THE BRAKING DISTANCE IS LONG

THE BRAKING DISTANCE IS LONG

Description

INFOID:0000000010723748

Brake stopping distance is long when ABS function is operated.

Diagnosis Procedure

INFOID:0000000010723749

CAUTION:

Brake stopping distance on slippery road like rough road, gravel road or snowy road may become
longer when ABS is operated than when ABS is not operated.

1.

CHECK BRAKING FORCE

Check the brake force using a brake tester.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Check each components of brake system.

2.

CHECK BRAKE PERFORMANCE

Disconnect the ABS actuator and electric unit (control unit) connector so that ABS does not operate. Check
the brake stopping distance in this condition. Connect harness connectors after checking.

Is the inspection result normal?

YES

>> Normal

NO

>> Check each components of brake system.

DOES NOT OPERATE

Description

INFOID:0000000010723750

VDC function, TCS function, ABS function, EBD function, brake limited slip differential (BLSD) function, brake
assist function, brake force distribution function, hill start assist function, or advanced hill descent control func-
tion (4WD models with gasoline engine) does not operate.

Diagnosis Procedure

INFOID:0000000010723751

CAUTION:

VDC function, ABS function and EBD function never operate when the vehicle speed is 10 km/h (6.2
MPH) or less.

1.

CHECK WARNING LAMP

• Check that ABS warning lamp and VDC warning lamp turn ON and turn OFF approx. 1 second after ignition

switch is turned ON or driving.

• Check that brake warning lamp turn ON and turn OFF after engine start or driving.

CAUTION:

Brake warning lamp turns ON when parking brake is operated (parking brake switch is ON) (without
electric parking brake system) or brake fluid is less than the specified level (brake fluid level switch is
ON).
Is the inspection result normal?

YES

>> Normal

NO

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

BRAKE PEDAL VIBRATION OR OPERATION SOUND OCCURS

BRAKE PEDAL VIBRATION OR OPERATION SOUND OCCURS

Description

INFOID:0000000010723752

• 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 more]

Diagnosis Procedure

INFOID:0000000010723753

1.

SYMPTOM CHECK 1

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

YES

>> GO TO 2.

NO

>>

Check the brake pedal.

• LHD models: Refer to 

BR-22, "Inspection and Adjustment"

.

• RHD models: Refer to 

BR-86, "Inspection and Adjustment"

.

2.

SYMPTOM CHECK 2

Check that motor sound from ABS actuator and electric unit (control unit) occurs when the engine starts.

Does the operation sound occur?

YES

>> GO TO 3.

NO

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

3.

SYMPTOM CHECK 3

Check 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).

NO

>> Normal

VEHICLE JERKS DURING

Description

INFOID:0000000010723754

The vehicle jerks when VDC function, TCS function, ABS function, EBD function, brake limited slip differential
(BLSD) function, brake assist function, brake force distribution function, hill start assist function or advanced
hill descent control function (4WD models with gasoline engine) operates.

Diagnosis Procedure

INFOID:0000000010723755

1.

CHECK SYMPTOM

Check that the vehicle jerks when VDC function, TCS function, ABS function, EBD function, brake limited slip
differential (BLSD) function, brake assist function, brake force distribution function, hill start assist function or
advanced hill descent control function operates.
Is the inspection result normal?

YES

>> Normal

NO

>> GO TO 2.

2.

PERFORM SELF-DIAGNOSIS (1)

With CONSULT

Perform self-diagnosis for “ABS”.

Is DTC detected?

YES

>> Check the DTC.

NO

>> GO TO 3.

3.

CHECK CONNECTOR

With CONSULT

1.

Turn the ignition switch OFF.

2.

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

3.

Check the connector terminal for deformation, disconnection and looseness.

4.

Connect the ABS actuator and electric unit (control unit) harness connector, and perform self-diagnosis
for “ABS” again.

Is the inspection result normal?

YES

>> GO TO 4.

NO

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

4.

PERFORM SELF-DIAGNOSIS (2)

With CONSULT
