(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)
