ABS CONTROL FUNCTION

• ABS control is basically the same as that for vehicles with ABS. However, fluid pressure in each wheel is under
independent control in this system.

• EBD control has an independent control system for the front and rear wheels, as well as vehicles with ABS,
which constantly and properly distributes brake fluid regardless of vehicle weight (number of passengers).
