Description
SENSOR

The sensor unitconsists ofagear-shaped sensorrotoranda
sensor element. Theelement contains abar magnet around
which acoil iswound. Thesensor isinstalled onthe back side
of the brake rotor.Sine-wave currentisgenerated bythe sen-
sor asthe wheel rotates. Thefrequency andvoltage increase(s) •
as the rotating speedincreases. :•

V: Induced electromotive force

SBR124B
SBR049DA CONTROL
UNIT

The control unitcomputes thewheel rotating speedbythe sig-
nal current sentfrom thesensor. Thenitsupplies aDC current
to the actuator solenoid valve.Italso controls ON-OFFopera-
tion ofthe valve relayandmotor relay.Ifany electrical malfunc-
tion should bedetected inthe system, thecontrol unitcauses
the warning lamptolight up.Inthis condition, theASS willbe
deactivated bythe control unit,andthevehicle's brakesystem
reverts tonormal operation.
