This is a known problem and there is/was a TSB 03-05-008 PIC3500


In short check the wiring harness it passes under/around the front of the transmission side cover. GM reports that harness chafing can occur in that area because the powertrain flexes on its mounts. Check the harness for any signs of chafing. Next, examine the area near the A/C dryer canister where the ABS harness splits. The harness can chafe right at the dryer canister bracket. If you find chafing, remove the harness and repair the damaged insulation with heat shrinkable tubing.


After the repair you may have to reset/clear the ABS codes with a scanner, the engine codes also ...though the engine codes can be cleared with a NEG terminal disconnect. Advisable to clear all modules with a scanner as some will remain in them even the BCM
