An exemplary method detects signal voltages on the communication bus that are indicative of a ground offset condition, and saves voltage timestamps for the detected signal voltages such that each detected signal voltage has a respective voltage timestamp. Message timestamps are added to messages on the communication bus, such that each message has a respective message timestamp. The message timestamps are compared against the voltage timestamps to identify at least one of the electronic devices as a ground offset source."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Determining the source of a ground offset in a controller area network","description":"Disclosed herein are a system and a related computer-executed method of locating a source of a ground offset in a network of electronic devices interconnected by a communication bus.
