Anti Lock Brake System Diagnosis and Repair

ABS light on? Anti Lock Brake System not working?

Basically, ABS prevents your wheels from locking up when you apply too much pressure to your brakes. If your wheels stop rotating, your axle will lock up too. Your car skids when you stop turning your wheels while moving too fast. Skidding results in slipping and losing total control, which is risky at high speeds.

Antilock brake systems don’t actually slow your car down faster than traditional brake systems – in fact, they add a little extra time to the stopping distance. You are still able to control your car, therefore avoiding serious injury if an accident occurs. Furthermore, it increases the life expectancy of your tires, brake pads, brake calipers, wheels, and many other parts of your car that are influenced by your braking.


Can you explain how anti-lock brakes work?

Anti-lock brakes (and skidding) are a vital safety feature during emergency stops. But how do they work? ABS monitors the speed, wheel slip, and brake force applied to your vehicle under certain conditions using electronic sensors and high-pressure pumps. Whenever your ABS senses skid hazards, it will automatically pump the brakes more quickly and accurately than you could do by yourself.

The anti-lock brake system helps you in what ways? As you brake or stop on slick surfaces, ABS helps you maintain control of your vehicle. Maintaining traction and steering instead of skidding is achieved by preventing the wheels from locking. The main purpose of anti-lock brakes is not to decrease braking distance; rather, they are used to decrease the time it takes to stop.


ABS Diagnosis: The anti-lock brake light may illuminate for four different reasons:

You need to get your ABS system checked if you see an ABS indicator light on your dashboard. In most cases, this will happen when these four things happen: broken wheel speed sensors, malfunctioning ABS modules, low fluid levels in reservoirs, and having turned off the system.

ABS module not functioning:

Several important ABS components are shared by another important system in your vehicle: your traction control system. Keeping all four wheels on the ground rolling smoothly is the primary function of traction control. It will cut off power from your engine when it detects an irregular wheel rotation until it can regain stable traction. A power-limiting device prevents you from accidentally applying too much power and skidding out of control. Due to the fact that ABS and traction control each use the same control module and self-diagnostics, one can sometimes interfere with the other. Your ABS light can come on because of a traction control issue, but it can also be caused by an issue with your ABS system. If you want to find out what’s wrong with your vehicle, you’ll need to have it professionally diagnosed.

Fluid reservoir at low levels:

Your car’s brake system relies on hydraulic power to bring your brake pads to a stop by applying force to a cylinder pushing against a fluid. It means your brake system needs to be filled with fluid consistently. It is possible, however, for the brake fluid to evaporate off if there’s a slow leak. If this happens, your brakes will not function properly. If the ABS light is triggered, sensors will detect this.

Sensors on wheels that are broken:

Sensors measure how fast each wheel spins independently and transmit the information to your computer. Your traction control system adjusts or switches power to different wheels if the computer detects an anomaly in these speeds. The speed sensor can, however, not relay accurate information if it is dirty or stops working. The system usually disables your ABS and/or traction control system rather than making a bunch of adjustments until the problem is solved or your vehicle is restarted.

You have turned off your system:

Your traction control or ABS may actually provide you with the option to turn them on and off. The indicator light on your dashboard will usually turn on when you turn off the system to warn you that this important safety feature no longer works. You may have accidentally turned off your traction control or ABS system, if just your traction control or ABS light is on. Check your owner’s manual if you don’t know where the switch is located and see if you bumped it accidentally.


What are the safety implications of driving with the ABS light on?

As long as your brakes are working normally, it’s safe to drive with the ABS light on, but it’s less safe than driving with a functioning anti-lock braking system. You’re more likely to experience brake lock and skidding if the ABS light is illuminated in situations where ABS would normally engage. We recommend getting your ABS system checked out as soon as possible.


If you have the ABS light on and the brake light on, is it safe to drive?

The ABS and brake lights on most vehicles at the same time are dangerous. You will see the brake light if your brake pads are low or if your brake fluid is low. If an ABS system problem is detected on an older vehicle, the brake light and ABS light may flash simultaneously. A good rule of thumb is to consider your brakes unreliable, and see your Midas expert right away unless your vehicle falls into one of these categories.


Is there a reason why sometimes my brake pedal pulsates?

Your ABS might pump the brakes if you notice a pulsating brake pedal during sudden stops or on slippery roads. Maintain braking until you reach your destination.
