In case of an electrical malfunction with the ABS, the ABS warning lamp, VDC OFF indicator lamp and SLIP
indicator lamp will turn on. In case of an electrical malfunction with the EBD system, the BRAKE warning lamp,
ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp will turn on.
The system will revert to one of the following conditions of the Fail-Safe function.
1. For ABS malfunction, only the EBD is operative and the condition of the vehicle is the same condition of
vehicles without ABS/TCS/VDC system.
2. For EBD malfunction, the EBD and ABS become inoperative, and the condition of the vehicle is the same
as the condition of vehicles without ABS/TCS/VDC or EBD system.
VDC/TCS SYSTEM
In case of TCS/VDC system malfunction, the VDC OFF indicator lamp and SLIP indicator lamp are turned on
and the condition of the vehicle is the same as the condition of vehicles without TCS/VDC system. In case of
an electrical malfunction with the TCS/VDC system, the ABS control continues to operate normally without
TCS/VDC control.

SYMPTOM DIAGNOSIS
ABS
Symptom TableINFOID:0000000001731343
If ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp turn ON, perform self-diagnosis.
NOTE:
 1: The ABS does not operate when the speed is 10 km/h (6 MPH) or less.
 2: Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly depressed. However, this is normal.
- When shifting gears
- When driving on slippery road
- During cornering at high speed
- When passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]
- When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]Symptom Check item Reference

Diagnosis ProcedureINFOID:0000000001731344
1.CHECK START
Check front and rear brake force distribution using a brake tester.
Is the inspection result normal?
YES >> GO TO 2
NO >> Check brake system.
2.CHECK FRONT AND REAR AXLE
Make sure that there is no excessive play in the front and rear axles. Refer to front: FA X - 6 , "
On-Vehicle
Inspection and Service", Rear: RAX-5, "On-Vehicle Inspection and Service".
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair or replace malfunctioning components.
3.CHECK WHEEL SENSOR AND SENSOR ROTOR
Check the following.
 Wheel sensor installation for damage.
 Sensor rotor installation for damage.
 Wheel sensor connector connection.
 Wheel sensor harness inspection.
Is the inspection result normal?
YES >> GO TO 4
NO >>  Replace wheel sensor or sensor rotor. Refer to BRC-83, "
Removal and Installation".
 Repair harness.
4.CHECK ABS WARNING LAMP DISPLAY
Make sure that the ABS warning lamp is turned off after the ignition switch is turned ON or when driving.
Is the ABS warning lamp illuminated?
YES >> Perform self-diagnosis. Refer to BRC-25, "CONSULT-III Function (ABS)".
NO >> Normal

NORMAL OPERATING CONDITION
DescriptionINFOID:0000000001731350
Symptom Result
Slight vibrations are felt on the brake pedal and the operation noises occur, when VDC, TCS or ABS is acti-
vated.
This is a normal condi-
tion due to the VDC,
TCS or ABS activation. Stopping distance is longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
The brake pedal moves and generates noises, when TCS or VDC is activated due to rapid acceleration or
sharp turn.
The brake pedal vibrates and motor operation noises occur from the engine room, after the engine starts and
just after the vehicle starts.This is normal, and it is
caused by the ABS op-
eration check.
Depending on the road conditions, the driver may experience a sluggish feel. This is normal, because
TCS places the highest
priority on the optimum
traction (stability). TCS may activate momentarily if wheel speed changes when driving over location where friction coefficient
varies, when downshifting, or when fully depressing accelerator pedal.
The ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp may turn ON when the vehicle is
subject to strong shaking or large vibration, such as when the vehicle is rotating on a turntable or located on
a ship while the engine is running. In this case, restart the
engine on a normal
road. If the normal con-
dition is restored, there
is no malfunction. At
that time, erase the self-
diagnosis memory. VDC may not operate normally or the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp
may illuminate, when running on a special road that is extremely slanted (e.g. bank in a circuit course).
A malfunction may occur in the yaw rate/side/decel G sensor system, when the vehicle turns sharply, such
as during a spin turn, axle turn, or drift driving, while the VDC function is off (VDC OFF indicator lamp illumi-
nated).
The vehicle speed will not increase even though the accelerator pedal is depressed, when inspecting the
speedometer on a 2-wheel chassis dynamometer. Normal (Deactivate the
VDC/TCS function be-
fore performing an in-
spection on a chassis
dynamometer.)
VDC OFF indicator lamp and SLIP indicator lamp may simultaneously turn on when low tire pressure warn-
ing lamp turns on.This is not a VDC sys-
tem error but results
from characteristic
change of tire.

Removal and InstallationINFOID:0000000001691408
REMOVAL
Be careful of the following.
CAUTION:
 When removing the sensor, do not rotate it if possible, and not forcibly pull the sensor harness.
 Before removing front or rear wheel hub, remove wheel sensor to avoid sensor wiring damage.
INSTALLATION
Be certain to tighten bolts to the specified torque. Be careful of the following:
 Check the inside of the sensor mounting hole for foreign material, the rotor surface for iron chips and other
foreign material, and if anything is non-standard, clean it before installation, or replace it.
 When installing the front sensor, completely push in the strut bracket and body bracket rubber grommets
until they lock so that the sensor harness does not become twisted. In addition, there should be no twists in
the harness when installed. Install the harness so that the painted part faces the outside of the vehicle.
 When installing the rear sensor, completely push in the rubber bracket of the suspension arm bracket and
lock the marking area of the side member harness mount so that the sensor harness will not be twisted. In
addition, there should be no twists in the harness when installed.

Removal and InstallationINFOID:0000000001691409
FRONT
 Because the sensor rotor is integrated with the wheel bearing, replace it together with the wheel bearing
assembly. Refer to FAX-7, "
Removal and Installation".
REAR
 During removal and installation, remove the wheel hub (brake drum). Refer to RAX-6, "Removal and Instal-
lation".
CAUTION:
The sensor rotor is a non-reusable part, it must be replaced by an new part when removing it.
