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.
