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.

PROTECTIVECOVER
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).
3P CONNECTOR
View from wire side
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.

Function Test
NOTE: To test, remove the driver's door panel (see sec-
tion 20), then disconnect all of the connectors from the
ooor panet.
Mifior Test
NOTE: Check the No. 17 {7.5 A) fuse in the under-dashfuse/relay box before testing.
One or both inoperative:
Check for voltage between the BLK//EL terminal and
body ground with the ignition switch ON {ll).There should be battery voltage.
. lf there is no voltage, check for:* Blown No. 17 (7.5 A) fuse in the under-dash
fuse/relay box- An open in the BLK/YEL wire
. lf there is battery voltage, go to step 2.
Check for continuity between the BLK terminal and
body ground.
There should be continuity; check for.* An open in the BLK wire- Poor ground (G501 (sedan), G502)

Connect the BLK,^/EL terminal of the 1OP connector to
the YEVRED1terminal and the YEL /VHT (or YEL/BLK1)
terminal to body ground with iumper wires.
The left mirror should tilt down (or swing left) when you
turn the ignition switch ON (ll).
a lf the mirror does not tilt down (or does not swing lett).check for an open in the YEL/WHT {or YEL/BLKr}wire between the left mirror and the switch. lf the wireis OK, check the lett mirror actuaror.
a lf the mirror neither tilts down nor swings left, repair
the YEL/REDr wire between the letr mirror and theswtlcn.
a lf the mirror operates properly, check the mirror
swttcn.
Right mirrol inoperative:
Connect the BLK/YEL terminal of the 10P connector to
the BLU,^/VHT terminal and the YELMHT {or BLU/BLK)
terminal to body ground with jumper wires.
The right mirror should tilt down (or swing left) whenyou turn the ignition switch ON (ll).
a lf the mirror does not tilt down (or does not swing left),
remove the right door panel and check for an open in
the YEL/WHT (or BLU/BLK) wire between the right mir-
ror and the switch. lf the wire is OK, check the right
mirror actuator.
a lf the mirror neither tilts down nor swings lett, repair

Power Mirrors
- How the Gircuit Works
The two outside mirrors are controlled by the power
minor switch. Each mirror has two reversible
motors: one motor moves the mirror uo and down
and the other motor moves the mirror left and right.
The oower mirror switch contains three switches lo
control mirror direction, and two switches to select
the left or right mirror. With the ignition in ON (ll),
battery voltage is supplied to the power mirror
switch. The mirror selector switch directs voltage
from two of the direction switches to either the left
or the right minor. Each direction switch is used for
more than one function.
Mirror Up Operation
With the power mirror switch in the up position,
switch 1 is moved to the A oosition. Switch 1
applies battery voltage to both the left and right
power mirror up/down motors. lf the mirror selector
switch is in the left position, the left up/down motor
is grounded through the mirror selector switch and
switch 2 in the B position to G501 (Sedan) or G502
(Hatchback). lf the right mirror up/down motor is
selected il is also grounded through switch 2 in the
B position.
Mirror Down Operation
With the power mirror switch in the down position,
switches 2 and 3 are moved to the A position.
Switch 2 applies battery voltage to the left or right
power mirror up/down motor as determined by the
mirror selector switch. The selected mirror motor is
grounded through switch I in the B position to G501
(Sedan) or G502 (Hatchback). When switch 2 is
moved to position A, it also applies battery voltage
to the selected mirror lefyright motor. With switch 3
in the A position, battery voltage is supplied to both
sides of the leruright motor so it does not move.
Mirror Left Operation
With the power mirror switch in the left position,
switches 1 and ? ate moved to the A oosition.
Switch 2 applies battery voltage to the left or right
power mirror lefvright motor as determined by the
mirror selector switch. The selected mirror motor is
grounded through switch 3 in the B position to G501
(Sedan) or G502 (Hatchback). When switch 2 is
moved to position A, it also applies battery voltage
to the selected mirror up/down molor. With switch 1
in the A position, battery voltage is supplied to both
sides of the uD/down motor so it does not move.
Mirror Right Operation
With the power mirror switch in the right position,
switch 3 is moved to the A position. Switch 3
applies battery voltage through the mirror selector
switch to the left or right lefvright motor. The
motor is grounded through the mirror selector
switch and switch 2 in the B oosition to G501
(Sedan) or G502 (Hatchback).
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
