Starting and operating/Electronic Brake Force Distribution (EBD) system
& ABS self-check
S07AL01
Just after the vehicle is started, you may
feel on the brake pedal a vibration similar
to when the ABS operates, and you may
also hear the sound of the ABS working
from the engine compartment. This is
caused by an automatic functional test of
the ABS being carried out and does not
indicate a malfunction.

malfunctions

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 and uses some of the ABS compo-
nents to perform its function of optimizing
the distribution of braking force. If any of
the ABS components used by the EBD
system malfunction, 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.
If a malfunction occurs in the EBD system,
the system stops working and the following
warning lights illuminate simultaneously.
. Brake system warning light
. ABS warning light
. Vehicle Dynamics Control warning light
The EBD system may be malfunctioning if
all the warning lights illuminate simulta-
neously during driving.
Even if the EBD system malfunctions, the
conventional braking system will still func-
tion. However, the rear wheels will be more
prone to locking when the brakes are
applied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.
