ABSTRACT:
A vehicle diagnostic system monitors user-selected analog diagnostic data that is received from a vehicle to determine whether it meets a user-specified trigger characteristic and records user-selected digital diagnostic data that is received from the vehicle in response to a determination that the trigger characteristic has been met. The user-selected monitored diagnostic data may instead be digital and the user-selected recorded diagnostic data may instead be analog. The user may make both selections from a set of analog and digital diagnostic data types. Other features, objects, benefits, components, methods and variations are also disclosed.
