Universal 9-pin J1939 to 16-pin OBD2 Adapter Cable – Commercial and Work Vehicle

The universal 9-pin J1939 to 16-pin OBD2 adapter cable is an industry-standard adapter essential for diagnosing heavy commercial vehicles, such as trucks, buses, agricultural and construction machinery. These vehicles use the SAE J1939 communication standard, accessible via a robust, round 9-pin “Deutsch” connector. This port, usually black (Type 1) or green (Type 2), differs from the standard 16-pin port used in the automotive sector.

This adapter cable acts as a physical bridge between the J1939 port and the OBD2 interface of a universal or brand-specific truck scanner. This allows technicians and fleet managers to use one scanner to read different vehicle types. The cable is suitable for use in heavy-duty work environments such as workshops, depots, and construction sites.

Application and functionality:

The cable enables CAN-bus communication between J1939 systems and OBD2 diagnostic tools. Once connected, the user can, among other things:

• Read and clear fault codes from systems such as engine, transmission, ABS, and body control
• Read live data: engine speed, turbo pressure, temperature, fuel consumption
• Perform service procedures: DPF regeneration, component calibration

The adapter cable is usually compatible with both Type 1 (black) and Type 2 (green) connectors. Type 2 is backward compatible with older systems.

Compatible with the following vehicle brands and models:

This adapter is universally compatible with virtually all heavy vehicles and machines equipped with a SAE J1939 port. This includes, among others:

• Trucks: DAF, MAN, Scania, Volvo, Renault, Mercedes-Benz, Iveco, Cummins, Freightliner, Kenworth, Peterbilt
• Buses & coaches: Van Hool, VDL, Setra
• Agricultural vehicles: John Deere, New Holland, Case IH, Fendt
• Earthmoving and construction machines: Caterpillar (CAT), Komatsu, Volvo CE
