Today as I went to get lunch from work. I got into my truck, started it up. The ABS light came on like normal. But instead of the light just blinking on once and going out, the light stayed on. Then the light went out after a little less than a mile of driving. The same thing happened when I left work. Is this normal? I don't think so. I have owned the truck for eight years. By the way the truck is a 1995 2wd with four wheel ABS.
