How To Reset ABS (Anti-lock Braking System) Light

Are you tired of looking at that pesky ABS light on your car’s dashboard? We show you how to reset the ABS light with or without a scan tool.

ABS stands for the anti-lock brake system, and it's needed to improve traction on slippery roads. However, there are times when the ABS light can come on, indicating there is a problem with the system. When this happens, you need to know how to reset the ABS light and enjoy a safe drive.  

The ABS is part of all modern vehicles, ensuring that the speed sensors, wheels, and braking system work together in harmony to improve traction and safety. The purpose of the system is to prevent accidents from happening.  

The ABS prevents wheels from locking up, giving you control over your vehicle in less than ideal conditions. At first, the system was used on aircraft during the 1950s. Just a couple of decades later, both Chrysler and Ford became pioneers by offering it on automobiles.

Common Reasons Your ABS Light Is On 

Bad Wheel Speed Sensor 

The speed sensor checks how fast the wheel is traveling. It also ensures that the ABS turns on when one wheel is moving faster than the rest. If the sensor is faulty, the ABS light will come on to indicate there is trouble with the system.  

Worn Hydraulic Pump Or Valve 

The ABS sensor monitors the hydraulic pump and valves as well. The pump is needed to increase pressure on the brakes when the wheel speeds are going faster than others. Hydraulic pressure needs to be used to apply the brakes appropriately, but a faulty system can trigger the ABS light.  

Bad ABS Tone Ring 

The ABS ring is used to measure speed from the wheel sensors. When it fails, the ABS light can come on. Additionally, you might notice that the brake pedal pulsates, or the vehicle loses some of its braking ability.  

Low Levels in the Fluid Reservoir 

Brake fluid is needed to activate the system. When there isn’t enough fluid in the system, the ABS light can come on to indicate it’s time to refill the reservoir. Letting the fluid run low can also lead to air infiltrating the system.  

Faulty Or Broken Wires To ABS Sensor 

The ABS system contains numerous wires that can become faulty over time. If one of the wires malfunctions or breaks, the ABS sensor won’t receive an appropriate signal, leading to the light coming on.  

Bad Brake Pedal Sensor / Light Switch 

Whenever there is a problem with the brake pedal, the ABS light can come on to alert you. Whether the brake pedal itself is causing a problem or the light switch has malfunctioned, the alert tells you to fix the fault.  

Corroded ABS Module 

All metal parts can become rusted over time, including the ABS module. When this happens, the system can malfunction due to a lack of communication. In this case, the ABS module will need to be replaced.

  1. 1
    Gather your equipment before getting started. You will need a fused jumper wire if you don’t have a scan tool. Aside from this, there’s no other equipment that should be required other than what was needed to repair the broken component that set off the trouble code in the first place.  
  2. 2
    Find the data link connector in your vehicle. The DLC is typically located under the driver’s side dash or below the glove box. Sometimes, it is also in the engine compartment, located near the intake manifold. 
  3. 3
    With the ignition off, connect the two DLC fuses with a jumper wire.  
  4. 4
    Turn on the ignition but don’t crank the engine. Wait until you see the ABS light come on and flash a few times.  
  5. 5
    Push the brake pedal down. You should hear a click sound, which indicates when you should release the brake. Continue pushing and releasing the brake pedal eight times over three seconds. The ABS light should stop flashing at this point. It will illuminate for a second and flash four times to show that the code has been cleared.  
  6. 6
    Turn the vehicle off and remove the connectors you hooked up.  

While you might be able to figure out how to reset an ABS warning light without repairing the problem first, this process will be fruitless. Without repairing the fault, the ABS light is going to come on again as soon as the trouble code sets. That’s why you want to have the problem repaired before you follow our steps above.
