The adapter cable converts the specific CAT 14-pin diagnostic connector to a standardized 16-pin OBD2 (J1962) port. This makes it possible to connect modern diagnostic equipment to various commercial and work vehicles from Caterpillar for performing diagnostic tasks and reading system data.

The cable is designed for compatibility with the communication protocols used by Caterpillar systems, such as J1939 and CAT Data Link (CDL). The construction is aimed at providing a stable connection in demanding work environments, such as construction sites or workshops.


Application and functionality:

This adapter cable is designed to establish a connection between a vehicle-specific diagnostic port and a universal reading device.

  • Diagnostic connection: Connects a 16-pin OBD2 diagnostic device to the 14-pin port of Caterpillar vehicles and machines.
  • Reading and programming: Enables reading and clearing fault codes (DTCs), viewing live data, and, depending on the software used, configuring components.
  • Protocol support: Facilitates communication via protocols such as J1939, common in heavy equipment.

Compatible vehicles and applications:

The adapter is suitable for a wide range of Caterpillar (CAT) machines, engines, and industrial equipment equipped with the 14-pin round diagnostic connector. Compatibility is not limited to specific models or years of manufacture but includes various product categories.

  • Construction machines: Excavators, wheel loaders, bulldozers, skid steer loaders, graders.
  • Industrial engines: Engines used in generators (gensets), pumps, and other stationary applications.
  • Trucks: Trucks equipped with a Caterpillar engine and the corresponding 14-pin connection.

Important: Before purchasing the product, always check your vehicle's connection. This may vary by model and year of manufacture.
