Unhappy abs and traction lights

i got my 2000 ssei about three months ago and i love it dearly. i got it knowing there were a few problems with it, one being the abs and traction control lights were on an it says service stability system. so i figured it was the wheel speed sensors going bad because i knew it needed wheel bearings. i replace both wheel bearings and to my surprise it didn't fix the problem. what stumps me is that a few weeks ago before i replaced the wheel bearings we got a lot of snow, and the entire night my trac control worked and my abs worked wonderful. but only for the one snowy night.

any help is appreciated

Check your brake fluid level. It'* a long shot but if the level is low it could see that as a possible ABS problem.

Check the rear brakes. There is a sensor for each wheel there as well.

Try unplugging each sensor, one at a time and see if it makes any difference.

They can be. The only true way of knowing is to have the dealer use a Tech II on it, and that'll tell you what the problem is. Problem is finding a dealer who doesn't charge an arm and a leg to spend 15 minutes scanning it.
