With an intuitive UI design, you can quickly access OBDII diagnostics, I/M readiness checks, DTC search, and setup options. No need to read a manual—this user-friendly auto diagnostic code scanner is perfect for beginners, mechanic and seasoned users alike.
- ENHANCED OBDII DIAGNOSTICS – Comprehensive System Testing. This engine obd2 scanner diagnostic tool offers advanced diagnostics, including testing of O2 sensors and EVAP systems. Perform a leak test on your vehicle's EVAP system and monitor the fuel tank's integrity. The O2 sensor test helps fine-tune the air/fuel mixture, improving fuel efficiency and reducing emissions—saving you money at the pump and reducing your car's environmental impact. !!! Note: The AD410 is only an engine code reader, it DOESN'T support other systems such as ABS, SRS, Transmission and others.
- EASY TO USE – Locate the vehicle’s OBD-II port (typically found under the steering wheel, near the dashboard, or inside the fuse box). Insert the 16-pin connector firmly into the port to ensure a secure physical connection. Power on the vehicle (some devices require the engine to be running, while others only need the ignition turned to the ‘ON’ position)—then the item will work. The USB cable is only for updates and is not needed when connected to the vehicle.
- CRITICAL FUNCTIONALITY – Quickly Read & Clear Fault Codes. The obd2 scanner diagnostic tool quickly reads and clears stored emissions-related codes, pending codes, and provides code definitions. With over 42,000 built-in DTC lookups, you can easily identify faults without the need for Google searches. Reset the MIL, check monitor readiness before smog tests, and understand your vehicle's health before costly repairs. !!! Note: Fault codes can be cleared after resolving the underlying issue, the code reader itself does not have a reset function.
