The auto-diagnostic code scanner is well connected to the vehicle's on-board system. The connection time is quite short. I searched a lot for the scanner for car and engine diagnostics and many did not like me for various reasons, some were cheap and not practical, others were too expensive and complicated. This scanner corresponds to the price, the set of functions and the quality at the highest level. I immediately liked this scanner, I will often use it and it will always help me with various problems in my cars.
