So a few days ago I was driving back home and I went to stop in a McDonalds parking lot and my ABS light came on. I turned the truck off and then when I came back out and started my truck it was off but came back on while I was driving. It has been on ever since then.

Another thing is my brake pedal will shake start to shake sometimes whenever I press it down. I have been searching on here for a while and can't seem to find anything about it.

Does anybody have any ideas?

 

You're gonna have to find out what codes are present in the ABS module before anything else.

 

So I am guessing I am going to have to go to the Ford dealer and have them look at it? The ABS light wasn't on today but the brake pedal was still shaking some when I hit the brakes.

 

yes you will have to find out what the codes are before anything...odds are it may be a speed sensor or something like that causing unwarranted ABS activation(the shaking in the brake pedal)
