Frequently asked questions

Does the AD600S work with every car?

No. The listing claims broad make and model coverage but says menus and functions vary by vehicle, and AutoVIN does not work on all cars. Check compatibility for the specific make, model and year.

Which systems and reset functions are listed?

The listing describes four-system diagnostics and nine resets: oil, steering angle, battery management, throttle adaptation, DPF regeneration, ABS bleeding, TPMS, electronic parking brake and injector coding. Availability depends on the vehicle.

Can it diagnose parking sensors?

No. The listing specifically says parking sensors, part of the parking-assistance system, are not supported.

Does it need Wi-Fi to scan a vehicle?

It is listed as corded electric. Wi-Fi is mentioned for software updates, not as the vehicle connection. Customer feedback on Wi-Fi update connectivity is mixed.
