Anti Lock Brake System (ABS)
(if fitted)
ABS combined with the traditional
hydraulic brake system prevents the
wheel from locking while braking by
making use of most of road to tyre
grip. It also ensures better control
and stability of vehicle while braking.
How ABS works
ABS essentially consists of an
Electronic Control Unit (ECU) which
reads signals from the sensors fitted
to each wheel and identifies the one
which is likely to lock. (Wheels will
tend to lock when the speed of
rotation of any one wheel becomes
too low in relation to the vehicle
speed.) It tells an Electronic Control
Unit (ECU) to reduce, maintain or
increase the pressure on the
modulator valve in order to prevent
the wheel from locking. The ABS
comes into play when the vehicle is
braked heavily during emergency or
road surface is wet or slippery.
The driver feels modulation of
air pressure (some sound from
modulator valve)
This is absolutely Normal. This
should not be interpreted as a
fault in the brakes. On the
contrary it’s the indication that
the ABS is working. This is an
intentional warning to the driver that
a wheel or wheels are tending to
lock due to the limit of tyre to road
adhesion. The ABS is addition to the
basic brake system. It is activated
automatically every time the engine
is started. If there is a malfunction
the system turns off automatically
indicated by a ‘(ABS)’ warning
indicator on the dash board, still the
ordinary brake system continues to
work.
ABS Activation
ABS activation varies with various
road surfaces i.e. the amount of
traction your tyre have on a
particular surface. On dry surface you
will need more pedal effort to
activate ABS. However you may feel
ABS activates immediately if you try
to stop on snow, ice or slippery
surface.
ABS Indicators
4.10 Brake system Maintenance
The ABS is self check. If
any thing goes wrong
the ABS warning indicator comes on
the instrument panel. When you
switch on the Ignition the ABS light
turns ON but should go out after
about 5 seconds. If the light fails to
go or the lighting up of the warning
light when the engine is running or
the light comes at any other time, it
indicates there is a fault in the ABS
only. In this case also the normal
braking system is still effective and
is able to provide normal stopping
ability.
In this condition it is recommended
to take your vehicle to the nearest
authorized Dealer / service outlet
and get your vehicle attended as
soon as possible if the warning light
stays on.
