COMBINATION METER ASSEMBLY
CHASSIS ELECTRICAL54A-51
INSPECTION PROCEDURE 5: Engine Coolant Temperature Gauge does not Work (the other meters
work).
TECHNICAL DESCRIPTION (COMMENT)
If only the engine coolant temperature gauge does
not operate, the combination meter, the wiring
harness or its connector may be defective.
TROUBLESHOOTING HINTS
•Malfunction of the engine coolant temperature
gauge unit
•The wiring harness or connectors may have
loose, corroded, or damaged terminals, or
terminals pushed back in the connector.
•Malfunction of the combination meter.
DIAGNOSIS PROCEDURE
STEP 1. Check the engine coolant temperature
gauge unit.
Check to see that the engine coolant temperature
gauge unit operate normally. Refer to P.54A-61.
Q: Is the engine coolant temperature gauge unit
normal?
YES :
Go to Step 2.
NO : Replace the fuel gauge unit. Then go to step
4.

CHASSIS ELECTRICAL54A-61
NOTE: For tachometer check, use an external
high quality inductive tachometer.
2. Compare the readings of the vehicle tachometer
and the external tachometer at every engine
speed, and check if the variations are within the
standard values.
Standard values:
FUEL TANK GAUGE UNIT CHECKM1543001200461
Remove the fuel tank gauge unit. (Refer to GROUP
13C, Fuel Tank P.13C-4.)
FUEL TANK GAUGE UNIT RESISTANCE
1. Check that resistance value between the fuel
gauge terminal and earth terminal is at the
standard value when the fuel tank gauge unit float
is between position "F" (highest) and position "E"
(lowest).
Standard values:
2. Check that resistance value changes smoothly
when the float moves slowly between position "F"
(highest) and position "E" (lowest).
3. If all checks are correct, go to fuel tank gauge unit
float height check. If any check is not correct,
replace the fuel tank gauge unit.
FUEL TANK GAUGE UNIT FLOAT HEIGHT
1. Move the float and measure height A at position
"F" (highest) and B at position "E" (lowest) with
the float arm touching stopper.
Standard values:
2. If all checks are correct, go to fuel tank gauge unit
float height check. If any check is not correct,
replace the fuel tank gauge unit.

VEHICLE SPEED SENSOR CHECK
1. Remove the vehicle speed sensor and connect a
3 − 10 kiloohms resistor as shown in the
illustration.
2. Turn the shaft of the vehicle speed sensor and
check that there is voltage between terminals 2 −
3. (1 turn = 4 pulses)
3. If within the standard value, the vehicle speed
sensor is OK.
If not within the standard value, replace the
vehicle speed sensor.

HEADLAMP
SERVICE SPECIFICATIONSM1542000300332
TROUBLESHOOTING M1542000701281
Features the headlamp automatic shutdown function
to avoid battery drain when the headlamps are left
on. The main features are as follows:
•Extinguishes automatically in three minutes if the
ignition switch is turned off with the lighting switch
on.
•Extinguishes in one second if the driver's door is
opened within that 3-minute period.
•If the headlamps are turned on with the ignition
switch off, the headlamps and tail lamps will
extinguish in three minutes after the driver's door
is opened or closed.
The headlamps are controlled by the Smart Wiring
System (SWS). For troubleshooting, refer to
respective Groups below.
•Not using SWS monitor: GROUP 54B, SWS
Troubleshooting P.54B-38.
•Using SWS monitor: GROUP 54C, SWS
Troubleshooting P.54C-22.

HEADLAMP AIMING
M1542000900538
PRE-AIMING INSTRUCTIONS
1. Inspect for badly rusted or faulty headlamp
assemblies.
2. These conditions must be corrected before a
satisfactory adjustment can be made.
3. Inspect tyre inflation, and adjust if it is necessary.
4. If the fuel tank is not full, place a weight in luggage
room of the vehicle to simulate weight of a full
tank (0.8 kg per litre).
5. There should be no other load in the vehicle other
than driver or substituted weight of approximately
75 kg placed in driver's position.
6. Thoroughly clean the headlamp lenses.7. Place the vehicle on a level floor, perpendicular to
a flat screen 10 m away from the bulb
centre-marks on the headlamp lens.
8. Rock vehicle sideways to allow vehicle to assume
its normal position.
9. Bounce the front suspension through three (3)
oscillations by applying the body weight to hood
or bumper.
10.Four lines of adhesive tape (or equivalent
markings) are required on screen or wall:
(1) Position a vertical tape or mark so that it is
aligned with the vehicle centre line.
(2) Measure the distance from the centre-marks
on the headlamp lens to the floor. Transfer the
measurement to the screen. Horizontal tape or
mark on the screen is for reference of vertical
adjustment. Item Standard value Limit
