An automotive diagnostic tool includes an antenna, a speaker, and a controller. In response to a vehicle diagnostic request, the controller generates a carrier frequency that corresponds to a predetermined frequency associated with electromagnetic emissions from an imbalanced differential channel in the vehicle. The controller alternately enables and disables the differential channel resulting in an audio signature and a baseline audio signature. The controller demodulates signals from the antenna based on the carrier frequency and outputs the demodulated signal to the speaker for analysis by a listener. The demodulated signal may be further processed by the controller to identify emissions from the communication network.
