Why Are Truck Diagnostic Adapter Cables Needed?
Many older trucks, commercial vehicles and trailers do not use the standard 16-pin diagnostic connection found on most modern vehicles.
Manufacturers used a variety of their own diagnostic connector designs, meaning a suitable adapter cable is required to connect standard OBD2 diagnostic equipment to the vehicle.
This kit provides a useful selection of the most commonly required commercial-vehicle diagnostic adapters in one set.
Compatible Diagnostic Equipment
These adapters can be used with compatible truck diagnostic scanners and interfaces that use a standard OBD2 connection, including:
- Delphi DS150E
- Autocom DS150E
- CDP+
- Other compatible OBD2 commercial-vehicle diagnostic equipment
Please note: these are diagnostic adapter cables only. They are not diagnostic scanners and do not contain diagnostic software.
A suitable diagnostic interface and truck diagnostic software are required separately.

Important Compatibility Information
These cables provide the physical connection between the vehicle or trailer and compatible diagnostic equipment. They do not add diagnostic functions or vehicle coverage that are not supported by your diagnostic interface and software.
Available diagnostic functions depend on the vehicle or trailer system, diagnostic interface and software being used.
Always check the diagnostic socket fitted to the vehicle before ordering. If you require an adapter for a particular truck or trailer and are unsure which connection is fitted, please contact Diagnostic Central before purchasing.
