INSPECTION SERVICE POINTS FOR A BLOWN
FUSE
Remove the blown fuse and measure the resistance between
the load side of the blown fuse and the earth. Set the switches
of all circuits which are connected to this fuse to a condition
of continuity. If the resistance is almost 0Ωat this time,
there is a short somewhere between these switches and the
load. If the resistance is not 0Ω, there is no short at the
present time, but a momentary short has probably caused
the fuse to blow.
The main causes of a short circuit are the following.
DHarness being clamped by the vehicle body
DDamage to the outer casing of the harness due to wear
or heat
DWater getting into the connector or circuitry
DHuman error (mistakenly shorting a circuit, etc.)
POINTS TO NOTE FOR INTERMITTENT
MALFUNCTIONS
Intermittent malfunctions often occur under certain conditions,
and if these conditions can be ascertained, determining the
cause becomes simple. In order to ascertain the conditions
under which an intermittent malfunction occurs, first ask the
customer for details about the driving conditions, weather
conditions, frequency of occurrence and trouble symptoms,
and then try to recreate the trouble symptoms. Next, ascertain
whether the reason why the trouble symptom occurred under
these conditions is due to vibration, temperature or some
other factor. If vibration is thought to be the cause, carry
out the following checks with the connectors and components
to confirm whether the trouble symptom occurs.
The objects to be checked are connectors and components
which are indicated by inspection procedures or given as
probable causes (which generates diagnosis codes or trouble
symptoms.)
DGently shake the connector up, down and to the left and
right.
DGently shake the wiring harness up, down and to the
left and right. Check the branch point of wiring harness
connector closely.
DGently rock each sensor and relay, etc. by hand.
DGently shake the wiring harness at suspensions and other
moving parts.
NOTE
If determining the cause is difficult, the flight recorder function
of the MUT-IIcan also be used.

GENERAL -Support Locations for Lifting and Jacking00-26
PLATE TYPE LIFT
To avoid damaging the side sill garnish, put a wooden block between the side sill and a lift.
NOTE
The wooden block should be 100 mm wide and 50 mm high.
SUPPORT POSITIONS AND SUPPORT METHOD
FOR AN H-BAR LIFT
Caution
When service procedures require removing the rear
suspension, fuel tank, spare tyre and rear bumper, place
additional weight on rear end of vehicle or anchor vehicle
to hoist to prevent tipping of centre of gravity changes.
When H-bar lift is used to lift up vehicles, use of metallic
attachment attached to the H-bar lift may cause damage
to the suspension arm etc. Therefore, lift up the vehicle by
the following procedure.
1. Place the vehicle on the H-bar lift (same direction).
2. Place attachments on the H-bar lift at the designated
chassis-support positions. When making the attachments,
refer to the section concerning making them.
Caution
If support is at any location other than the designated
positions, the body or suspension might be deformed
or otherwise damaged, so care should be taken to
support only at the correct (designated) positions.
3. Raise the H-bar lift to the height at which the vehicle
is slightly raised and check to be sure that the vehicle
is correctly and sufficiently secured; then raise the vehicle.

MANUAL TRANSMISSION - On-vehicle Service22A-45
Output voltage:
Above 70 mV when measured with the circuit
tester
Above 200 mVP-P when measured with the
oscilloscope
4. If the output voltage is lower than the above values, the
following reasons may be suspected. Check or replace
the wheel speed sensor.
DExcessive clearance between the ball piece of the
wheel speed sensor and ABS rotor
DWheel speed sensor faul
INSPECTION PROCEDURE USING OSCILLOSCOPE
After checking the connected state of the harness of the
wheel speed sensor and connector, and measure the output
voltage waveform of each wheel speed sensor on the
oscilloscope as follows.
Start the engine, shift the transmission to the 1st gear to
rotate the driving wheel, and rotate the non-driving wheel
at constant velocity with the hand.
NOTE
1. It is also possible to actually drive the vehicle and observe
the waveform.
2. The output voltage is low if the wheel speed is low and
gradually increases as the speed increases.

PhenomenonProbable causeSolution
Waveform amplitude is too small or
not output at allWheel seed sensor faultReplace the sensor
Excessive waveform amplitude
(However allowed if above the
iilit df100V)

Caution
As the wheel speed sensor cable follows the movement of the front or rear suspension, it will
change considerably on poor condition roads. Therefore, also observe the output voltage waveform
of the wheel speed sensor with the sensor harness vibrated to simulate special conditions such
as driving in poor road conditions.

WHEEL AND TYRE -Troubleshooting31-4
WHEEL BALANCE ACCURACY
PURPOSE
This section contains tips and procedures for
achieving accurate wheel balance. Steering wheel
vibration and /or body shake can result if any of
these procedures are not carefully observed.
1. Wheels and tires must be properly mounted
on a balancer in order to achieve correct
balance. Centering the wheel on the shaft of
the balancer is essential for proper mounting.
2. Off-the-car wheel balancers must be calibrated
periodically to ensure good balancing results.
An inaccurately calibrated balancer could cause
unnecessary replacement of tires, shocks,
suspension components, or steering
components.Check your balancer’s calibration approximately
every 100 balances. Your wheel balancer’s
instruction manual should include calibration
procedures. If the calibration procedures
specifically for your balancer are missing, use the
generic steps in this section for zero calibration,
static balance, and dynamic balance checks. The
wheel balancer calibration checks are also
described in the flowchart. (Refer to P.31-5.)
PROCEDURE
Balancing Tips
1. Confirm that the balancer’s cone and the wheel
mounting cone are undamaged and free of
dirt and rust.
2. On this vehicle the wheel’s center hole on the
hub side has a chamfered edge. Use a
back-mounting cone on your wheel balancer
to center the wheel on the balancer shaft.3. Install a wheel mounting cone. The appropriate
size cone for this vehicle is 67.0 mm.
4. Before balancing the wheel, remove any wheel
weights from both sides. Also check both sides
for any damage.
5. When installing wheel weights, hammer them
at a straight (not diagonal) angle.

Confirming Proper Balance
1. After balancing the wheel, loosen the wing nut
and turn the wheel 180°against the balancer’s
hub. Then retighten the wing nut and check
the balance again. Repeat wheel balance if
necessary.2. Turn the wheel again 180°against the
balancer’s hub. If the wheel becomes
out-of-balance each time it is turned against
the balancer’s hub, the wheel balancer may
require calibration.
Wheel Balancer Calibration Checks
1. Mount an undamaged original-equipment alloy
rim and tire assembly (wheel) onto your
off-the-car wheel balancer. Balance the wheel.2.<>
Loosen the balancer wing nut, rotate the wheel
a half turn (180°), and retighten the nut.
Recheck the balance.
