This course provides a working knowledge of electronic control systems on heavy duty trucks and mobile equipment. Course topics include the operating principles of interactive electronic control systems, on-vehicle networking systems, sensing circuits, and actuation devices. An emphasis will be placed on the use of electronic diagnostic tools to properly diagnose and maintain computer management and CAN Bus systems. Hands-on exercises target the identification, location, and testing of electronically controlled mobile equipment systems. Participants will also practice using diagnostic software to troubleshoot and diagnose failures of electronic controlled sensing and actuation circuits.
