How do I reset my OBD2 scanner to factory settings?
Quote from AutoFixerMike on June 21, 2025, 11:25 amI recently purchased an OBD2 diagnostic tool but I accidentally changed some of the settings while exploring the menu. Now I want to reset the OBD2 scanner back to its factory default settings. I couldn’t find a clear option in the manual. Does anyone know how to perform an OBD2 scanner factory reset? Any tips would be helpful.

1️⃣ Menu Reset (for most handheld OBD2 scanners):
Plug the scanner into your car’s OBD2 port and turn the ignition ON.
Go to the main menu and navigate to Settings or System Setup.
Look for options like Factory Reset, Restore Defaults, or System Reset.
Select the option and confirm the reset.
The scanner will usually restart automatically.
2️⃣ Advanced Android-based scanners (like Autel MP808, MK808Z):
Some advanced scanners may not have a direct “reset” option.
You can perform a firmware update or software reinstall from the manufacturer’s website or using their PC suite.
Updating the firmware often restores the device to factory defaults.
3️⃣ USB / Software Update Method:
If your scanner supports USB connection, connect it to your PC.
Visit the manufacturer’s website, download the latest update tool, and follow the instructions to update or reinstall the firmware.
This process will typically reset your scanner settings.
