This may be caused by one of the wires in the ECM harness being chafed or cut. Due to the cause of the condition, and the positions of the wires in the harness, it is unlikely that more than one circuit will be affected.
The condition may be caused by the ECM wiring harness rubbing on the ECM bracket.
Inspect the ECM harness (off of the Engine Control Module X1 connector) for any damage and repair any wires found. After the repair is completed, wrap Woven Polyester Electrical Tape (PET) or equivalent anti-abrasion tape around the wires on the harness.
