ABS Anti Lock Break System

What is an ABS?

ABS or an Anti-lock braking system is used in vehicles to help you steer back to safety in emergencies by restoring traction to your tires. It prevents the wheels of the vehicle from locking up during braking by working with the car’s regular braking system and automatically pumping them in any unforeseen event of a sudden stop.An ABS assembly generally consists of an ECU (Electronic Control Unit), four wheel speed sensors and at least two hydraulic valves within the brake hydraulics. The ECU monitors the rotational speed of each wheel constantly and if it detects the wheel rotating significantly slower than the speed of the vehicle indicating an impending wheel lock, it activates the valve to reduce hydraulic pressure to the brake of the affected wheel, thus reducing the braking force on that wheel which will in turn help the wheel turn faster. Similarly, if the ECU detects any wheel turn significantly faster than the others, brake hydraulic pressure to that particular wheel is increased so that the braking force is reapplied and the wheel is slowed down.

How to identify a faulty ABS?

The ABS control module or ABS controller is a microprocessor that runs diagnostic checks of the vehicle’s ABS. It processes the information it receives from wheel-speed sensors and hydraulic brake system and determines when to release braking pressure at a wheel that’s about to lock up and start skidding.

Here are a few common symptoms of a faulty ABS –

1.The ABS Light Is ON – A dashboard ABS warning light usually comes on for a few seconds every time the vehicle is started, but if it comes on while you are driving, then it signals that one of the following has occurred – conked out control module, low brake fluid, a faulty ABS sensor, an ABS module failure, a worn ABS pump or a bulb check error.

2. Locking Wheels – If you feel like your wheels are locking up while slamming the brakes, the ABS control module might be to blame and it might be time to take the vehicle to a mechanic.

3. Increased Braking Effort – If you feel that the necessary force that needs to be exerted to push down the brake pedal keeps increasing as time goes on, it might be time to get your vehicle’s ABS checked out.

4. Unresponsive Brake Pedal – You will start by a decrease in brake performance as mentioned above and eventually to the brakes being completely unresponsive. This is a very strong indicator of a deteriorating ABS control module.

5. Inaccurate Speedometer Readings – When the ABS module fails, sometimes the speedometer will show incorrect readings. However, this isn’t a common occurrence and only a possibility.
