INFOID:0000000009757821

SYSTEM DIAGRAM

• By preventing rear wheel slip increase through rear wheel brake force (brake fluid pressure) control that is

electronically controlled when slight skip on front and rear wheels are detected during braking, stability dur-

ing braking is improved.

• EBD function is expanded and developed from conventional ABS function and corrects rear wheel brake

force to appropriate level by electronic control according to load weight (number of passengers).

Component

Signal description

Combination meter

Receives the following signals from ABS actuator and electric unit (control unit) via CAN com-
munication.
• VDC warning lamp signal
• ABS warning lamp signal

[VDC/TCS/ABS]

SYSTEM

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

and rear wheels by wheel sensor signal, transmits drive signal 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 pre-

vented and slips on front wheel and rear wheel are nearly equal-

ized. 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-28, "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.

VDC/TCS/ABS : Fail-safe

INFOID:0000000009757822

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.
