GENERAL DESCRIPTION

M1352000100528

The ABS consists of components such as the wheel
speed sensors, stoplight switch, hydraulic unit
assembly (integrated with ABS-ECU) and the ABS
warning light. If a problem occurs in the system, the
malfunctioning components can be identified and the
trouble symptoms will be memorized by the diagnos-
tic function.
The system has the EBD (Electronic Brake-force
Distribution) control system which provides the ideal
braking force for the rear wheels.
In addition, reading of diagnostic trouble codes and
data list and actuator testing are possible by using
the Scan Tool.

.

EBD CONTROL
In ABS, electronic control method is used whereby
the rear wheel brake hydraulic pressure during brak-
ing is regulated by rear wheel control solenoid valves
in accordance with the vehicle's rate of deceleration
and the front and rear wheel slippage which are cal-

culated from the signals received from the various
wheel sensors. EBD control is a control system
which provides a high level of control for both vehicle
braking force and vehicle stability. The system has
the following features:

• Because the system provides the optimum rear

wheel braking force regardless of the vehicle
laden condition and the condition of the road sur-
face, the system reduces the required pedal
depression force, particularly when the vehicle is
heavily laden or driving on road surfaces with
high frictional coefficients.

• Because the duty placed on the front brakes has

been reduced, the increases in pad temperature
can be controlled during front brakes applying to
improve the wear resistance characteristics of the
pad.

• Control valves such as the proportioning valve

are no longer required.
