FAQ

1. How to update the KONNWEI OBD scanner?

To update your KONNWEI OBD scanner, connect the device to a Windows PC using the USB cable included in the package. Before connecting, press and hold any button on the scanner, then plug the USB cable into the computer. The screen should switch to Update Mode.

After that, download and install the official Uplink update program on your PC. The update tool can usually be found on KONNWEI official support resources. Once the program is launched, it will search for the latest available software version, download it, and complete the upgrade process automatically.
