Frequently Asked Questions

Q: Is this OBD2 extension cable compatible with my vehicle?

A: This 16-pin OBD2 extension cable is designed to be universally compatible with all OBD2-compliant vehicles, which includes most cars and light trucks manufactured from 1996 onwards. As long as your vehicle has a standard 16-pin OBD2 port, this cable should work seamlessly.

Q: Does the power switch completely cut power to my OBD2 device?

A: Yes. The inline power switch on this cable allows you to fully cut power to any connected OBD2 device — such as a GPS tracker or plug-in dongle — without physically removing it from the port. This is ideal for preventing unnecessary battery drain when your vehicle is parked for extended periods.

Q: Can I use this cable as a splitter to run two OBD2 devices at once?

A: This cable is designed as an extension/splitter adapter, allowing you to extend the reach of your OBD2 port or pass through the connection to multiple compatible devices. Please verify your specific devices' compatibility before use, as simultaneous multi-device use may vary depending on the tools connected.

Q: Is a diagnostic scanner included with this cable?

A: No — this product is the OBD2 extension cable adapter only. A separate OBD2 diagnostic scanner is required to perform vehicle diagnostics. This cable simply extends and adds switch control to your existing OBD2 connection.
