CAT 14-pin to 16-pin OBD2 Adapter Cable – Commercial and Work Vehicle
The CAT 14-pin to 16-pin OBD2 adapter cable is a specialized diagnostic adapter designed to connect modern truck scanners to Caterpillar machines and engines with a round 14-pin diagnostic connector. This connector is physically and electrically incompatible with standard 16-pin (J1962) or 9-pin (J1939) connectors.
This adapter forms a physical bridge between CAT-specific hardware and universal diagnostic equipment. This allows technicians to access essential vehicle information and electronic diagnostic functionality using common tools such as a CAT Comm Adapter, Nexiq Link, or other truck interface.
Application and functionality:
The cable enables deep communication with the ECUs and systems of Caterpillar machines. In combination with compatible software, users can:
- Read and clear fault codes: For EMS, transmission, and work hydraulics
- Monitor live data: View sensor data, pressures, RPM, operating temperatures
- Perform active tests: Start component tests or system diagnostics
- Configure parameters: (Depending on software) change operational settings
Supports communication protocols such as CAT Data Link (CDL) and J1939, depending on the equipment used and machine generation.
Compatible with the following vehicle makes and models:
This adapter cable is intended for Caterpillar equipment with a 14-pin diagnostic connector. Compatible with, among others:
- CAT Earthmoving machines: Excavators, bulldozers, graders, wheel loaders
- Industrial engines: Generators, marine applications, pump systems
- Trucks: Trucks with CAT engine (e.g. older Freightliner, Kenworth, Peterbilt)
Always check the diagnostic connector on site before purchase – CAT uses multiple types of connectors.
