The ProFormance Link is a wireless Bluetooth adapter that connects your diagnostic tool to your vehicle's OBD-II port. It enables real-time data streaming, fault code reading, and ECU communication without cables.

ProFormance Link supports most diesel vehicles with a standard OBD-II port (2008 and newer), including:

• Heavy-duty trucks (Cummins, Detroit Diesel, Volvo, PACCAR)

• Construction and agricultural equipment with J1939 protocol

For older vehicles or non-standard protocols, contact support for compatibility verification.

4. Go to Settings → Device → Connect New Device
