An industry change in protocol from OBD II to Controller Area Network (CAN) has begun. In order to perform diagnostics on a vehicle that uses the CAN interface, you will need the Tech 2 Flash and a CAN diagnostic interface module.

The CANdi module connects between the Tech 2 Flash's diagnostic link cable and the OBD adapter. Once the CANdi module is connected, it can be used on all GM vehicle applications, even those vehicles using other platforms such as OBD I and OBD II.Includes the CAN diagnostic interface module and instruction sheet.
