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)
Excessive vibration or concentricity of
the axle hubReplace the hub

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.

TROUBLESHOOTING
BASIC TROUBLESHOOTING CONDITIONS
Refer to GROUP 00 – How to Use Troubleshooting/Inspection Service Points.
NOTE
Before starting the troubleshooting procedure, make sure that the following items have been checked
okay.
DThe correct steering wheel has been properly installed in the neutral position of the steering column
shaft.
DTire and wheel sizes are correct with correct specifications. Inflation pressure, balance, and wear
conditions are okay.
DWheel alignment is correct.
DThe engine, suspension, and other parts have not been remodeled so as to affect the AYC system.
DIAGNOSIS FUNCTION
READING THE DIAGNOSIS CODES
Read the diagnosis code using MUT-IIor ACD mode indicator
lamp. (Refer to GROUP 00 – How to Use Troubleshooting/
Inspection Service Points.)
NOTE
Connect the MUT-IIto the 16-pin diagnosis connector.

ON-VEHICLE SERVICE
WHEEL ALIGNMENT CHECK AND
ADJUSTMENT
Measure the wheel alignment with the vehicle parked on a
level surface.
The front suspension, steering system, and wheels should be
serviced to normal condition prior to measurement of wheel
alignment.
TOE-IN
Standard value:
At the centre of tyre tread 0±2mm
Toe angle (per wheel) 0_00’±05’
1. Adjust the toe-in by undoing the clip and lock nut, and
turning the left and right tie rod turnbuckles by the same
amount (in opposite directions).
NOTE
The toe will move out as the left turnbuckle is turned
toward the front of the vehicle and the right turnbuckle
is turned toward the rear of the vehicle.
2. Install the clip and tighten the lock nut to the specified torque.

Caution
Because the wheel speed sensor cables move together with the front and rear suspension, they
vibrate greatly when driving over poor road surfaces. As a result, the sensor harnesses should also
be shaken when monitoring of output waveforms of the wheel speed sensors in order to simulate
conditions such as driving over poor road surfaces.
HYDRAULIC UNIT CHECK
1. Jack up the vehicle and support the vehicle with rigid racks placed at the specified jack-up points
or place the wheels which are checked on the rollers of the braking force tester.
Caution
(1) The roller of the braking force tester and the tyre should be dry during testing.
(2) When testing the front brakes, apply the parking brake, and when testing the rear brakes,
stop the front wheels by chocking them.
2. Turn the ignition key to the “LOCK” (OFF) position and set the MUT-II.
Caution
Turn the ignition key to the “LOCK” (OFF) position before connecting or disconnecting the
MUT-II.
3. After checking that the shift lever is in neutral, start the engine.
4. Use the MUT-IIto force-drive the actuator.
NOTE
(1) During the actuator test, the ABS warning lamp will illuminate and the anti-skid control will be
cancelled.
(2) When the ABS has been interrupted by the fail-safe function, the MUT-IIactuator testing cannot
be carried out.
5. Turn the wheel by hand and check the change in braking force when the brake pedal is depressed.
When using the braking force tester, depress the brake pedal until the braking force is at the following
values, and check that the braking force decreases when the actuator is force-driven.
