8DÐ284 WIRING SYSTEM
Anti-lock Brake System (ABS)
General Description
The circuit consists of EHCU (Electronic Hydraulic
Control Unit), wheel speed sensor, GÐsensor,
stoplight switch or brake switch (w/cruise control),
backup light switch, transmission switchÐ1, 2,
indicator light and data link connector.
EHCU controls brake fluid pressure applied to front
and rear wheels to prevent wheels from locking by
using speed sensor and GÐsensor signals.
Based on wheel speed signals from speed sensor,
EHCU activates solenoid valves incorporated into
the control unit to increase, maintain or decrease
brake fluid pressure.
Refer to AntiÐlock Brake System in Brakes section.
