Abstract
A novel diagnostic system for a trailer is provided by the present invention. The trailer includes a micro controller which is part of an anti-lock brake system of the trailer. A warning light is provided on the trailer and is in electrical connection with the micro controller. A switch is provided proximate to the warning lamp. The switch can be activated by a technician to provide a short across the warning lamp. A stored program within the micro controller recognizes the short and performs a diagnostic function in response thereto by flashing the warning lamp in a predetermined manner.
