UDS (Unified Diagnostic Services) implementation on connected road vehicles and application on remote diagnostic
systems are discussed in this paper. The diagnostic equipment can remotely access vehicles information through wireless
connections and acquire vehicle information, such as DTCs (diagnostic trouble codes), speed of vehicle, battery voltage, engine
speed, temperature of coolant, etc. Verifications of the remote diagnostic systems at ARTC proving grounds are presented in this
paper. Finally we can conclude that the driver safety can be secured and the malfunction vehicles can be diagnosed quickly by
using wireless remote diagnostic system.
