Refer to 8W, Wiring Diagrams. (c) If there is voltage or ground, check cluster for
distorted terminals. If terminals are OK, replace
printed circuit board.
(3) When testing the temperature gauge, allow the
engine to run until the vehicle reaches a normal op-
erating temperature. Turn ignition OFF and remove
gauge from cluster.
² When checking the temperature and oil pressure
gauges, it is important to have the same engine tem-
perature and engine speed when noting gauge posi-
tion.
² The time between gauge position reading and
sending unit measuring should be kept to a mini-
mum.
² When testing oil pressure gauge, engine needs to
be running. (a) Measure and record the resistance between
sending unit pin and ground pin of the gauge in
question. Refer to Gauge Calibration.

(f) If everything checks out OK, refer to Sending
Unit Test.
(4) With the ignition switch in the ON position,
check for battery voltage across the ignition pin and
the ground pin. (5) If fuel gauge meets specifications check fuel
tank and original fuel tank sending unit as follows: (a) Carefully remove fuel tank sending unit from
tank. (b) Refer to sending unit removal Group 14,
Fuel. (c) Connect sending unit wire and jumper wire
as described in the test procedure.
(6) If fuel gauge now checks within specifications,
original sending unit is electrically okay, check fol-
lowing as a possible cause: (a) Ground wire from sending unit to left side
cowl for continuity. (b) Sending unit deformed. Make sure sending
unit float arm moves freely and pick up tube is not
bent upwards creating an interference with bottom
of tank and inspect float. (c) Sending unit improperly installed. Install
properly. (d) Mounting flange on fuel tank for sending
unit deformed. Feel for interference fit of sending
unit to bottom of tank. It is permissible to bend
pick up tube down a little near mounting flange to
gain interference fit. (e) Fuel tank bottom deformed, causing improper
positioning of sending unit pick up tube. Replace or
repair tank and recheck sending unit.GAUGE CALIBRATION
(1) Remove the gauge.
(2) Check for ignition voltage and ground to the
gauge. (3) With the ignition key in the OFF position, re-
place gauge. Turn the ignition key to the ON posi-
tion. To test oil pressure gauge engine must be
running. When testing oil or temperature gauge the
engine should be at normal operating temperature.
Record the gauge position. (4) Remove gauge and record the resistance be-
tween the sending unit pin and the gauge ground
pin. When checking gauges, it is important to have
the same engine temperature and speed when noting
gauge position. The time between gauge reading and
measuring should be kept to a minimum. (5) Resistance Chart (Fig. 11), is general guide-
lines for checking the gauge position against the
sending unit resistance. Because of only a few specific points of gauge posi-
tion versus sending unit resistance, a good estimate
is needed when the resistance falls between gradua-
tions. Even when the resistance corresponds to grad-
uations, the gauge has a tolerance of 64 ohms.
Volt gauge: The calibration dot on the volt gauge
corresponds to 13 volts between the gauge ignition
and ground pins. If voltage varies from this, estimate
proper gauge position with input voltage.
FUEL GAUGE REPLACEMENT
(1) Remove instrument cluster bezel.
(2) Remove mask and lens.
(3) If equipped with tachometer, remove three re-
taining screws and pull the tach straight back.

