Every light possible came on.
 

Last night, I test fitted some 18's on my car and left my 17's the as well. I drove about 3 miles to make sure there was no rubbing or anything driving on the road. When I was on my way back to out my 17's back on every light came on. Check engine, electronic steering, ABS, traction control, and the brake light as if I had the e-brake on. Once I put my 17's back on all of the lights turned off except for the check engine light. So now my check engine light is on and my cruise control doesn't work. When I went to turn the cruise control on the light was orange instead of green. Anyone have any ideas?

Wonder if the wheels through off the speed sensors in the car which might be the reason cruise light is orange. Could the OP disconnect the battery and reset everything??

What size are the 18" tires?

D thissen im not sure, but I will try that when I get home.
