If your ABS light remains illuminated, this indicates an issue with your car’s anti-lock
braking system (ABS), an essential safety feature that helps you drive in adverse
conditions safely. If this light illuminates, please reach out to our service department
immediately so we can address it as quickly as possible.
As the first step in diagnosing any electrical problem, always begin by checking the
fuse. If this proves successful, the issue could lie elsewhere such as with sensors.
Brakes
ABS systems prevent your wheels from locking up during hard braking. As a critical
safety feature, they play an integral role in keeping steering and directional stability
when using extreme braking force to avoid skidding or skidding altogether.
Furthermore, this feature helps drivers maintain control of their vehicles should
another car pull out in front of them suddenly or when something like deer jump out
in the middle of the road suddenly.
Faulty wheel speed sensors are often responsible for an ABS warning light being
activated. These sensors, located within each wheel hub and exposed to harsh
conditions, may become damaged over time due to wear-and-tear.
To inspect the condition of your sensor, disconnect and drain the battery by first
disconnecting its positive cable, followed by its negative cable. This should reset
your computer and possibly switch off ABS. If the problem still exists, a diagnostic
scanner could help read codes to pinpoint it further.
Tires
Your Toyota Camry’s tires are an integral component of its performance and safety.
If your tire pressure falls too low, an ABS light may illuminate and your driving
abilities could become impaired; reduced wheel diameter may trigger an ABS fault
code in the control module.
An out of balance tire indicates the need for replacement. To remedy the situation,
use your dashboard’s tire inflation gauge to regularly check and adjust pressure on
each tire accordingly.
Rear passenger seatbelt reminder lights (those shaped like sitting passengers)
illuminate to remind backseat passengers to secure their belts before driving. Failing
to fasten one could lead to loss of control or injury for all those involved.
Brake Fluid
Anti-lock braking uses sensors on each wheel that send speed data directly to an
electronic controller. If a sensor becomes inoperative and stops sending accurate
information, the ABS module (known as Hydraulic Control Unit) detects that wheels
have locked up and attempts to restore traction by pulsing brake fluid pressure
directly to each wheel – this action should also trigger your dashboard’s BRAKE light.
If the lights remain illuminated, first try disconnecting both engine and battery for
several minutes to reset your computer and clear any temporary problems with
misinterpreting data from sensors or hydraulics. If that does not help, consult your
service manual for voltage and resistance values of sensor pins and wires as this
could provide insight. Alternatively use a multimeter to physically check for damage
or corrosion to wires or sensors.
ABS Pump
If your ABS system or brake pedal becomes inactive, or activation no longer
activates properly, this could be a telltale sign that it is time for replacement of its
pump. Although this repair could be costly, doing it sooner rather than later could
save lives and reduce accidents on the road.
Your wheel speed sensors help record and transmit information on each of your
wheels’ speeds to your ABS module for use by your ECU in controlling multiple
systems on your car, including ABS. Without working sensors, ECU will not be able to
accurately determine each wheel’s speed causing its light to illuminate prematurely.
These sensors could be the source of your ABS light coming on due to corrosion on
their wires, and may need replacing or bridging between two pins with short wire
pieces or paperclips to work again. You can often address this problem by pulling a
connector and connecting two pins with some short pieces of wire or paperclip.
