User-friendly design: supports 10 languages: English, German, French, Spanish, Italian, Russian, Polish, Chinese, Japanese and Portuguese. The clear 2.4 inch TFT screen is clear. The 1 metre long cable made of flexible, insulated material ensures comfortable handling and increased safety. Powered directly from the vehicle's data port, so no batteries or a separate charger are required.
Precise Monitoring and Analysis This engine code reader provides advanced diagnostic functions, including lambda sensor. It performs leak tests of the vehicle's evaporation system and monitors the integrity of the fuel tank. Lambda sensor testing helps to improve fuel efficiency, save fuel and minimise the environmental impact of your vehicle. The device is not only portable, but also provides precise and fast results.
Improved 2-in-1 OBD diagnosis: the OBD plug tester offers professional OBD functions. The updated version has a database of up to 35,901 DTC error codes, while the older OBD2 model typically contains only 3,000-10,000 DTCs. Thanks to the new operating system and improved hardware, it can easily determine the cause of the check engine light and read and clear the vehicle diagnostic error code in seconds.
Important note: This diagnostic tool for all vehicles is designed exclusively for engine system diagnostics. It cannot diagnose non-OBDII systems, including ABS, airbag, SRS, etc. If you delete the error code directly without repairing the car, and find that the error code is still present, your car is still a hardware failure. We recommend that after reading the error code, first fix the car problem and then delete the error code.
Comprehensive Vehicle Compatibility This OBDII/EOBD reader supports nine standard protocols and is widely compatible with most petrol vehicles that meet the ODB2 standard: US models from 1996 onwards, EU models from 2002 and Asian models from 2008. Note: It is not compatible with vehicles with alternative drives or hybrid vehicles. Always check compatibility with your vehicle model before purchasing.
Advanced OBD11 Functionality This versatile diagnostic supports 55 manufacturer protocols to locate check engine light problems. Features include reading and erasing DTCs, retrieving vehicle information, viewing live data streams, access to freeze frame data, check I/M readiness monitors, performing O2 sensor tests, battery voltage tests, viewing real-time charts and EVAP system tests.
