You’re planning to work on your Lexus ES 350, and you need to find the OBD2 port. It’s a common question, especially if you’re working on a repair or a customization project. Finding the OBD2 port might seem like a simple task, but it can quickly become a frustrating puzzle, especially if you’re unfamiliar with your vehicle’s layout. Let’s break down the process of locating the OBD2 port in your Lexus ES 350, along with common issues and helpful tips.
Understanding the OBD2 Port
What is the OBD2 Port?
The OBD2 (On-Board Diagnostics II) port is a standardized connector found on most vehicles manufactured after 1996. It’s a gateway for communicating with the vehicle’s electronic control units (ECUs). These ECUs manage various systems like the engine, transmission, ABS, and more.
Why is the OBD2 Port Important?
This port plays a vital role in vehicle maintenance and troubleshooting. It allows:
- Diagnostic Scanning: Using a diagnostic scanner (like a dealer scanner for European cars), you can access real-time data and fault codes stored in the ECUs.
- Data Logging: Gather data on various vehicle parameters for analysis and troubleshooting.
- Programming and Re-flashing ECUs: Update software and parameters to address specific issues or enhance vehicle performance.
Locating the OBD2 Port in your Lexus ES 350

Using the Owner’s Manual
Refer to your Lexus ES 350 owner’s manual for the precise location. This will save you time and effort. The manual will often include illustrations to guide you directly to the OBD2 port.
