< SYMPTOM DIAGNOSIS >

[WITH VDC]

BRC

DOES NOT OPERATE

Description

INFOID:0000000012199746

VDC function, TCS function, ABS function, EBD function and brake limited slip differential (BLSD) function

does not operate.

Diagnosis Procedure

INFOID:0000000012199747

CAUTION:

• VDC function, TCS function, ABS function, EBD function and brake limited slip differential (BLSD)

function never operate when the vehicle speed is 10 km/h (6.2 MPH) or less.

• VDC function and TCS function never operate when VDC OFF switch is operated (when VDC OFF

indicator lamp turns ON).

CHECK WARNING LAMP

Check that ABS warning lamp, brake warning lamp and VDC warning lamp turn ON and turn OFF approx. 1

second after key switch is turned ON. Check that ABS warning lamp, brake warning lamp and VDC warning

lamp and stay in OFF status during driving.

CAUTION:

Brake warning lamp turns ON when parking brake is operated (parking brake switch is ON) or brake

fluid is less than the specified level (brake fluid level switch is ON).
Is the inspection result normal?

YES

>> Normal

>> Perform self-diagnosis for “ABS” with CONSULT.

BRAKE PEDAL VIBRATION OR OPERATION SOUND OCCURS

BRAKE PEDAL VIBRATION OR OPERATION SOUND OCCURS

Description

INFOID:0000000012199748

• Brake pedal vibrates and motor sound from ABS actuator and electric unit (control unit) occurs, when the

engine starts.

• Brake pedal vibrates during braking.

CAUTION:

Vibration may be felt during brake pedal is lightly depressed (just placing a foot on it) in the following

conditions. This is normal.

• When shifting gears

• When driving on slippery road

• During cornering at high speed

• When passing over bumps or grooves [Approx. 50 mm (1.97 in) or more]

• When pulling away just after starting engine [at approx. 10 km/h (6.2 MPH) or higher]

Diagnosis Procedure

INFOID:0000000012199749

SYMPTOM CHECK 1

Check that there are pedal vibrations when the engine is started.
Do vibrations occur?

YES

>> GO TO 2.

>> Check the brake pedal. Refer to

BR-21, "Inspection and Adjustment"

SYMPTOM CHECK 2

Check that motor noise from ABS actuator and electric unit (control unit) occurs when the engine starts.
Does the operation sound occur?

YES

>> GO TO 3.

>> Perform self-diagnosis for “ABS” with CONSULT.

SYMPTOM CHECK 3

Check the symptoms when electrical component (headlamps, etc.) switches are operated.
Does the symptom occur?

YES

>> Check that radio (including wiring), antenna and antenna lead-in wires are not located near ABS

actuator and electric unit (control unit). Move them if they are located near ABS actuator and elec-

tric unit (control unit).

>> Normal

VEHICLE JERKS DURING

BRC

VEHICLE JERKS DURING

Description

INFOID:0000000012199750

The vehicle jerks when VDC function, TCS function, ABS function, EBD function or brake limited slip differen-

tial (BLSD) function operates.

Diagnosis Procedure

INFOID:0000000012199751

CHECK SYMPTOM

Check that the vehicle jerks when VDC function, TCS function, ABS function, EBD function or brake limited

slip differential (BLSD) function operates.
Is the inspection result normal?

YES

>> Normal

>> GO TO 2.

PERFORM SELF-DIAGNOSIS

With CONSULT

Perform self-diagnosis for “ABS”.
Is any DTC detected?

YES

>> Check the DTC. Refer to

BRC-50, "DTC Index"

>> GO TO 3.

CHECK CONNECTOR

With CONSULT

1. Turn the ignition switch OFF.

2. Disconnect ABS actuator and electric unit (control unit) harness connector.

3. Check the connector terminal for deformation, disconnection and looseness.

4. Connect harness connector and perform self-diagnosis for “ABS” again.
Is the inspection result normal?

YES

>> GO TO 4.

>> Poor connection of connector terminal. Repair or replace connector terminal.

CHECK ECM AND TCM SELF-DIAGNOSIS RESULTS

With CONSULT

Perform self-diagnosis for “ENGINE” and “TRANSMISSION” (for CVT models).
Is any DTC detected?

YES

>> Check the DTC.

>> Replace the ABS actuator and electric unit (control unit). Refer to

BRC-153, "Removal and Instal-

lation"

NORMAL OPERATING CONDITION

NORMAL OPERATING CONDITION

Description

INFOID:0000000012199752

Symptom

Result

Brake pedal slightly vibrates and operation sound (motor sound and sound from suspen-
sion) occurs when VDC function, TCS function, ABS function, EBD function or brake limited
differential (BLSD) function operates.

This is not a malfunction, The symptom
occurs VDC function, TCS function, ABS
function, EBD function and brake limited
differential (BLSD) function that are nor-
mally operated.

Brake stopping distance may become longer than models without ABS function depending
on the road conditions, when ABS function is operated on slippery road like rough road,
gravel road or snowy road.

Brake pedal vibrates and operation sound occurs during sudden acceleration and corner-
ing, when VDC function, TCS function or brake limited slip differential (BLSD) function is
operated.

Brake pedal vibrates and motor sound from the engine room occurs, when the engine starts
or the vehicle starts just after starting the engine.

This is not a malfunction, because it is
caused by operation check of ABS actua-
tor and electric unit (control unit).

Acceleration may be felt insufficient depending on the road conditions.

This is not a malfunction, because it is
caused by TCS function that puts the
highest priority to obtain the optimum
traction (stability).

TCS function may operate momentarily, while driving on a road where friction coefficient
varies, or when downshifting, or fully depressing accelerator pedal.

ABS warning lamp and VDC OFF indicator lamp may turn ON, when the vehicle is on a ro-
tating turntable or is given a strong shaking or large vibrations on a ship while the engine is
running.

In this case, restart the engine on a nor-
mal road. If the normal condition is re-
stored, there is no malfunction. In that
case, erase “ABS” self-diagnosis result
memory with CONSULT.

VDC warning lamp may turn ON and VDC function, TCS function and brake limited slip dif-
ferential (BLSD) function may not normally operate, when driving on a special road the is
extremely slanted (bank in a circuit course).

A malfunction in yaw rate/side/decel G sensor system may be detected when the vehicle
sharply turns during a spin turn, acceleration turn or drift driving while VDC function, TCS
function and brake limited slip differential (BLSD) function are OFF (VDC OFF switch is
pressed and VDC OFF indicator lamp is in ON status).

The vehicle speed does not increase, when the accelerator pedal is depressed while the
vehicle is on a 2-wheel chassis dynamometer for speedometer check.

This is not a malfunction. (When checking
the vehicle on a chassis dynamometer,
operate VDC OFF switch so that TCS
function is OFF.)
