Fuel Gauge
Gauge Test
NOTE: Refer to page 23-123 for the fuel gauge system
circuit.
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testing.
2. Remove the rear seat (see section 20).
Remove the protective cover and access panel from
the tloor.
With the ignition switch OFF, disconnect the 3p con-nector from the fuel gauge sending unit.

Connect the voltmeter positive probe to the
YEL/WHT terminal and the negative probe to the
BLK/WHT terminal, then turn the ignition switch ON(ll). The.e should be between 5 and 8 V.
a lf the voltage is as specified, go to step 6.a lI the voltage is not as specified, check for- an open in the YEL/WHT, BLU/WHT or
BLK/WHT wire.- poor ground (G501, G502).

6.Turn the ignition switch OFF. Attach a jumper wire
between the BLKMHT and YEL/WHT terminals,
then turn the ignition switch ON {1.,.
Check that the pointer of the fuel gauge starls mov-
ing toward the "F" mark.
CAUTION: Turn the ignition switch OFF before the
pointer reaches "F" on the gauge dial, Failure to do
so may damage the tuel gauge.
NOTE: The fuel gauge is a bobbin (cross-coil) type
gauge, hence the fuel level is continuously indicat-
ed even when the ignition switch is OFF, and thepointer moves more slowlv than that ol a bimetal
rype gauge.
a lf the pointer ol the fuel gauge does not move at
all, replace the gauge.
a It the gauge is OK, inspect the fuel gauge send-
ing unit.

2.
1.Remove the console, then disconnect the 2P con-
nector of the shift lock solenoid trom the main wire
harness.
NOTE: Do not connect power to the B (- ) terminal
(reverse polarity) or you will damage the diode in-
side the solenoid.
Connect battery power to the A terminal, ground the
B terminal momentarily, and check solenoid
operation.
a lf the solenoid does not operate, replace it as
described in steps 3,4, and 5.
a lf the solenoid does operate, check and, i{ neces
sary, adjust its two positions as shown in step 5.
3. Remove the shift lock collar and the solenoid pin.
4. Remove the selfiocking nuts and shift lock solenoid,
then installthe new solenoid in the reverse order of
removal.

Integrated Control Unit
Circuit Diagram
Description
An integrated control unit, located in lhe left kick panel, integrates the lunctions of the key-in/seat belt r€minder , side
marker light llasher, wiper/washer, lights-on reminder, rear window delogger timer, brake system light bulb check, and
engine oil pressure indicator flasher circuits.
NOTE: Different wires with the same color have been given a nu mber suflix to distinguish them (for example,
GRN/RED I and GRN/RED' are not the same).

Headlight
Adjustment
Befole adiusting the headlights:
a Park the car on level ground.
a Make sure the fuel tank is full.
The driver or someone who weighs the same should
sit in the driver's seat.
Load the trunk with the items you usually carry (if you
usually pull a trailer, attach jt to the car).
Push down on the front and rear bumpers several
times to make sure the car is sitting normally.
When installing a new headlight assembly, tighten the
four mounting bolts so that the indicator in the verti-
cal gauge comes to the "O" mark.
HORIZONTAL ANGLEGAUGE
HORIZONTALADJUSTER
'1. Open the hood.
2. Check that both the horizontal and vertical gauge
rcad "O" .
a lf the gauges tead "O", check headlight aiming
with the aiming charts on page 23-171. (lf aiming
isn't correct. refer to the frame repair chart in
section 20).
a lf one or both gauges don't read "O", go to step
23-170
3. Turn the low beams on. lf necessary, align the verti-
cal indicator with its "O" mark by turning the verti-
cal adjuster with a Phillips screwdriver, and check
aiming with the chan on page 23-171.
lf necessary, align the horizontal indicator with its"O" mark by turning the horizontal adjuster with a
Phillips screwdriver, and check aiming with the
chart on page 23-171.
5.Recheck that the vertical indicator bubble is aligned
with "0" t 1.
lf necessary, adjust as described in step 3.
Turn the high beams on and check aiming with the
charts on page 23-171.
