Electronic Brake Force Distribution (EBD) system

7-10. Electronic Brake Force
Distribution (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 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.
& Steps to take if EBD system
malfunctions
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.
If all the warning lights illuminate simulta-
neously, take the following steps.
1. Stop the vehicle in the nearest safe, flat
location.
2. Apply the parking brake and turn off the
hybrid system.
3. Restart the hybrid system.
4. Release the parking brake.
If all the warning lights do not come
back on:
The EBD system have a possible malfunc-
tion. Drive carefully to the nearest
SUBARU dealer and have the system
inspected.
If all the warning lights stay illuminated
or come back on after approximately 2
seconds:
1. Turn off the hybrid system again.
2. Apply the parking brake.
3. Check the brake fluid level. For details
about checking the brake fluid level, refer
to "Checking the fluid level" FP434.
. If the brake fluid level is not below the
"MIN" mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
. If the brake fluid level is below the "MIN"
mark, DO NOT drive the vehicle. Instead,
