THE BRAKING DISTANCE IS LONG

Description

INFOID:0000000010329880

Brake stopping distance is long when ABS function is operated.

Diagnosis Procedure

INFOID:0000000010329881

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

Is the inspection result normal?

DOES NOT OPERATE

DOES NOT OPERATE

Description

INFOID:0000000010329882

VDC function, TCS function, ABS function, EBD function, Brake limited slip differential (BLSD) function, Brake
assist function, hill start assist function or Brake force distribution function does not operate.

Diagnosis Procedure

INFOID:0000000010329883

CAUTION:

• VDC function, TCS function, ABS function, EBD function, Brake limited slip differential (BLSD) func-

tion, Brake assist function, hill start assist function and Brake force distribution function never oper-
ate when the vehicle speed is 10 km/h (6.2 MPH) or less. However, TCS function, Brake limited slip
differential (BLSD) function and hill start assist function operates when the vehicle speed is 0 km/h
(0 MPH) (the vehicle is in stop status).

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

indicator lamp turns ON).

1.

CHECK ABS 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

NO

>> GO TO 2.

2.

PERFORM SELF-DIAGNOSIS

With CONSULT

1.

Turn the ignition switch OFF 

 ON.

CAUTION:

• Be sure to wait of 10 seconds after turning ignition switch OFF or ON.
• Start the engine.

2.

Repeat step 1 two or more times.

3.

Perform self-diagnosis for “ABS” with CONSULT.

Is any DTC detected?

YES

>> Check the DTC. Refer to

BRAKE PEDAL VIBRATION OR OPERATION SOUND OCCURS

Description

INFOID:0000000010329884

• 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:0000000010329885

1.

SYMPTOM CHECK 1

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

YES

>> GO TO 2.

NO

>> Check brake pedal. Refer to 

BR-8, "Inspection and Adjustment"

.

2.

SYMPTOM CHECK 2

Check that motor sound from ABS actuator 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
