The one or more non-transitory computer-readable storage media of claim 6 , the operations comprising, based on the transmission of the information on the firmware version of the electronic control unit of the vehicle, or the information on the safety limit configuration of the vehicle, receiving, through the communication circuit, at least one notification indicating that the vehicle is in the abnormal state.
8 . The one or more non-transitory computer-readable storage media of claim 7 , wherein the safety limit configuration of the vehicle configures the vehicle to limit digital media broadcasting (DMB) display within the vehicle, and/or navigation input functions during operation of the vehicle.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application is a continuation of U.S. patent application Ser. No. 16/980,895, filed on Sep. 15, 2020 and assigned U.S. Pat. No. 11,645,878 issued on May 9, 2023, which is a continuation of PCT International Application No. PCT/KR2019/003699, filed on Mar. 29, 2019, which claims priority to Korean Patent Application No. 10-2018-0038226, filed on Apr. 2, 2018 in the Korean Intellectual Property Office, the disclosures of which are herein incorporated by reference. TECHNICAL FIELD Various embodiments relate to an electronic device and a method for diagnosing a vehicle. Background Art An OBD (on-board diagnostics) is a device which enables a driver or a mechanic to check and inspect whether or not a vehicle is abnormal by lighting a malfunction indication lamp (MIL) on an instrument panel in a case that a problem occurs in the vehicle. Examples of an OBD include OBD-I and OBD-II. OBD-I determines a failure due to disconnection/short-circuit of various input or output sensors connected to an engine control unit (ECU), and OBD-II diagnoses rationality and performance of a sensor and whether or not a system is normal as well as a disconnection/short-circuit. Such an OBD is mounted to the front dashboard side of a currently released vehicle. Since an OBD may be mounted to a vehicle and perform self-diagnosis of the vehicle, a vehicle repair company or a vehicle insurance company can usefully use an OBD. In addition, an OBD enables a driver's driving habits to be determined, so that the driver can fix the driving habits or safely drive a vehicle, based on feedback provided by the OBD. An OBD may acquire vehicle state information from an ECU of a vehicle. For example, an ECU, which monitors vehicle information through a plurality of sensors in a vehicle, performs communication with an external device of the vehicle, and through such communication, an OBD may acquire, from the ECU, vehicle state information such as vehicle fuel efficiency, revolutions per minute (RPM), a speed, a fuel usage status, a vehicle accident or failure, a battery and consumable status, and a driving time. DETAILED DESCRIPTION OF THE INVENTION Technical Problem The number of ECUs in a vehicle continuously increases with the development of the vehicle, and ECUs are developed differently for different vehicle versions (different engines or transmissions, various options, nationally different versions country by country, and the like). As the number of ECUs mounted to a vehicle increases, the risks due to illegal tuning or mounting of ECUs are increasing. Accordingly, there is a demand for a measure of detecting the state of an ECU mounted to a vehicle. According to various embodiments, an electronic device and a method for diagnosing a vehicle, by which safety of the vehicle may be determined using information acquired from the vehicle, may be provided. Technical Solution According to various embodiments, an electronic device may include: at least one communication circuit configured to provide communication with a vehicle device or an external electronic device: at least one processor electrically connected to the at least one communication circuit; and a memory electrically connected to the at least one processor, wherein the memory stores instructions configured to cause the at least one processor, when executed, to: when connected to the vehicle device, acquire and store first information related to the vehicle device: in a case that the electronic device satisfies a designated condition, acquire second information related to the vehicle device from the vehicle device; based on the first information and the second information, determine the state of the vehicle device; and based on the determination, perform a designated operation. According to various embodiments, an electronic device may include: at least one communication circuit configured to provide communication with a vehicle device or a first external electronic device: at least one processor electrically connected to the at least one communication circuit; and a memory electrically connected to the at least one processor, wherein the memory stores instructions configured to cause the at least one processor, when executed, to: when connected to the vehicle device, acquire first information related to the vehicle device through the at least one communication circuit: transmit at least a part of the first information to the first external electronic device through the at least one communication circuit: in a case that the electronic device satisfies a designated condition, acquire second information related to the vehicle device from the vehicle device through the at least one communication circuit: transmit at least a part of the second information to the first external electronic device through the at least one communication circuit; and in response to transmission of the first information and the second information, receive, through the
