WIRING SYSTEM

Anti–Lock Brake System (ABS)

General Description

The circuit consists of the Electronic Hydraulic Control
Unit (EHCU), the starter switch, stoplight switch, wheel
speed sensor, ABS warning light, BRAKE warning light,
and data link connector.
When the service brake is applied while in the running
mode, the EHCU judges which wheel is about to lock by
using the wheel rotation speed signals sent from the three
wheel speed sensors at the front wheels and rear
differential. And the brake fluid pressure applied to the
four wheels is controlled by the EHCU to prevent the
wheels from locking.
Refer to Brake Control System in Brakes section in detail.
