    ABS Light on - What to do after testing

    Hello,

    My ABS light came on today on the way to work. When i left, the light shut off affer engine start, and came back on again after starting to move. So its not the ABS relay that i read up about.

    I did the "1 sensor at a time" method that I found below, and for every sensor "tested" the ABS light just stayed on through key on, crank, and engine start. Driving the car didn't turn the light off.

    What could it be? Bad ABS computer?
