Abstract: An electronic module includes a Printed Circuit Board (PCB) which contains a plurality of circuit elements. The electronic module is electrically connected to other electrical components in a vehicle by a connector. The PCB is contained within an electrically conductive housing which includes a box and a cover. A ground trace printed on the PCB extends to a mounting hole in the PCB and provides a ground path for the circuit elements. An electrically conductive metal ferrule which elevates the PCB above the box and the cover above the PCB, extends through the mounting hole in the PCB and contacts the cover and box when the cover is fitted onto the box. A mounting bolt extends through the cover inside the ferrule through the box and into a nut mounted into a metal portion of the vehicle.
