【Brand New】 Dimensions: 13.7 cm length x 8 cm width x 2.4 cm height Screen Size: 2.4 inches 【Vehicle Inspection Support & Self-Diagnosis Function】 Strongly supports vehicle inspections in Japan, self-diagnoses ECU abnormalities, and efficiently identifies necessary repairs and inspections based on fault codes. It helps to pass vehicle inspections in one go by addressing emission-related system readiness and saving the time and cost of re-inspections. 【All OBD2 Functions & Troubleshooting Unknown Causes】 Equipped with 10 modes including reading fault codes, clearing fault codes, freeze frame data, live data stream, component testing, and vehicle information retrieval. Connects to the in-vehicle OBD port and reads fault codes in seconds. 【Vehicle Condition and Performance Monitoring】 Unlike visible failures such as flat tires, internal failures like those in the ECU cannot be seen with the naked eye. This device allows you to see the car's status data at a glance. Real-time engine data (coolant temperature, RPM, vehicle speed, etc.) can be visually confirmed through graphs and numerical values, monitoring the status of various sensors and components, and not missing even minor issues. 【Compact Design & Full Japanese Language Support】 The diagnostic tool has a lightweight design and a 2.4-inch color LCD screen for excellent visibility. Easily switch between 13 languages, including Japanese, English, French, and Italian. 【Wide Range of Compatible Vehicles & Excellent Compatibility】 The YM319 OBD2 diagnostic tool supports almost all OBD2 protocols: KWP2000, ISO2000, ISO9141, J1850 VPW, J1850 PWM, and CAN. It is compatible with vehicles manufactured in 1996 or later in America, 2002 or later in Europe, and October 2008 or later in Asia. *Please note that it is not compatible with Asian vehicles manufactured before October 2008, as well as Daihatsu and Suzuki models, older Toyota Crown models, and Nissan Cefiro models, which use the JOBD protocol. It is not compatible with JOBD domestic vehicles manufactured in Japan. The connector is 16-pin. The voltage is 5V-20V. This is a diagnostic tool for 12V vehicles. It is not compatible with light vehicles, motorcycles, and 24V trucks. It only supports the diagnosis of the OBD2 system, but cannot diagnose ABS/SRS/transmission systems. If you want to diagnose systems other than OBD2, you will need a higher-end diagnostic tool with the corresponding system diagnostic functions.
