What happens when you press on the brakes?
When you press on the brakes, the brake calipers force the brake pads to clamp down on the brake rotors. If this clamping force exceeds the available traction between the ground and the tire, that tire will actually stop spinning. This is known as locked brakes. Under heavy braking, one or more tires may lock and could initiate a slide.
1. Turn the key on
Place the key into the keyhole and turn it on. However, do not start your vehicle just yet. Keep the key in the ‘on’ position. This action is only to provide power to the vehicle’s system. You should have your ABS light illuminated at this point.
2. Press the gas pedal 3 times
Once all of the lights are illuminated on the dashboard, including the ABS light, press the gas pedal 3 times. There is no clear information on why you have to press the gas pedal in order to activate the ABS system. But, I’ve tried it and it worked for me so please do it yourself.
3. Start your engine
At this point, the ABS system reset process is completed. Hopefully, this will reset your ABS system light. Performing the previous steps allows the vehicle main computer to reset all of the error data associated with the ABS and gather new data. Your ABS system parameters will realign and begin working properly.
1. Failed Speed Sensor
The most common cause of ABS light illuminating on your dashboard or instrument cluster is a failed speed sensor. You can check the condition of the speed sensor by performing an inspection. This inspection can be done with your tire still attached to the vehicle.
2. Damaged Magnetic Sensor
As the wheel spins, your magnetic ring communicates with your speed sensor and your speed sensor sends that data to the onboard computer. All four tires have to have the exact reading which means all four tires have to be spinning at the same speed.
3. Blown ABS Fuses
Most vehicles have three ABS fuses. If one of those, or all three fuses are blown, you will definitely see an ABS light on your vehicle’s dashboard. Locate the fuse box in your engine compartment. Open up the fuse box cover and flip it. You will see that on the inside of the cover there is a scheme of how the fuses are set up.
4. Bad ABS Control Module
I have placed this most common cause as number four because it is the least likely. However, in the event that you have completed all the first three steps and/or replaced all the parts and your ABS light is still on, it’s very possible that your ABS control module needs to be replaced.
Step 1 - Remove The Wheel

Step 3 - Remove The Sensor
- With the bolts out, you can pull out the sensor. Be careful, however, as the line to it will be held in place by another two bolts. These will also have to be found and removed before you can undertake this ABS repair.
Step 4 - Clean The Sensor
- Now you have the ABS sensor in your hand, you can begin cleaning it. Use clean rags to take off the road dirt and grime. You’ll see that this is quite heavily caked over the sensor. Don’t use any kind of chemical cleaner on the ABS sensor. If you want to use something liquid, take a bucket of soapy water for cleaning then rinse off with cold, clear water, giving the sensor time to dry after. …
