Driving to work this morning my ABS light came on when I was on the expressway and stayed on until I reached my destination. When I turned the truck on to leave work it stayed on until I went a few blocks and had to slam on the brakes when a car pulled out in front of me. It went off immediately and has not went on since. I checked the relay, fluid, lights, etc and nothing is wrong. Is this a sign that the control module is going bad?

 

It's called a "glitch". A natural part of computers !! I've had various types - on and off for a while then stops ! You should be able to feel some of the things working , tires slipping etc .If things feelOK don't worry about the lights.
