Title:

Reasons for an Illuminated ABS Light

Description:

The ABS light in the dashboard gets illuminated when there is an issue in the anti-braking system of the car. There are various factors like low fluid level, bad hydraulic pump or a bad ABS module which keeps the light on. In order to know the details about the reasons for an illuminated ABS light, see the below s. – PowerPoint PPT presentation

Title: Reasons for an Illuminated ABS Light


1
Reasons for an Illuminated ABS Light
2
The ABS exists to avoid your car from skidding
dangerously during braking.
3
It is an automated safety system that recognizes
when your wheels stop rotating while on the road
and it releases brake fluid pressure allowing the
wheels to continue to rotate.
4
This improves the car's handling and stops the
car from locking up and skidding out of the road.
5
The moment any issue outbreaks in the ABS, a
corresponding light named ABS glows up on your
dashboard.
6
Here are some of the common reasons for an
illuminated ABS light
7
Faulty speed sensor
8
These sensors are built into every wheel's hub,
which determines the rate at which the wheels are
moving transmits the data to the anti-lock
braking system(ABS).
9
When the ABS gets to know that one or more wheels
are moving slower than others, then it releases
the brake fluid pressure for uniform wheel
movement.
10
But if the speed sensor is a faulty one, then
the ABS will detect that and the warning light
gets flashed on the dashboard.
11
Low fluid level
12
The brake fluid plays a vital role in controlling
the braking pressure within the ABS.
13
When the ABS fluid reservoir is low, then the
content of air is more and the ABS will not work
properly.
14
This also results in the glowing of the ABS light
on the dashboard.
15
Bad hydraulic pump
16
When any wheel is moving slower than others, then
the hydraulic valve is responsible for increasing
the brake fluid pressure.
17
As a result, the wheel does not lose traction
with the ground and the car remains stable.
18
This hydraulic pump may also be damaged due to
internal wear because of the dirty brake fluid
and its malfunction is conveyed by the ABS light.
19
Bad ABS module
20
A faulty ABS module disturbs the transfer of
information from the speed sensors in the wheels
to the ABS.
21
The problem in the relay of the information is
mainly due to corrosion in the module or some
issues in the wiring.
22
In such cases, also the ABS light is on and
indicates to replace the ABS functional module.
23
Issues in the bulb
24
The reason for the illuminated ABS light might
have nothing to do with the ABS functional module
as the problem may be with the light.
25
Regular checks should be done to be sure that all
the bulbs of the car's warning lights on the
dashboard are working properly.
26
If the bulb of the ABS warning light is not
functioning properly, then it might remain on all
by itself.
