An apparatus and method are provided that allow a diagnostic tool to communicate with a data link connector in a vehicle and place the vehicle in a desired state for diagnostic testing. A cable that can automatically multiplex its connections in order to make the appropriate connections between the diagnostic tool and the data link connector based on a communication protocol of the vehicle under test. A connector allowing for selective switching of pins of the connector to jump connect the selected pins. This allows the vehicle to be placed in the proper state for diagnostic testing and the diagnostic tool to communicate with the data link connector regardless of the pins being used by the communication protocol of the vehicle.

Multiplexing device with provision for expansion

An integrated circuit vehicle diagnostics interface adapter includes a semiconductor substrate with two integral gateway conductors. A set of paired switches on the substrate link any two of a first set of contacts to the gateway conductors, and another set of paired switches on the substrate link the two gateway conductors to any pair of a second set of contacts corresponding to a particular vehicle network communications protocol circuit in a vehicle diagnostics device. Both sets of switches are controlled by an integrated switch control module.
