The invention relates to a vehicle fault diagnosis tester and a vehicle fault diagnosis system comprising the same. The vehicle fault diagnosis tester has a command input module, a maintenance guidance display module and a wireless communication module, wherein the vehicle fault diagnosis tester is a wearable device, and the command input module is a non-contact type. The vehicle fault diagnosis system is used for a vehicle with a data link connector (DLC), and comprises an OBD dongle and the above described vehicle fault diagnosis tester. The OBD dongle can be inserted into the DLC, collect vehicle diagnosis data from the DLC and sends the vehicle diagnosis data to the wireless communication module of the vehicle fault diagnosis tester in a wireless way. The invention introduces a wearable device having a non-contact command input module into the technical field of automobile fault diagnosing, and introduces the concept of guidance maintenance into the vehicle fault diagnosing system so that the maintenance operation becomes interesting, convenient and efficient, and the maintenance personnel do not have to frequently switch between information reading and maintenance operation.
