Product Functions & Connector Introduction
- Left red connector: Standard 16-pin OBD-II male plug
It is the vehicle-side connector to plug into the factory OBD diagnostic socket under the vehicle dashboard. It supports ECU fault code reading, real-time data stream acquisition, vehicle electronic module inspection and parameter calibration. The reinforced red housing improves durability against frequent plugging and unplugging in busy auto repair workshops.
- Right connector: DB15 (15-pin D-Sub) female socket
It connects to the main unit of professional diagnostic scanners such as Caterpillar ET4, and transmits driving data and fault signals collected from the vehicle OBD port to the diagnostic device for signal exchange and analysis.
Cable Features
- Multi-core shielded wiring effectively reduces electromagnetic interference generated in repair shops and engine bays, ensuring stable diagnostic data transmission without signal loss or reading failure;
- Strain relief design at both connector ends prevents cable breakage caused by frequent bending and pulling. The attached hook-and-loop strap allows easy cable bundling for storage and reduces outer sheath abrasion;
- Reinforced pins inside the OBD connector minimize pin deformation and poor contact issues after long-term repeated plugging;
- The cable outer jacket features great resistance to abrasion and oil contamination, adapting to dusty, greasy working conditions in repair garages.

Application & Usage Scenarios
- Maintenance diagnosis for passenger vehicles: Read & clear fault codes for sedans and SUVs, monitor live data of engine and transmission systems, and conduct basic inspection for electronic control modules;
- Inspection for light-duty diesel commercial vehicles: Perform engine trouble diagnosis and OBD emission data check for light trucks and box vans equipped with standard OBD ports;
- Function expansion for construction machinery diagnostic tools: When used with Caterpillar ET4 scanner and matched with CAT 14-pin / J1939 9-pin adapter cables, the tool can diagnose construction equipment like excavators and loaders, as well as ordinary civilian vehicles to diversify your maintenance service coverage.
Compatibility Note
This cable shall work with professional diagnostic scanners equipped with DB15 interface, mainly compatible with Caterpillar ET4 construction machinery diagnostic computer. As the core main cable of the whole wiring system, it works with CAT 14-pin and J1939 9-pin adapters to realize one-stop diagnosis for both construction machinery and civilian automobiles.
