Nissan 14-Pin to OBD2 16-Pin Diagnostic Adapter Cable

Bridge the gap between older Nissan vehicles and modern OBD2 diagnostic tools with this reliable Nissan 14-Pin to OBD2 16-Pin adapter cable. Designed specifically for pre-1996 Nissan models equipped with a proprietary 14-pin diagnostic socket, this adapter converts your vehicle's connector to the universal OBD2 (16-pin) standard — letting you use today's scan tools to read fault codes, diagnose issues, and keep your Nissan running smoothly.

Made in Mainland China.

Frequently Asked Questions

Q: Which Nissan vehicles is this 14-pin to OBD2 adapter compatible with?

A: This adapter is designed for pre-1996 Nissan vehicles that use the proprietary Nissan 14-pin OBD1 diagnostic connector. This includes many older Nissan and Infiniti models manufactured before the industry-wide switch to the standardized OBD2 (16-pin) port. Always confirm your vehicle's diagnostic port type before purchasing.

Q: Do I need any special software to use this Nissan 14-pin to OBD2 adapter cable?

A: No — this is a purely passive wiring adapter that requires no software, drivers, or power of its own. Simply connect it between your vehicle's 14-pin socket and your OBD2 diagnostic scanner or pass-thru device (such as the Multi-Diag J2534). Your scan tool's software handles all the diagnostics.

Q: Will this adapter work with any OBD2 scanner?

A: This adapter provides the physical connection between Nissan's 14-pin port and a standard OBD2 16-pin connector. However, your OBD2 scan tool must also support Nissan OBD1 protocols (pre-1996 vehicles) in its software. Not all generic OBD2 readers include legacy OBD1 protocol support — check your scanner's compatibility list before use.

Q: Is this adapter the same as a standard OBD2 extension cable?

A: No. This is a protocol conversion adapter specifically designed for Nissan's unique 14-pin OBD1 diagnostic port. A standard OBD2 extension cable uses 16 pins on both ends and will not fit Nissan's older 14-pin socket. This adapter bridges the two different connector standards.
