ON-VEHICLE SERVICE
SPEEDOMETER CHECKM1543000900423
Adjust the pressure of tyres to the specified level.
(Refer to GROUP 31, On-vehicle Service P.31-7.)
CAUTION
Do not operate the clutch suddenly. Do not
increase/decrease speed rapidly while testing.
1. Set the vehicle onto a speedometer tester and
use wheel chocks to hold the rear wheels.2. To prevent the front wheel from moving from side
to side, attach tension bars to the tie-down hook,
and secure both ends to anchor plates.
3. To prevent the vehicle from moving, attach a chain
or wire to the rear retraction hook, and make sure
the end of the chain or wire is secured.
4. Check if the speedometer indicator range is within
the standard values.
Standard value:
5. If not to the standard value, inspect for proper tyre
size. If not correct, replace the tyres with original
size tyres and retest. If correct, replace the
speedometer. If still not to standard value, replace
the vehicle speed sensor.
TACHOMETER CHECKM1543001000434
1. Attach an external high quality tachometer to the
engine speed detection connector on the harness
side (such as with a paper clip).

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.

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

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

TROUBLESHOOTINGM1542000701292
When the front fog lamp switch is turned to ON with
the tail lamp or the headlamp on (the tail lamp switch
or the headlamp switch is ON), the fog lamp relay
turns on, and the fog lamps will illuminate.
If the tail lamps or the headlamps are turned off with
the lighting switch OFF while the fog lamps are on,
the front fog lamps turn off at the same time to
prevent unattended operation.
If the tail lamps are turned off by the headlamp
automatic shutdown function, the fog lamps turn off
at the same time. However, if the tail lamps illuminate
again, the fog lamps do not.
The front fog lamps are controlled by the Smart
Wiring System (SWS). For troubleshooting, refer to
respective Groups below.
•Not using SWS monitor: GROUP 54B, SWS

FRONT FOG LAMP AIMING CHECKM1542001100438
After setting the vehicles to the following condition,
adjust the front fog lamp aiming.
•Check that the tyre inflation pressure is at the
value indicated on the tyre pressure labels.
•Set the vehicle to the unladen condition and park
it on a level surface.
•Have a single person (approximately 75 kg) sit in
the driver’s seat.•Run the engine at a speed of 2000 r/min to fully
charge the battery.
Turn on the front fog lamps and check that the
illumination is within the standard value range.
Standard value: Illuminates to within 40
metres
CAUTION
For the fog lamp which is not being measured,
disconnect that fog lamp’s connector if possible
so that it does not illuminate while carrying out
the adjustment. Furthermore, make sure that the
light axis does not get shifted when
re-connecting the connector.
If the value is out of the standard value, insert the
screwdriver (+) through the aiming hole on the side
under cover to adjust by turning the adjusting gear
for fog lamp aiming.
NOTE: Horizontal adjustment is not possible.
In addition, the method of checking the light axis on a
screen (simple check) is given below. Item Standard value
