ABS Light on In Your Car or Truck? Is it Bad Brakes, or Can it Be the Wheel Bearing's Fault?

Does your car or truck have an ABS light on, even though the brakes feel fine? In this video, Sue explains how more than brakes can trigger an ABS light, shows you why, and what you can do to get rid of the light on your car or truck! Check out the video to see how axles and wheel bearings can also play a role in making the ABS light come on!

My ABS light went on and I thought it was the ABS system. It turns out to be the wheel bearing that was worn out. When ABS light turns on first check the wheel bearings, it will save you a lot of money.

Can a wheel bearing cause the “BRAKE”, ABS, and traction control light to all come on at once?

This lady has got it all over most of the "Men" that are basically trying to sell some gimmick on YouTube. She is a great teacher, and explains things in plain English without the confusion. Thanks for the video!

Why don’t the ABS tell the ECU which tire is affected as well? We are living like fred flintstone still

[DanTriggerhappyGames]

Absolutely love the detail you go into, it's always a relief when your video pops up for an issue I'm trying to solve, much appreciated!

I had an ABS light come pop up on my 86 BMW 325 es. I was fortunate enough to run into a BMW mechanic who was doing side work ln the street and he pointed me to the left front wheel bearing area. I also remember having no breaking issues and he remarked that on my particular model it was a common problem. I unscrewed the old one put in a new one and the ABS light went off. I am no mechanic but always thought it to be a good idea to get a service manual for every car I had. Now with YouTube you really don’t need to buy one. Thank you for the video.

If your brakes work fine, 1st thing is to check your ground straps. GM/Chevy have 4 and if it's 4x4 they have 5 ground wires

My abs light was due to bad bearings. Put a new hub on and it was good to go.

What if you can't afford to purchase/replace $5, 000 in parts just looking for the problem?

This video was very helpful. I’m actually dealing with an issue like this at my job and I replaced the wheel speed sensor because there wasn’t one on there and then come to find out it’s the eccentric ring that was broken. This video was very helpful.

I love this lady she is very talent and smart learning a lot from her

Great job ! The speed sensor returns a voltage which is proportional to the wheel speed and the voltages from all the wheels have to be in the same range. It uses a magnetic circuit where there is a magnet inside a coil and when the reluctance wheel rotates it deforms the magnetic field with each tooth of the gear (not a gear but may look like one) This causes a back and forth current in the coil which is read as an AC voltage that is proportional to wheel speed. Pretty cool !!

My mom came to me because her abs would activate every now and then when she would brake, I took a look at it and there was rust jacking under the speed sensor. Cleaned it up and put some paint over the bare surface, problem solved (02 trailblazer)

I just bought this 2004 Suburban and I noticed the brake/ABS plug underneath the front passenger seat was unplugged. Soon as I plugged it up the 2 front brakes passenger /driver started dragging. I wonder if the previous owner unplugged the plug for that reason. To release the brakes I opened up the bleeder screw. And when I changed the brakes both passenger/driver side brakes was to the metal. Can having the ABS plugged up cause the brakes to drag? Leaving it unplugged will it help stop the dragging?

Im gonna assume my abs light turned on due to my cv axle being two peices. Lets hope so at least…

No ABS parts (speed sensor) come up to my 2006 Lincoln Navigator.

I have and 05 Saturn Relay/Chevy Uplander a few years ago a mechanic replaced my CV joints and wheel bearing and hub, and when I drove home this ABS light was on, wasn't on before the new wheel bearings. Anyhow I watched the Scotty Kilmore channel about it he says if the ABS light is on means your ABS system won't operate but your vehicle will still stop.

It's been on for over two years, last week I had my front brakes and rotors serviced by a mechanic he replaced all of the brakes and just mentioned that my ABS wasn't operating but didn't suggest me to bother repair it.

To date vehicle is riding ok the light is on but seems to stop. If it's just and expensive sensor then maybe I will check the wrecker yard to see if I can get a few there.

Wooow I just realized what the issue is with my Burban and why the back tire sometimes sounds like my brakes are sticking.i think my back wheel bearing is going out but not completely out

[BeinnMac]

Great information for people. This helps explains the problems with ABS noticeable
