Side Structure Reinforcement
1. The thickness of the reinforcements of the front pillar and center pillar has been increased to improve
collision safety.
2. The front pillar reinforcement upper, side outer panel, and front roof rail have been joined to improve
twisting rigidity.
3. The side sill has been made thin by employing a variable thickness steel sheet* for the center pillar
reinforcement to improve safety in collision and realize lightweight.
4. The cross section of the side sill outer reinforcement has been made large to improve safety in
collision and body rigidity.
5. A rear pillar reinforcement has been added, and the rear shelf and rear wheel house have been
joined to improve the twisting rigidity of the suspension attaching portion.

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)
Excessive vibration or concentricity of
the axle hubReplace the hub
(
minimum amplitude of 100 mV)4WD-ECU earth faultCorrect
Noise in the waveform or waveform
ibl
Open circuit of the sensorReplace the sensor
is abnormalOpen circuit of the harnessReplace the harness
Wheel speed sensor installation faultCorrect the installation of the sensor
Chipping or flattening of the ABS rotorReplace the ABS rotor
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.
