About the ABS sensor system, Symptoms &
Diagnosing
Anti-lo
ck Braking
Systems Anti-lo
ck braking
systems (AB
S) are common on newer model
cars. AB
S controls the braking ability of
the car under select
driving conditions
that result in a loss of traction.
Th
is system features a
controller, va
lves, and speed sensor that
work in conjunction to determine the safe braking ability of your
car. AB
S speed sensors monitor the rotation
of each tire, making sure that each wheel
is rotating
properly. Any
slippage or difference between the wheels triggers the
AB
S system.
Parts of
the AB
S > AB
S
begins with sensors deciding if the wheels are losing traction.
Once th
is dec
ision
is made, the controller (like a computer)
engages a va
lve system in the vehicle that
controls available brake fluids in the lines.
Since brakes work based on pressure generated by fluid
compressed in the brake lines, a pump engages in the braking system
to rapidly apply the brakes.
Th
is application occurs faster than any human can apply
the brakes. Many
drivers feel a pulsing
feeling in the brake pedal or hear a grinding no
ise when the AB
S engages on
their vehicle. Evaluating
Speed
AB
S speed sensors are located at the wheel
hubs of the vehicle.
These sensors
constantly monitor the rotation of each wheel to evaluate whether
the AB
S system needs to override manual
braking of the vehicle in slippery conditions.
The speed sensor calculates
revolutions as well as evaluates continuity
between all wheels. Any detection of differences in rotation can
result in AB
S engaging to control braking.
Generating the
Speed
Sensor
Signal
Speed sensors are compr
ised of a
mag
net wrapped in a coil and a toothed
sensor ring mounted around the C
V joint hub.
An electrical field given off by the contact between the
mag
net and the toothed ring
creates a signal.
The
composition of the signal includes measurements of the number of
pulses per second
created by the electrical
field
existing
between the mag
net coil and sensor ring.
Th
is signal converts
to a digital signal and
is transmitted to
the AB
S controller.
Sending Messages to the AB
S
Controller
Speed sensors convert the pulses
created by the contact between the mag
net and sensor ring through a coil attached to the
sensor.
Th
is
voltage
is passed
along to the controller.
The controller
counts the number of pulses to determine wheel speed and evaluates
whether the AB
S system should intercede to
control braking. Diagnosing
Symptoms of a bad
AB
S unit
- Open the fuse panel by pulling down on the fuse panel cover
in the driver's side footwell.
- Locate the fuse for the ABS sensor
using the fuse diagram on the underside of the fuse panel cover.
-
Pull the fuse for the ABS using the fuse pullers in the fuse box.
- Check the fuse for the
ABS. If the fuse is broken or damaged in some way, then replace it
with a new fuse of the same amperage. The ABS light could come on
if there is a short in the system and
it blows the fuse.
-
Turn the ignition to the "On" position
but do not crank the engine. If the
ABS light comes on, crank the engine. If it stays on for more than five
seconds, there is a failure in the
ABS system, and it needs to be serviced
by a professional mechanic.
