Introduction to OBD to Type 2 J1939 9 pin and 6 pin J1708 splitter Y cables

The OBD to Type 2 J1939 9 pin and 6 pin J1708 splitter Y cable is an adapter cable used for diagnosing heavy-duty vehicles such as diesel trucks. The following is an introduction to it:

Function and purpose

Protocol conversion: This cable can convert the 9 pin J1939 port and 6 pin J1708 port to the 16 pin port of OBD2, enabling OBD2 diagnostic tools that support J1939 and J1708 protocols to communicate with heavy-duty vehicles with corresponding ports, thereby achieving functions such as vehicle fault diagnosis and data reading.

Applicable vehicle models: commonly used for 2013 and newer medium and heavy-duty trucks and equipment,  The types and configurations of diagnostic ports vary among different brands and years of vehicle models, and this cable can be adapted to various common heavy-duty diesel engine models.

Structural characteristics

Y-shaped fork design: The cable has a Y-shaped fork structure, with one end being a 16 pin male or female head of OBD2 (usually a female head to connect to the male head of diagnostic tools), and the other two ends being a 9 pin J1939 male head and a 6 pin J1708 male head respectively, which can simultaneously connect two different types of diagnostic ports on the vehicle.

Material and Quality: High quality PVC and PE materials are generally used for manufacturing, which have good flexibility, wear resistance, and corrosion resistance. They can adapt to the complex electrical environment and harsh usage conditions inside the vehicle, ensuring the stability and reliability of signal transmission.
