Okay so today, my truck's brake and rear anti lock lights come on when starting as usual but they stay on. When I turn the truck off and back on, they are off like normal. Is this just some sort of short in wiring or is something going bad?

 

Mine ended up being a check valve in the ABS system. Your results may vary.

 

I had that sane problem I needed to replace the master cylinder any how so I did an all lights went off...like zxwut? Said it could be a different case for you.
