Electronic Brake Force Distribution ( EBD ) system
S07AM
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 .
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
S07AM01
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 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 all the warning lights 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 .
If all the warning lights do not come back on :
The EBD system have a possible malfunction . 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 engine 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 ” F11-15 .
. 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 .
