Front RH brake caliper
• Brake fluid is conveyed to the pump from the master cylinder through suction valve 1 and is pressurized by
the pump operation. The pressurized brake fluid is supplied to the front RH brake caliper through the ABS IN
valve. For the left caliper, brake fluid pressure is maintained because the pressurization is unnecessary. The
pressurization for the left caliper is cont rolled separately from the right caliper.
Front LH brake caliper• Brake fluid is conveyed to the pump from the master cylinder through suction valve 2 and is pressurized by
the pump operation. The pressurized brake fluid is suppl ied to the front LH brake caliper through the ABS IN
valve. For the right caliper, brake fluid pressure is maintained because the pressurization is unnecessary.
The pressurization for the right caliper is controlled separately from the left caliper.
Rear RH wheel cylinder
• Brake fluid is conveyed to the pump from the master cylinder through suction valve 2 and is pressurized by
the pump operation. The pressurized brake fluid is supplied to the rear RH wheel cylinder through the ABS
IN valve. For the left wheel cylinder, brake fluid pressure is maintained because the pressurization is unnec-
essary. The pressurization for the left wheel cylinder is controlled separately from the right wheel cylinder.
Rear LH wheel cylinder• Brake fluid is conveyed to the pump from the master cylinder through suction valve 1 and is pressurized by
the pump operation. The pressurized brake fluid is s upplied to the rear LH wheel cylinder through the ABS
IN valve. For the right wheel cylinder, brake fluid pressure is maintained because the pressurization is
unnecessary. The pressurization for the right wheel cylinder is controlled separately from the left wheel cylin-
der.

O PCONDITIONS FOR INDICATOR LAMP ILLUMINATION
• Turns ON when VDC and TCS functions are switched to non-operational status (OFF) by VDC OFF switch.
• Turns ON when ignition switch turns ON and turns OFF when the system is normal, for bulb check purposes.
CONDITIONS FOR WARNING LAMP ILLUMINATION
Turns ON when ignition switch turns ON and turns OFF when the system is normal, for bulb check purposes.
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.
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.
Pressure sensor Detects the brake fluid pressure and tr ansmits signal to ABS ac tuator and electric unit (control unit).

APPLICATION ITEMS
CONSULT can display each diagnostic item us ing the following direct diagnostic modes.
ECU IDENTIFICATION
ABS actuator and electric unit (control unit) part number is displayed.
SELF DIAGNOSTIC RESULT
Operation Procedure
1. Before performing the “Self Diagnostic Result”, st art engine and drive vehicle at 30 km/h (19 MPH) or
more for approximately 1 minute.
How To Erase Self Diagnostic Result
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 t hat 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,
SLIP indicator lamp and brake warning lamp will not turn OFF even when the system is normal, unless
the vehicle is driven at approximately 30 km/h (19 MPH) or more for approximately 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 in ON position.
Display Item List
Refer to BRC-43, "DTC Index".
