A method for vehicle diagnostics includes receiving vehicle information from a vehicle computer system and identifying, at the data processing hardware, at least one vehicle module from the vehicle information. The at least one vehicle module represents a detected fault of the vehicle computer system. The method also includes executing a diagnostic program configured to display on a display screen a graphical user interface having a fault topology window associated with at least one detected fault of the at least one vehicle module. The fault topology window has a vehicle information panel and a fault topology view panel. The diagnostic program is configured to receive a detected fault selection input of the at least one detected fault of the at least one vehicle module and display a fault topology view of the at least one detected fault of the at least one vehicle module.
