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).

Signal description

Combination meter

Receives the following signals from ABS actuator and electric unit (control unit) via CAN com-
munication.

[ABS]

SYSTEM

• 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 ABS function and EBD func-

tion. Refer to 

BRC-24, "Fail-safe"

.

INPUT SIGNAL AND OUTPUT SIGNAL

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

ABS : Fail-safe

INFOID:0000000009365064

ABS FUNCTION

ABS 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 ABS functions. However, EBD functions operate nor-

mally.

EBD FUNCTION

ABS warning lamp and brake warning 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 ABS and EBD functions.
