Starting and operating/Electronic Brake Force Distribution (EBD) system
Electronic Brake Force Distribution (EBD) system
The EBD system maximizes the effectiveness 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 components 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.
& Steps to take if EBD system
malfunctions
Brake and ABS warning light (type A)
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.
system warning light and ABS warning
light illuminate simultaneously.
The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
during driving.
Even if the EBD system malfunctions, the
conventional 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
vehicle’s motion may therefore become
somewhat harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps.
1. Stop the vehicle in the nearest safe,
flat location.
2. Apply the parking brake and turn off
the engine.
3. Restart the engine.
4. Release the parking brake.
Even if both warning lights turn off:
The EBD system may be malfunctioning.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
Brake and ABS warning light (type B)
If a malfunction occurs in the EBD system,
the system stops working and the brake
If both warning lights illuminate again
and remain illuminated after restarting
the engine:
1. Turn off the engine again.
