Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace error-detected parts.

2.

CHECK VDC OFF INDICATOR LAMP SIGNAL (1)

1.

Select “ABS”, “DATA MONITOR” and “OFF LAMP” according to this order with CONSULT.

2.

Turn the ignition switch OFF.

3.

Check that data monitor displays “On” for approx. 1 second after ignition switch is turned ON, and then
changes to “Off”.

CAUTION:

Never start engine.

Is the inspection result normal?

YES

>> GO TO 3.

NO

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

BRC-125, "Exploded View"

.

3.

CHECK VDC OFF INDICATOR LAMP SIGNAL (2)

1.

Select “ABS”, “DATA MONITOR” and “OFF LAMP” according to this order with CONSULT.

2.

Check that data monitor displays “On” or “Off” each time when VDC OFF switch is operated.

Is the inspection result normal?

YES

>> Check the combination meter. Refer to 

MWI-34, "Diagnosis Description"

.

• For malfunction of ABS, only the EBD is activated and the condition of vehicle is the same condition of vehi-

cles without TCS/ABS system.
NOTE:
ABS self-diagnosis sound may be heard. That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.

• For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as the

condition of vehicles without TCS/ABS, EBD system.

VDC/TCS 

If VDC/TCS/ABS system malfunction electrically, VDC warning lamp are turned on, and the condition of vehi-
cle is the same as the condition of vehicles without VDC/TCS control.

CAUTION:

If the Fail-Safe function is activated, then perform self-diagnosis for “ABS” with CONSULT.

1.

CHECK START

Check the front and rear brake force distribution using a brake tester. Refer to 

BR-52, "General Specifica-

tions"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Check the brake system.

2.

CHECK FRONT AND REAR AXLE

Make sure that there is no excessive play in the front and rear axles.
• Front
- 2WD: Refer to 

FAX-8, "Inspection"

PEDAL VIBRATION OR ABS OPERATION SOUND OCCURS

Diagnosis Procedure

INFOID:0000000007544781

CAUTION:

Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). 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]

1.

SYMPTOM CHECK 1

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

Do vibrations occur?

YES

>> GO TO 2.

NO

>> Inspect the brake pedal. Refer to 

BR-20, "Inspection and Adjustment"

.

2.

SYMPTOM CHECK 2

Check that there are ABS operation noises when the engine is started.

Do the operation noises 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.
Do symptoms occur?

YES

>> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,

move it farther away.

NO

>> Normal
