ABSTRACT:
A trailer electrical monitor function is implemented into a microprocessor based truck tractor and trailer electrical communication system where a programmable memory unit connected to a trailer electronic control unit is used by the trailer electronic control unit to store a trailer identification code, the result of which is connected through an interface circuit to the trailer electronic control unit where the result is then transmitted to a tractor electronic control unit and/or to an external programming unit. The tractor and trailer electronic control units control the state of a plurality of switching devices to establish the appropriate electrical connection into and out of a standard seven pin tractor/trailer electrical connector where high speed data communication links are used for control diagnostics.
