OBD2 Adapter Cable Tesla 2012–2015 (Model S/Model X) – 12-pin female to 16-pin OBD2, for external diagnostics/OBD2 tools
Short Version
This cable is a practical OBD2 adapter/extension for older Tesla models where the connection is not a standard 16-pin OBD2 connector. It is specified as a 12-pin female OBD2 connector to 16-pin OBD2 and is intended for Tesla Model S and Model X model years 2012–2015.
The purpose is simple: the cable replaces/adapts the car's OBD interface so you can connect external diagnostic tools that use standard 16-pin OBD2. The product is explicitly described as being “without functions” – meaning it contains no electronics, does not encode/translate protocols, and does not “unlock” extra features. It functions as a physical connecting cable to provide the correct connector format when you want to plug in an OBD2 tool.
Perfect if you already have an OBD2 device (scanner, logger, or other diagnostic equipment) and need a simple, passive cable to connect it to a 2012–2015 Tesla with a 12-pin socket.

What is this cable?
It is an adapter cable that converts a 12-pin connection (female) to a standard 16-pin OBD2 connector. It is used when the car does not have a regular 16-pin OBD2 port, but you want to connect a common OBD2 diagnostic tool.
Compatibility (according to product text)
-
Tesla Model S: 2012–2015
-
Tesla Model X: 2012–2015
Note: Always verify that your car actually has the 12-pin connection that matches this cable before purchase/installation.
Usage: connecting external diagnostic tools
- Turn off the car and locate the car's diagnostic/OBD interface (12-pin).
- Connect the cable's 12-pin female to the car's connector.
- Then connect your 16-pin OBD2 tool to the cable's OBD2 end.
- Start/activate your diagnostic tool and follow the instructions in the tool/app.
The cable is intended to enable connection – what data and functions you can read depends on your equipment and the car's support.
Important to know: “cable without functions”
The product description states that the cable is “without Functions”. This means that:
- it contains no electronics (passive cable)
- it does not translate protocols and does not add support for new systems
- it is a connector adapter for plugging in external tools

FAQ – Frequently Asked Questions
1) Is this a real OBD2 scanner?
No, this is an adapter cable. You need a separate diagnostic tool/OBD2 scanner to read data.
2) Does the cable give me more features in the car?
No, it is explicitly "without functions" and contains no electronics. It merely allows you to connect a 16-pin OBD2 tool.
3) Does it fit all Tesla Model S/X?
It is specified for Model S/Model X 2012–2015. Check the connector and model year before purchase.
4) Does it work with all OBD2 apps and dongles?
The cable provides a 16-pin OBD2 connector, but whether your dongle/app can actually communicate depends on the car's system and what your equipment supports.
5) Is it safe to use?
It is a passive cable, but always work carefully around vehicle connectors and avoid plugging/unplugging if you are unsure where the socket is located.
Notices & Safety
- Verify that your Tesla (2012–2015) has the correct 12-pin connector that matches the cable.
- This is a passive adapter – it does not replace a diagnostic tool.
- What data you can read depends on your diagnostic tool and the car's support.
