Compatibility
Designed specifically for the TOPDON ArtiDiag900 BT.
This is a replacement communication interface and does not operate as a standalone diagnostic scanner. An existing compatible ArtiDiag900 BT tablet is required to perform vehicle diagnostics.
If you own a different TOPDON diagnostic scanner, confirm VCI compatibility before purchasing. Similar-looking TOPDON VCI connectors should not be assumed to be interchangeable between diagnostic tools.
Replacing Your Existing VCI
TOPDON provides replacement VCI functionality within the ArtiDiag900 BT software. When installing a replacement VCI, navigate to the Dongles section and use the Replace VCI function. Once the serial number of the replacement VCI has refreshed, select the new VCI to connect it to the diagnostic tablet.
Ensure the ArtiDiag900 BT software is updated before replacing the VCI.
