    Solder on interior ABS electronic board breaks over time due to vibration causing this condition.
    Look up fix on u tube.
    Implemented fix and problem went away

    ABS light went on at 100,000 miles. Dealer quote was ~$2000.00. I even replaced the ABS control unit with a salvage yard part and the light is still on. Brakes work fine anyway without the ABS. Now at 250,000 I think the van has paid for itself many times over and I will retire it soon.

    Breaks are good and the ABS light is on and will not turn off. This is a defect and open the newer models don't have this problem. They want to much money for the repair.

    Just one day, I was driving and the ABS brake light came on.
    It doesn't come on everything, just mainly after the 2nd time starting if I shut off during a trip.
    I have had it looked at and they said my brakes are fine that it might be the computer module. The brakes seem to work the same, it just is the light. I did notice when I had worn tires it would need more time to stop. Hopefully Chevy will recall this problem. It sounds like others are having the same issue and should be a recall part!!!

    ABS warning light on, diagnostic ABS system controller module. Web search shows rebuilt units at $600-$800. Need to decide to live with no ABS or replace. Hoping to keep the van for several more years it's a good utility van. We only but 1-2,000 miles on it a year.
