The Tesla Model Y, like the Model 3, doesn’t come equipped with a standard OBD2 port. This can make diagnostics and using certain accessories challenging. However, an OBD2 adapter provides a solution by allowing you to add an OBD2 port to your Tesla Model Y. This guide will walk you through locating the necessary connectors and installing the adapter.
Locating the OBD2 Adapter Connection Point in Your Tesla Model Y
The location of the connection point for the OBD2 adapter depends on the model year of your Tesla Model Y:
-
Model Year 2019-2023: The adapter connects to wiring harnesses located in the rear footwell, beneath the center console. You’ll find a small protective cover secured by five clips that you’ll need to remove to access these connectors.
-
Model Year 2024 and Newer: Tesla relocated the connection point to the driver’s side footwell, on the right side behind a panel. This change simplifies installation compared to previous models.
Installing the OBD2 Adapter in Your Tesla Model Y
Before starting the installation, it’s crucial to completely power down your Tesla Model Y. This ensures the safety of the vehicle’s electrical system and prevents potential damage. Follow these steps:
-
Disable Sentry Mode: Turn off Sentry Mode via the Tesla mobile app or the touchscreen (Controls -> Security -> Sentry Mode = Off).
-
Open Windows and Doors: Fully open the driver’s side window and close the driver’s door. Open a rear door for access after power off.
-
Initiate Power Off: On the touchscreen, navigate to Controls -> Security -> Power Off.
-
Wait for Complete Shutdown: Wait outside the vehicle for 8-10 minutes until you hear a relay “click” and all humming ceases. This confirms the car is fully powered down.
-
Access the Connectors:
- 2019-2023 Models: Carefully remove the protective cover in the rear footwell by gently pulling or prying the five clips.
- 2024+ Models: Remove the panel on the right side of the driver’s footwell.
-
Connect the Adapter: Disconnect the appropriate connector and place the OBD2 adapter between the two connector ends. Ensure a secure and proper connection.
-
Reassemble: Replace the cover or panel.
-
Route the OBD2 Port: For easier access, consider routing the OBD2 port cable under the casing in the rear footwell or beneath the front seats. This avoids repeatedly removing the cover for OBD2 device connection.

Using the OBD2 Port on Your Tesla Model Y
Once installed, the OBD2 adapter allows you to connect various devices to your Tesla Model Y, such as:
- OBD2 Scanners: Diagnose and troubleshoot vehicle issues.
- Bluetooth OBD2 Dongles: Monitor vehicle data in real-time using smartphone apps.
- Accessories: Connect accessories like auxiliary lights or data loggers.
By following this guide, you can successfully install an OBD2 adapter and unlock the diagnostic and accessory capabilities of your Tesla Model Y. Remember to always prioritize safety and ensure the vehicle is fully powered down before starting any installation work.
