(Need for) Diagnostics?
On-Board Diagnostic (OBD) is a function of the vehicle.
Off-Board Diagnostics is the job of the service technician …
… who uses diagnostic communication with the OBD system for troubleshooting

Diagnostic Testers, what are we talking about?
Heavy-Duty Road-Vehicle
Non-Road Mobile Machinery
External test equipment (TESTER) is connected to the Data Link Conncetor (DLC) of a road-vehicle or
NRMM via a Vehicle Communication Interface (VCI)
