System Description

INFOID:0000000005258639

• Anti-Lock Braking System is a function that detects wheel revolution while braking, electronically controls

braking force, and prevents wheel locking during sudden braking. It improves handling stability and maneu-

verability for avoiding obstacles.

• Electrical system diagnosis by CONSULT-III is available.

System Description

INFOID:0000000005258641

• Electric Brake force Distribution is a following function. ABS actuator and electric unit (control unit) detects

subtle slippages between the front and rear wheels during braking. Then it electronically controls the rear

braking force (brake fluid pressure) to reduce rear wheel slippage. Accordingly, it improves vehicle stability.

• Electrical system diagnosis by CONSULT-III is available.

CONSULT-III Function (ABS)

INFOID:0000000005258642

FUNCTION

CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.

SELF DIAGNOSTIC RESULT MODE

Operation Procedure

1. Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for

approximately 1 minute.

How to Erase Self-diagnosis Results

1. After erasing DTC memory, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately

1 minute as the final inspection, and make sure that the ABS warning lamp, VDC OFF indicator lamp,

SLIP indicator lamp and brake warning lamp turn OFF.

CAUTION:

If memory cannot be erased, perform applicable diagnosis.

NOTE:

• When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp,

VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the

system is normal unless the vehicle is driving at approximately 30 km/h (19 MPH) or more for approxi-

mately 1 minute.

• Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake fluid

level switch operation (when brake fluid is insufficient).

• VDC OFF switch should not stay “ON” position.

ACTIVE TEST MODE

CAUTION:

• Do not perform active test while driving vehicle.

• Make sure to completely bleed air from brake system.

• The active test cannot be performed with the ABS warning lamp, VDC OFF indicator lamp, SLIP indi-

cator lamp or brake warning lamp on.

• ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp are on

during active test.

NOTE:

• When active test is performed while depressing the pedal, the pedal depression amount will change. This is

normal. (Only solenoid valve and ABS motor.)

• “TEST IS STOPPED” is displayed 10 seconds after operation start.

• After “TEST IS STOPPED” is displayed, to perform test again, touch BACK.

Test Item

SOLENOID VALVE

• When performing an active test of the ABS function, select the “MAIN SIGNALS” for each test item. In addi-

tion, when performing an active test of the VDC/TCS function, select the item menu for each test item.

• For ABS solenoid valve, touch “Up”, “Keep”, and “Down” on the display screen. For ABS solenoid valve

(ACT), touch “Up”, “ACT UP”, “ACT KEEP” and confirm that solenoid valves operate as shown in the table

below.

Description

INFOID:0000000005258644

When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current

signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).

YES

>> Proceed to diagnosis procedure. Refer to 

BRC-27, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000005258646

Regarding Wiring Diagram information, refer to 

BRC-94, "Wiring Diagram - BRAKE CONTROL SYSTEM -

WITH VQ40DE"

 or 

BRC-102, "Wiring Diagram - BRAKE CONTROL SYSTEM - WITH VK56DE"

.

CAUTION:

Do not check between wheel sensor terminals.

1.

CONNECTOR INSPECTION

1. Disconnect the ABS actuator and electric unit (control unit) connector and wheel sensor connector of mal-

functioning code. 

2. Check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?

YES

>> GO TO 2

NO

>> Repair or replace as necessary.

2.

CHECK WHEEL SENSOR OUTPUT SIGNAL

1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.
