What To Do if the ABS Light Illuminates on Your Dashboard 

The warning lights on your dashboard notify you when something is wrong. Sometimes the light is a precursor for something less serious. For example, when the oil level light turns on. Other times, the warning light is informing you that a serious problem has occurred with one of the accessories on your vehicle, like the anti-lock brake system, or ABS.

Keep on reading to learn about why the ABS light on your dashboard might be illuminated, and what to do if you see this important warning sign in your vehicle.

What is an ABS light?

There are a series of lights, or symbols, on the dashboard of your car. Each one corresponds to a different sensor or accessory on your vehicle.

For the anti-lock brake system, the warning light is simply the “ABS” acronym. If and when an issue arises with the ABS on your car, this light will automatically get turned on to notify you.

What is the Anti-Lock Brake System?

In case you weren’t aware, the ABS on your car is an advanced braking feature that helps your vehicle maintain traction during heaving braking incidents.

In the past, cars would skid out of control when the driver would slam on the brakes, eliminating their ability to steer the vehicle. Nowadays, with ABS, drivers can maintain traction and steer to safety even after slamming on their brakes.

This is possible with ABS because, during a moment of heavy braking, the mechanism rapidly releases or pulsates the brake pressure, sometimes up to 30 times per second. This keeps the wheels from locking up and helps you to remain steering.

Why Is the ABS Light on in my Car?

Unfortunately, the ABS warning light does not tell you exactly what the problem is when it arises. If the ABS light is turned on, it could be related to a variety of issues within the anti-lock brake system.

  • Diminished fluid levels: the whole ABS needs adequate fluids and lubrication, without it, parts of the ABS will not operate and the warning light will illuminate.
  • Faulty hydraulic pump, or valve: the ABS relies on hydraulic fluid and if that fluid cannot travel through the because of a faulty pump, the ABS will not function properly.
  • Defective ABS module: the brain of the ABS is a miniature computer module that is sometimes prone to damage and corrosion, although it’s rare.
  • Malfunctioning wheel speed sensor: speed sensors detect the different speeds the wheels are spinning, and tell the ABS how to distribute brake fluid pressure.

How Much Will It Cost to Repair the Problem?

The cost of the repair will depend on the problem. When the ABS light is illuminated on your dashboard, it’s very important that you schedule your car for maintenance as soon as possible.

The cost of the maintenance will also depend on the:

  • Year, make, and model of your vehicle.
  • The severity of the problem.
  • Your geographic location.
  • Local market prices for automotive repairs.

Only a trained mechanic will be able to assess why the warning light is turned on. They will utilize a scan tool to perform a diagnostic check on the ABS computer, to diagnose the problem.

Refilling the fluids in your ABS is a relatively simple and cheap fix. On the other hand, replacing the entire module, or speed sensors will cost more money. Whatever the issue, the cost is worth it, because the ABS helps keep you safer while you drive.
