    My partner at work has a 2001- 5.3L- 4X4 Suburban that throws a ABS light at times. He took it to the Chevy Stealer and they cleaned and dielectric greased all the connections and scanned it.
    They say bad computer,$1,300 to replace. He has no book on the truck. My question: is the computer separate from the controller, in the main CPU of the truck or it's own separate computer? His wife just had their first baby so the hormones are making her freak out. I told them it should be fine , you just don't have the ABS function when the light is on. It only has 60k on it and is paid off

    ABS module should be seperate from the main PCM. Should be on the inside of the left frame rail, looking underneath the truck.

    My truck has the same issue- I'm going to try re-grounding it in the next couple days as I understand this can cause the ABS comp to "think it's dead." My ABS has been having issues since June of last year, I've just been living with it. Truck brakes just fine- just no ABS.
