Important Compatibility Notice
The supplied photo shows a round 9-position connector and a 16-pin OBD2-style connector. Connector appearance alone does not guarantee electrical or protocol compatibility. J1939 vehicles and diagnostic interfaces can use different connector generations, keying, pin assignments and communication standards. Verify the vehicle connector, diagnostic-tool requirements, pinout and protocol before ordering or connecting.
This is an adapter cable and does not itself add diagnostic, coding or programming functions to a scan tool.
