This typically includes pre-OBD2 era models manufactured before the late 1990s\/early 2000s. If your vehicle has a 3-pin diagnostic port, this cable should allow you to connect a standard 16-pin OBD2 scan tool or diagnostic interface.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this cable work as a standalone diagnostic tool?\u003c\/h4\u003e\n\u003cp\u003eA: No — this is purely a passive adapter cable. You will still need a compatible 16-pin OBD2 diagnostic scanner or interface (sold separately). This cable simply converts your vehicle's 3-pin port to the standard 16-pin OBD2 format so your scan tool can connect properly.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this OBD2 adapter cable safe to use in my vehicle?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This adapter cable holds CE certification, confirming it meets European safety and quality standards. It contains no hazardous chemicals and requires no batteries or external power — just plug it in between your vehicle's 3-pin port and your OBD2 scan tool.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is included in the package?\u003c\/h4\u003e\n\u003cp\u003eA: The package includes 1 × 3-Pin to 16-Pin OBD2 diagnostic adapter cable.
