Device ”is Korean Patent No. 10-0917442. In addition, an example of a technology for diagnosing a vehicle failure by receiving output information wirelessly from a diagnostic terminal is titled "Portable Wireless Vehicle Failure Diagnosis System", which is Korean Utility Model Registration No. 20-049137.

However, the above-described prior art requires expensive diagnostic equipment specifically designed to be suitable for professionals in the vehicle repair shop, and thus, there is an economic burden, and there are functional limitations in not properly performing vehicle control functions such as remote start or alarm sound.

Recently, research has been conducted on products that provide diagnostic information by short-range communication between a diagnostic device having a Bluetooth communication function and a smartphone connected to a diagnostic terminal. Using smartphones like this can provide relatively inexpensive service, but there is a limit that the previously released vehicles are excluded from service due to product development only for new cars manufactured recently, and Bluetooth communication with narrow communication range As the standard is applied, vehicle diagnosis and management cannot be properly identified in a distant state, which limits the service area.
