A vehicle switch module includes a sub-network having switches connected thereto and a sub-network controller in operative communication with the sub-network and the switches. Each switch includes a microprocessor programmed to generate switch messages that include address and switch logic state data. The sub-network controller transmits switch queries onto the sub-network to a number of switch addresses to determine a connection status and switch state of switches in the switch module and receives switch messages responsive to the queries from switches at addresses to which the switch queries were transmitted. The received switch messages verify the identity of a switch in the module and provide a switch state for the switch. The sub-network controller interprets the received switch messages and—based on the switch address and switch state data in the messages—controls operation of a vehicle output or load associated with each of the switches.
