ABS problem

If you have a programmer that can read or adjust for tire size/ speedometer etc..like a smarty, hook it up and try to connect and adjust ABS options (you do not have to adjust anything). If the programmer shows "unable to connect" the ECM is unable to communicate w/ ABS control module- this could be a bad power or ground, or if you have any accessories running off of the ABS power module fuse in the fuse box it can lead to what you have going on. If none of the above applies to you, you can reset the ABS module- disconnect battery cables, pull the fuse box, remove all connectors from bottom of fuse box, let it sit for a long while, reconnect everything and give it a try. I had the same issue a while back, new trans and rear end sensor did nothing, dealership didn't have a clue. Good Luck
