Abstract

Methods are described herein for communications bus data transmission using relative ground shifting. A plurality of voltage lines of at least one electronic control unit (ECU) are monitored. The at least one ECU electrically coupled to a communications bus. A voltage differential across at least two of the plurality of voltage lines of the at least one ECU is measured. A pulse or data stream is injected into the communications bus via one or two voltage lines based on the measured voltage differential having an amplitude lower than a predetermined voltage threshold.
