• During braking, control unit portion compares slight slip on front

and rear wheels by wheel speed sensor signal, transmits drive sig-

nal to actuator portion when rear wheel slip exceeds front wheel

slip for the specified value or more, and controls rear wheel brake

force (brake fluid pressure) so that increase of rear wheel slip is

prevented and slips on front wheel and rear wheel are nearly

equalized. ABS control is applied when slip on each wheel

increases and wheel speed is the threshold value of ABS control or

less.

• CONSULT can be used to diagnose the system.

• Fail-safe function is adopted. When a malfunction occurs in EBD

function, the control is suspended for VDC function, TCS function,

ABS function and EBD function. Refer to 

BRC-29, "VDC/TCS/ABS

: Fail-safe"

.

INPUT SIGNAL AND OUTPUT SIGNAL

Major signal transmission between each unit via communication lines is shown in the following table.

INFOID:0000000009267599

VDC AND TCS FUNCTIONS

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

electric unit (control unit)]. The control is suspended for VDC and TCS functions. However, ABS and EBD

functions operate normally.

ABS FUNCTION

ABS warning lamp and SLIP indicator lamp in combination meter turn ON when a malfunction occurs in sys-

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

However, EBD functions operate normally.

EBD FUNCTION

ABS warning lamp, brake warning lamp and SLIP indicator 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,

TCS, ABS and EBD functions.

APPLICATION ITEMS

CONSULT can display each diagnostic item using 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-diagnosis, start 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 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,

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.
