False ECM and /or ABS codes on Dodge Sprinter 3500

False or unrelated trouble codes in the engine control module (ECM) and/or anti-lock brake module (ABS) may be caused by a brake light bulb issue or corrosion in the bulb socket or trailer harness connector. Our technicians tell us all bulbs should be inspected for correct function and application. Also, all related sockets, connectors, and circuit boards should be checked for corrosion if this issue occurs.
