NOTE: For information on tyre inflation pressure,
refer to the label attached to the centre pillar on the
driver's side.
TYRE WEAR CHECKM1311001000334
Measure the tread depth of the tyres.
Minimum limit: 1.6 mm
If the remaining tread depth is less than the minimum
limit, replace the tyre.
NOTE: When the tread depth of the tyres is reduced
to 1.6 mm or less, wear indicators will appear.
WHEEL RUNOUT CHECKM1311001100353
Jack up the vehicle so that the wheels are clear of
the floor. While slowly turning the wheel, measure
wheel runout with a dial indicator.
Limit:
If wheel runout exceeds the limit, replace the wheel.

COMBINATION METER ASSEMBLY
CHASSIS ELECTRICAL54A-60
STEP 9. Check the wiring harness between
combination meter connector C-04 (terminal 1
and 2) and earth.
Q: Are the wiring harness between combination meter
connector C-04 (terminal 1 and 2) and earth in
good condition?
YES :
This procedure is complete.
NO : Repair or replace the wiring harness. Check
to see that all meters operate.
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).

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
