Opel Frontera UBS. Manual - part 1652

8D–286

WIRING SYSTEM

Anti-lock Brake System (ABS)

General Description

The circuit consists of EHCU (Electronic Hydraulic
Control Unit), wheel speed sensor, G–sensor,
stoplight switch or brake switch (w/cruise control),
backup light switch, transmission switch–1, 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 G–sensor 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 Anti–lock Brake System in Brakes section.
