1995 NISSAN ALMERA N15 warning light

ANTI-LOCKBRAKESYSTEM
Purpose

The Anti-Lock BrakeSystem (ABS)consists ofelectronic andhydraulic components. Itallows forcon-
trol ofbraking forcesothat locking ofthe wheels canbeavoided.
The ABS:
1) Improves propertracking performance throughsteering wheeloperation.
2) Eases obstacles tobe avoided throughsteering wheeloperation.
3) Improves vehiclestability bypreventing flatspins.

Operation

• When thevehicle speedisless than 10km/h (6MPH) thissystem doesnotwork.
• The Anti-Lock BrakeSystem (ABS)hasself-test capabilities. Thesystem turnsonthe ABS warning
light for1second afterturning theignition switchON.The system performs anothertestthefirst time
the vehicle reaches 6km/h (4MPH). Amechanical noisemaybeheard asthe ABS performs aself-
test. This isanormal partofthe self-test feature.Ifa malfunction isfound during thischeck, theABS
warning lightwillcome on.
• During ABSoperation, amechanical noisemaybeheard. Thisisanormal condition.

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. :•

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.
