I upgraded my rear gears to a 410 from a 342 in my silverado 01. My abs and brake light keep coming on even after I tuned the truck with my programmer. My question is does anyone else have this problem and if so what did you do to correct it, change out the abs brake module?
what programmer u using? i have a 05 5.3 went from 3.23 to 3.73.. I had to have it programmed by Nelson Performance or all my stuff would come on too. I would ditch the programmer... His mail order tune was better than my Bullydog GT(when i programmed it with it the lights wouldnt come on either btw)..
Yeah a complete tune will take care of that for you, also any gm dealership can do an abs recalibration and correct it however I would spend the money on the tune from nelson it makes more sense.
