Brakes problem
2006 Chevy Uplander 6 cyl Two Wheel Drive 34,000 miles

While using the donut spare on my vehicle the abs light began to go on. After the donut was removed from the vehicle, this problem ended, however, it has started to go on again. I have had the brakes system checked, and there are no issues with the brakes. Could the donut confused/affected the computer's ablity, and if so, what has to be done to resolve this issue.
