1. A diagnostic tool, comprising:
- an interface configured to be communicatively connected to a vehicle computing system via a communication protocol;
a transceiver electronically connected to the interface; and
a voltage threshold controller configured to adjust a voltage threshold within the diagnostic tool based on the communication protocol by controlling a plurality of impedances and a plurality of voltage levels of the transceiver with a plurality of switches, wherein the plurality of switches is connected to the voltage threshold controller, the plurality of impendences, and a plurality of reference voltages, the plurality of switches further controls a current level in the transceiver, and wherein the transceiver is configured to automatically detect the communication protocol with the voltage threshold controller by reading one or more bit patterns from the vehicle computing system.
