NORMAL OPERATING CONDITION
NORMAL OPERATING CONDITION
DescriptionINFOID:0000000003767029
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 a 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 G sensor system, when the vehicle turns sharply, such as dur-
ing a spin turn, axle turn, or drift driving, while the VDC function is off (VDC OFF indicator lamp illuminated).
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
Be careful with the following when removing sensor.
CAUTION:
 Do not twist sensor harness as much as possible, when removing it. Pull sensors out without pulling
sensor harness.
 Be careful to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before remov-
ing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor function.
INSTALLATION
Be careful with the following when installing wheel sensor. Tighten installation bolts to the specified torques.
Refer to BRC-151, "
FRONT WHEEL SENSOR : Exploded View".
CAUTION:
 When installing, make sure there is no foreign material such as iron chips on and in the mounting
hole of the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove
any foreign material and clean the mount.

 Completely push in rubber grommets of strut bracket and body bracket until they lock when install-
ing wheel sensor so that the wheel sensor harness will not be twisted. Install grommet groove onto
bracket with orange line on the harness facing bracket opening (mounting hole). There should be no
twists in the harness when installed.

 To remove brake tube, use a flare nut wrench to prevent flare nuts and brake tube from being dam-
aged. To install, use flare nut crowfoot and torque wrench.
 Do not apply excessive impact to ABS actuator and electric unit (control unit), such as dropping it.
 Do not remove and install actuator by holding harness.
 After work is completed, bleed air from brake tube. Refer to BR-10, "
Bleeding Brake System".
 After installing harness connector in the ABS actuator and electric unit (control unit), make sure
connector is securely locked.
 When replacing ABS actuator and electric unit (control unit), make sure to adjust neutral position of
steering angle sensor. Refer to BRC-66, "
ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL
POSITION : Description".
Install ABS actuator and electric unit (control unit) as per the follow-
ing steps.
1. Temporarily tighten mounting bolt (1) because the bracket (2) is
temporarily being hold.
2. Tighten mounting bolt (3) while holding the bracket.
3. Tighten mounting bolts to the specified torque in the order of (4),
(1).

1.PRELIMINARY INSPECTION
Perform the preliminary inspection. Refer to CHG-20, "
Inspection Procedure".
>> GO TO 2.
2.STOP POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
Stop the operation of the power generation voltage variable control in either of the following procedures.
• After selecting “ENGINE” of “SELECT SYSTEM” using CONSULT-III, set the DUTY value of “ALTERNATOR
DUTY” to 0 % by selecting “ALTERNATOR DUTY” of “Active Test”. Continue “Active Test” until the end of
inspection. (When the DUTY value is 0 or 100 %, the normal power generation is performed according to the
characteristic of the IC regulator of the alternator.)
 Turn the ignition switch OFF, and disconnect the battery current sensor connector. [However, DTC (P1550 -
P1554) of the engine might remain. After finishing the inspection, connect the battery current sensor connec-
tor and erase the self-diagnostic results history of the engine using CONSULT-III.]
>> GO TO 3.
3.INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS ON)
Turn the ignition switch ON.
Does the charge warning lamp illuminate?
YES >> GO TO 4.
NO >> GO TO 11.
4.INSPECTION WITH CHARGE WARNING LAMP (IDLING)
Start the engine and run it at idle.
Does the charge warning lamp turn OFF?
YES >> GO TO 5.
NO >> GO TO 6.
5.INSPECTION WITH CHARGE WARNING LAMP (ENGINE AT 2,500 RPM)
Increase and maintain the engine speed at 2,500 rpm.
Does the charge warning lamp illuminate?
YES >> GO TO 8.
NO >> INSPECTION END
6.“L” TERMINAL CIRCUIT (SHORT) INSPECTION
Check “L” terminal circuit (short). Refer to CHG-12, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 7.
NO >> Repair as needed.
7.“S” TERMINAL CIRCUIT INSPECTION
Check “S” terminal circuit. Refer to CHG-13, "
