Electronic Brake Force Dis-

tribution (EBD) system

The EBD system maximizes the effective-

ness of the brakes by allowing the rear

brakes to supply a greater proportion of

the braking force. It functions by adjusting

the distribution of braking force to the rear

wheels in accordance with the vehicle’s

loading condition and speed.

The EBD system is an integral part of the

ABS system and uses some of the ABS

system’s components to perform its func-

tion of optimizing the distribution of brak-

ing force. If any of the ABS components

used by the EBD function fail, the EBD

system also stops working.

When the EBD system is operating, you

may hear a chattering noise or feel a slight

vibration in the brake pedal. This is normal

and does not indicate a malfunction.

& Steps to take if EBD system

fails

If a malfunction occurs in the EBD system,

the system stops working and the brake

system warning light and ABS warning

light come on simultaneously.

The EBD system may be faulty if the

brake system warning light and ABS

warning l ight illuminate simultan eously

during driving.

Even if the EBD system fails, the conven-

tional braking system will still function.

However, the rear wheels will be more

prone to locking when the brakes are

applied harder than usual and the vehi-

cle’s motion may therefore become some-

what harder to control.
