The hazard
Certain heavy duty trucks equipped with Cummins ISC engines. Diodes contained in the pre-heat circuit of certain engine wiring harnesses were not properly insulated during the harness manufacturing process. This lack of insulation could allow the diodes to contact each other leading to a short circuit and possibly a vehicle fire. Correction: Dealers will inspect the harnesses and remedy, if required, by properly insulating the diodes.
