SPEEDOMETER CHECK
(1) Assure tire pressure at standard value. (Refer to GROUP
- Specifications.)
(2)Gt the vehicle on a speedometer tester.
(3)Set free rollers securely on the floor according to the wheel-base and rear tread of the vehicle (when rear wheels
are to be set on free rollers).
(4) Raise the rear wheels on a jack and place rigid racks
to support the specified positions of the side sills (whenrear wheels are to be raised on a jack).
(5) Make sure the parking brake has been set.
cPWD>
(6)Attach anchoring bars on the tie-down brackets and secure
their ends to the anchor plates.(7) Make sure the tension on the right and left bars is the
same. Also be sure there is enough tension on each bar.(8) Attach a chain or wire to the rear tie-down hole. Make
sure the end of the wire or chain is secured firmly.
(9) Take all other necessary precautions.
(1O)Use a speedometer tester to measure the speedometer’s
indication error.

FUEL GAUGE UNIT CHECKTo check, remove fuel gauge unit from fuel tank. (Refer to
GROUP 13F
- Fuel Tank.)
Fuel Gauge Unit Resistance
(1)Check that resistance value between the fuel gauge termi-
nal and ground terminal is at standard value when fuel
gauge unit float is at point F (highest) and point E (lowest).
Standard value:Point F: 3
If: 2 GPoint E: 110
It 7 Q
(2) Check that resistance value changes smoothly when float
moves slowly between point F (highest) and point E (low-
est).Fuel Gauge Unit Float Height
Move float and measure the height at point F (highest) and
point E (lowest) with float arm touching stopper.
Standard value:Point F: 18.6-21.6 mm (.73-.85 in.)
Point E: 193.4-196.4 mm (7.61-7.73 in.)
FUEL SENSOR CHECKConnect fuel gauge unit to battery via test light (12 V-3.4
W). Immerse in water. Condition good if light goes off whenunit thermistor is in water and lights when unit is removed
from water.
CautionwAfter completing this test, wipe the unit dry and install
it in the fuel tank.

OPERATION
0When the lighting switch is placed in the TAILor HEAD position, current flows through the
coil of the tail light relay to the lighting switchand ground, causing the contacts of the tail
light relay to close.
Then current flows through the contacts of thetail light relay to the dedicated fuse
(2) the
individual lights and ground, causing the tail
lights, parking/side marker lights and licenseplate lights to go ON.

lIf the driver’s door is opened after the ignition
switch is turned to “OFF” or the ignition switchis turned to “OFF” after the driver’s door is
opened when the tail lights are lit, the current
which flows to the coil side of the tail light relaywill be cut off by the light automatic shut-off
unit opening the contact point, and the tail light
relay will be turned “OFF’ to automatically shut
off the tail lights, parking and front side marker
lights and license plate light.
lTo turn on the tail lights, parking and front side
marker lights and license plate light again after
they are automatically shut off, turn the lightingswitch to “OFF” once and to “HEAD” again,
or turn the ignition switch to “ACC” or “ON”,
and the automatic shut-OFF will be cancelled
and the current will flow from the light automaticshut-OFF unit to the coil side of the tail light
relay to close the contact point. Thus, the taillight relay will be turned “ON” to turn on the
tail lights, parking and front marker lights and
license plate light.
NOTE
When the lighting switch is at the “HEAD” position,
the light automatic shut-OFF system will be also
activated for the headlights. (Refer to P.54-37.) The
same system will also be activated for the illumina-
tion lights, etc.
TROUBLESHOOTING HINTS1. All lights don’t illuminate.
(1) The headlights don’t illuminate, either.l Check the fusible link (3).
(2) The headlights illuminate.l Check the tail light relay. (Refer to
P.54-108.)l Check the dedicated fuse (2).
l Check the lighting switch. (Refer to
P.54-113.)l Check the light automatic shut-OFF
unit. (Refer to
P.54-108.)2. Some light does not come on.
l Check the bulb.
l Check the grounding circuit.
3. Some light is not automatically shut off.
lCheck the driver’s side door switch.
(Refer to GROUP 42- Door Assembly.)l Check the automatic shut-OFF unit.

P.54-108.)

OPERATION light>l
Battery voltage is always applied to the dome light. When the dome light switch is turned to “ON”,
the dome light will remain lit. After either door is opened if the dome light switch is at “DOOR” position,the dome light will come on.
lWith the dome light turned on (with the ignition switch in the OFF position and with the dome light
switch in the DOOR position), close all doors, and the timer circuit in the ETACS unit will be activatedto gradually vary the voltage for approx. 6 seconds owing to the duty control, and the voltage will
be output to transistor Tr. Since the voltage applied to the dome light gradually decreases, the dome
light will be dimmed.lIf the ignition switch is turned to “ON” while the dome light is lit (while the timer is activated), the
timer circuit will be opened to turn “OFF” transistor Tr. This will immediately turn off the dome light
without dimming. light>-lBattery voltage is always applied to the foot lights and ignition key illumination light.
With the ignition switch in the OFF position, open any door, and all lights will come on.
l
With all lights turned on (with the ignition switch in the OFF position), close all doors, and the timercircuit inside the ETACS unit will operate in the same manner as the dome light to dim all lights.
When the ignition switch is placed in the ON position with all lights turned on (with the timer in operation),the same operation as the dome light will take place.
