If we are going to mention 'flash' updates here please mention the version number if you have it - also have the dealership put it on your work order for your own reference later.
Work order is still open because issue not resolved. CEL and trouble code P24B0. Dealer flashed ECM to widen limits so that trouble code would not re-appear. However, trouble code did re-appear so they have ordered a new emission exhaust sensor. My brother's Colorado gave same trouble code and when his dealer flashed his ECM - no more CEL.If we are going to mention 'flash' updates here please mention the version number if you have it - also have the dealership put it on your work order for your own reference later.
