    ebay...abs module rebuild. costs about 125 to fix. note: when both lights are on, your ABS brakes do not work.

    new mod list: 5.3, gears/posi, mufler and tune : (

    tuned for the gears. Yeah i don't like not having the abs brakes especially in the rain. I just need to take it to the chevy dealer. I work at a ford dealership and we don't have the scanner for abs on chevy

    Even with a retune for the gears, some trucks still will throw the occasional ABS/Brake light. Mine did it, and others on GMFS will say the same.
