This is a 2000 Infiniti I30 that I am having problems with.

Saturday I changed all four rotors and brake pads..everything was fine. I drove around town and on the highway with no problems.

Two days before that, i went to Nissan to get the brakes powerflushed....didnt have any problems there either.

This week on Monday I got my new wheels and tires mounted and balanced and put on. Afterward i drove home with no problems. I went to Taco Bell after my girlfriend and friend came over...no problems. Left Taco Bell and was about to get on the highway and the ABS light came on. I drove about 15 miles on the highway and once I turned the car off and back on, the ABS light went off.

When i started driving again, the light was off for a couple of minutes then came back on. More times than not, the light is off for the first few minutes of driving then comes on. I am not braking hard, just normal city driving. When i get on the highway, it always comes on.

I do not have any check engine light. I do not have any problems with my speedometer. The only thing is the ABS light comes on. Where do I start to look? I didnt notice any sensors while doing the brakes. I didnt notice any wires hanging or anything...anyone have any ideas? It would be much appreciated!

Look in the stickys, there is a procedure for pulling the ABS codes so you can tell exactly which sensor it acting up. It involves jumping a pin on the diagnostic port.

 

Are the new rims u put on bigger than the stock rims? That could affect ur ABS and prematurely set it off.
Also do what NmexMAX said and check your wheel speed sensors on each wheel.

 

I went from the stock 16's to 19x8.5 in the front and 19x9.5 in the rear. 215/35 tire in the front and 225/25 tire in the rear.

I will check the sensors this weekend, but i dont know exactly where they are located. I already had the rotor and pads off and didnt really see anything. Then again i wasnt really looking for it because i was trying to diagnose another problem.
