Abstract

A system and a method for determining a bus address for a controller within a network are provided. The method includes coupling a first set of pins of a wire harness connector to a second set of pins of a PCB connector of the controller. The method further includes sampling voltages of a portion of the first set of pins of the PCB connector to determine a wire harness ID utilizing a microprocessor. The method further includes accessing a look-up table from a memory device to select the bus address for the controller using the wire harness ID utilizing the microprocessor. The look-up table includes a plurality of bus addresses correspondingly associated with a plurality of wire harness IDs. The method further includes storing the selected bus address in the memory device utilizing the microprocessor.
