ABS CONTROL OPERATION

• When the ABS CM determines wheel slip conditions based on the signals from the ABS wheel-speed sensors
during braking, the ABS CM operates the ABS HU inlet and outlet solenoid valves, reducing and maintaining
brake fluid pressure in accordance with the wheel slip factors. Then, when the wheel slip condition has passed,
brake fluid pressure is increased and maintained, ensuring braking with a constantly stable brake force.

EBD CONTROL OUTLINE

• EBD control uses the ABS system to control brake fluid pressure distribution to the rear wheels so that they do
not lock-up prior to the front wheels during braking, thereby preventing the loss of handling stability.
Features
• EBD control has independent control systems for both the front and rear wheels.
• EBD control constantly and properly distributes brake fluid pressure regardless of vehicle weight.
