• Brake fluid is supplied to the front RH brake caliper from the master cylinder through the cut valve 2 and the

ABS IN valve. Since the suction valve 2 and the ABS OUT valve is closed, the fluid does not flow into the

reservoir. The amount of brake fluid supplied to the front RH brake caliper from the master cylinder is con-

trolled according to time that the ABS IN valve is not energized (time that the ABS IN valve is open).

SYSTEM

During front RH brake caliper release

• Brake fluid is supplied to the front RH brake caliper through the return check valve of the ABS IN valve and

the cut valve 2, and returns to the master cylinder.

During front LH brake caliper release

• Brake fluid is supplied to the front LH brake caliper through the return check valve of the ABS IN valve and

the cut valve 1, and returns to the master cylinder.

During rear RH brake caliper release

• Brake fluid is supplied to the rear RH brake caliper through the return check valve of the ABS IN valve and

the cut valve 1, and returns to the master cylinder.

During rear LH brake caliper release

• Brake fluid is supplied to the rear LH brake caliper through the return check valve of the ABS IN valve and

the cut valve 2, and returns to the master cylinder.

Component Parts and Function

CONDITION FOR TURN ON THE WARNING LAMP

Turns ON when ignition switch turns ON and turns OFF when the system is normal, for bulb check purposes.

CONDITION FOR TURN ON THE INDICATOR LAMP

Component

Function

Pump

Returns the brake fluid reserved in reservoir to master cylinder by reducing pressure.

Motor

Activates the pump according to signals from ABS actuator and electric unit (control unit).

Cut valve 1
Cut valve 2

Shuts off the ordinary brake line from master cylinder.

Suction valve 1
Suction valve 2

Supplies the brake fluid from master cylinder to the pump.

ABS IN valve

Switches the fluid pressure line to increase or hold according to signals from control unit.

ABS OUT valve

Switches the fluid pressure line to increase, hold or decrease according to signals from control unit.

Inlet valve

Brake fluid sucked from the reservoir by the pump does not backflow.

Outlet valve

Brake fluid discharged from the pump does not backflow.

Return check valve

Returns the brake fluid from brake caliper and wheel cylinder to master cylinder by bypassing orifice 
of each valve when brake is released.

Reservoir

Temporarily reserves the brake fluid drained from brake caliper, so that pressure efficiently decreas-
es when decreasing pressure of brake caliper and wheel cylinder.

INFOID:0000000012199663

VDC FUNCTION, TCS FUNCTION AND BRAKE LIMITED SLIP DIFFERENTIAL (BLSD) FUNCTION

VDC warning lamp in combination meter turn ON when a malfunction occurs in system [ABS actuator and

electric unit (control unit)]. The control is suspended for VDC function, TCS function and brake limited slip dif-

ferential (BLSD) function. The vehicle status becomes the same as models without VDC function, TCS func-

tion and brake limited slip differential (BLSD) function. However, ABS function and EBD function are operated

normally.

ABS FUNCTION

ABS warning lamp and VDC warning lamp in combination meter turn ON when a malfunction occurs in system

[ABS actuator and electric unit (control unit)]. The control is suspended for VDC function, TCS function, ABS

function and brake limited slip differential (BLSD) function. The vehicle status becomes the same as models

without VDC function, TCS function, ABS function and brake limited slip differential (BLSD) function. However,

EBD function is operated normally.

NOTE:

ABS self-diagnosis sound may be heard the same as in the normal condition, because self-diagnosis is per-

formed when ignition switch turns ON and when vehicle initially starts.

EBD FUNCTION

ABS warning lamp, brake warning lamp and VDC warning lamp in combination meter turn ON when a mal-

function occurs in system [ABS actuator and electric unit (control unit)]. The control is suspended for VDC

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

vehicle status becomes the same as models without VDC function, TCS function, ABS function, EBD function

and brake limited slip differential (BLSD) function.