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 OF DEPLOYED AIR BAG MODULE
After an air bag has been deployed, the air bag
module and clockspring must be replaced because
they cannot be reused. Other air bag system compo-
nents are replaced if damaged.
SCHEDULED MAINTENANCE INSPECTION
Vehicles equipped with a Air Bag System must be
inspected every three years or 30,000 miles / 48,000
Km. The following items should be inspected. (1) Inspect components for damage or deteriora-
tion. (a) If the air bag module housing shows signs of
physical damage or abuse, replace the module. (b) Check that both front impact sensors are
properly installed to the upper crossmember of the
radiator closure panel. Repair as required.
(2) Check the air bag warning lamp for proper op-
eration as follows: (a) Turn ignition switch to the ON position, the
air bag warning lamp should light. If not, test the system using the DRB II and Passive Restraint
System Diagnostic Procedures Manual. Repair as
required.
(b) The air bag warning lamp lights, but fails to go
out after ten seconds. Test the system using the DRB
II and Passive Restraint System Diagnostic Proce-
dures Manual. Repair as required. (c) Erasing of fault codes is not required.
AIR BAG SYSTEM CHECK
WARNING: BEFORE BEGINNING ANY AIR BAG SYS-
TEM CHECK PROCEDURES, REMOVE AND ISOLATE
THE BATTERY NEGATIVE (-) CABLE (GROUND)
FROM THE VEHICLE BATTERY. THIS IS THE ONLY
SURE WAY TO DISABLE THE AIR BAG SYSTEM.
FAILURE TO DO THIS COULD RESULT IN ACCIDEN-
TAL AIR BAG DEPLOYMENT AND POSSIBLE PER-
SONAL INJURY.
WHEN AN UNDEPLOYED AIR BAG ASSEMBLY IS
TO BE REMOVED FROM THE STEERING WHEEL,
DISCONNECT BATTERY GROUND CABLE AND
ISOLATE. ALLOW SYSTEM CAPACITOR TO DIS-
CHARGE FOR TWO MINUTES, THEN BEGIN AIR
BAG REMOVAL. (1) Disconnect the battery negative cable and iso-
late. (2) Remove forward console or cover as necessary.
(3) Connect DRB II to ASDM diagnostic 6-way con-
nector, located at right side of module. (4) Turn the ignition key to ON position. Exit vehicle
with DRB II. Use the latest version of the proper
cartridge. (5) After checking that no one is inside the vehicle,
connect the negative battery cable. (6) Using the DRB II, read and record active fault
data. (7) Read and record any stored faults.
(8) Refer to the Passive Restraint Diagnostic Test
Manual if any faults are found in steps 6 and 7. (9) Erase stored faults if there are no active fault
codes. If problems remain, fault codes will not erase. (10) With the ignition key in the ON position, make
sure no one is in the vehicle. (11) From the passenger side of vehicle, turn the
ignition key to OFF then ON and observe the instru-
ment cluster air bag lamp. It should go on for 6 to 8
seconds, then go out; indicating system is functioning
normally. If air bag warning lamp either fails to light,
blinks on and off or goes on and stays on, there is
a system malfunction. Refer to the Passive Re-
straint Diagnostic Test Manual to diagnose the
problem.

GENERAL INFORMATION
All doors can be locked or unlocked electrically by
operating the switch on a front door panel or arm
rest. The rear doors can be locked or unlocked by actu-
ation of the front door switch, or can be locked or un-
locked mechanically and independently with their
respective locking knobs. The front doors can be locked or unlocked mechan-
ically with the locking knob regardless of electrical
locking and unlocking actuation with the front door
knobs. The right and left front door on all car lines can be
locked or unlocked mechanically from the outside
with the key or electrically as described above. The
left front can also be unlocked by actuation of the in-
side remote door handle. The right front door on AC,
AG, AJ and AY can be unlocked by actuation of the
inside remote door handle. The deck lid lock consists of a latch with internal
solenoid and push button switch. The solenoid is en-
ergized only when the push button is depressed.
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.
KEYLESS ENTRY SYSTEM
The system allows locking and unlocking of vehicle
door(s) and Trunk lid by remote control using a hand
held radio transmitter. The ignition switch must be
OFF before the trunk lid can be unlocked with the
transmitter. The receiver may receive signals from two trans-
mitters. Each transmitter has its own code, and the
code has been stored in memory. If the transmitter is
replaced or a second transmitter is add, the code on
both units have to be placed in memory.
CIRCUIT BREAKER TEST
Find correct circuit breaker on fuse block. Pull out
slightly but be sure that circuit breaker terminals
still contact terminals in fuse block. Connect ground
wire of voltmeter to a good ground. With probe of
voltmeter positive wire, check both terminals of cir-
cuit breaker for 12 volts. If only one terminal checks
at 12 volts, circuit breaker is defective and must be
replaced. If neither terminal shows 12 volts, check
for open or shorted circuit to circuit breaker.
WIRING VOLTAGE TEST
The following wiring test sequence determines
whether or not voltage is continuous through the
body harness to switch. (1) Remove left side switch from trim panel.
(2) Carefully separate multiple terminal block on
wiring harness from switch body. (3) Connect one lead of test light to a ground ter-
minal:
² Black Wire AA and AC Bodies
² Gray wire AG and AJ Bodies
² Touch other test light lead to Red Wire terminal.
² If test light comes on, the wiring circuit between
the battery and switch is functional.
² If test light does not come on, check 30 amp circuit
breaker or for a open circuit.
SWITCH TEST
Remove the switch from its mounting location. Us-
ing an ohmmeter, refer to (Fig. 1) to determine if
continuity is correct in the Lock and Unlock switch
positions. If these results are not obtained, replace
the switch.
