Abs light has been on for 2 years & ABS does not work. Wet roads yesterday and light went out and the ABS worked. Can I fix it?

Im not 100% familiar w the vehicle, sounds like a wheel or trans bearing. Since you were talking ABS, then there is a ABS sensor & ABS Ring, Good luck, Frank M ( sounds like abs ring !?

Check with a code reader or scanner, the ABS could be at fault

If the lights went back off it means that the systems were activated due to road conditions, did their job, and then returned to their normal standby mode. If the lights remain on you need to have the vehicle's OBD computer read for trouble codes and then determine if any repairs are necessary. You can have the codes read at your dealer, your qualified mechanic, or at many auto parts stores.

I have the ABS light on. I pulled the relay to reset it. the light went out but as soon as I start moving the light comes on. I tested the ABS on a sandy road and it does work. I jacked all wheel off the ground. I rotate each wheel and found the ABS light comes on when rotating the rear left wheel. I removed the rotor to examine the the system. I cleaned it with the brake cleaner I still get the ABS light on after rotating the wheel. Is that the sensor that is bad?

The most common problems associated with the ABS light coming on it a broke ABS speed sensor harness, or a faulty sensor itself.
You can try looking under the vehicle by the wheel bearings and see if the ABS harness is broken, but otherwise it will be nearly impossible to know which sensor is malfunctioning unless you get it scanned.
Your brakes will still work fine, just on wet or slippery roads the ABS won't engage until the problem is fixed.

You can try unpluging the fuse under the hood for the ABS but your brake light and ABS light on the dash will come on.I'm in NH and it would fail the saftey inspection if either of thoughs lights were on during the inspection.See if this helps your problem but you most likely have a wheel sensor going bad in the ABS system.

These are extremely complex systems and more likley than not, there is nothing wrong with the abs system. If you don't feel a pulsing force against your braking foot pedal, than you've got nothing to worry about than getting the dealer to clear the code in the abs control box. Again, if you feel NO changes in your braking system what probably happened is when you hit the bump/pothole one of your wheels went slightly faster than the one opposite it and the abs kicked in for a split second therefore storing a code.

Hello,
It sounds like the wheel speed sensor may have been damaged in the process of removing the tire. That would cause the abs light to come on. Ususaly when the abs light comes on it is a sign they won't opperate as abs but only as standard hydraulic brakes. I hope this helps. If you have more questions reguarding this or other conserns please ask me. Please remember high ratings are very important to me.

Thank You,
Roy
