REMOVAL AND INSTALLATION

Caution
Do not drop the G sensor or subject it to any shocks.

Pre-removal and Post-installation Operation
Rear floor console removal and installation

G sensor

INSPECTION

1.

Remove the G sensor.

2.

Connect the special tool between the disconnected
connectors, and then place the G sensor horizontally as
shown in the illustration.

3.

Turn on the ignition switch, and then measure the voltage
between terminal No.2 and body earth.

Standard value: 2.4 – 2.6 V

4.

Face the labeled surface straight down with the special
tool still connected. Measure the voltage between terminal
No.2 and body earth with the labeled surface faced straight
down.

Standard value: 3.3 – 3.7 V

5.

If not within the standard value, check the power supply
line and earth condition, and then replace the G sensor.

GENERAL

OUTLINE OF CHANGES



The hydraulic unit (integrated with the ABS-ECU) has been reshaped. In addition, the troubleshooting
has been changed due to the change on the ABS-ECU connector.



The Electronic Brake-force Distribution (EBD) has been adopted. The EBD makes it possible to maintain
the maximum amount of braking force for the rear wheels even when the vehicle’s load is unevenly
distributed

GENERAL INFORMATION

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
calculated 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
surface, 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 temper-
ature can be controlled during front brakes ap-
plying to improve the wear resistance character-
istics of the pad.



Control valves such as the proportioning valve
are no longer required.
