
INHIBIT RELAY
(1) Using a voltmeter, test for battery voltage at
pin 4. If no voltage check fuse 15 (Fig. 13). (2) Using a ohmmeter, check for continuity to
ground at pin 8. If no continuity to ground, check in-
strument panel ground. (3) To check pin 5:(a) The key is in the ignition switch and a door
is open. (b) The key is in the ignition switch and the
headlamps are ON. (c) Test for continuity to ground.
(d) If not, the relay contact is open or the relay is
being energized when it should not be. Pin 5 feeds
the ground from the relay to door lock switch.
(4) To check pin 6: (a) The key is in the ignition switch and a door
is open. (b) The key is in the ignition switch and the
headlamps are ON. (c) Test for continuity to ground.
(d) If not, check key in switch, headlamps on
switch and/or door jamb switches. Pin 6, feeds
ground from key in switch to the relay.

(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
