Are you looking to diagnose a check engine light or perform routine maintenance on your Acura vehicle? Locating the OBD2 port is the first step. This guide will clearly explain where to find the OBD-II port in your Acura, ensuring you can quickly connect a scan tool and get the information you need. Whether you drive an Acura RDX or another model, this guide will help you pinpoint the diagnostic port location.
Common Location for Acura OBD2 Ports: Under the Dashboard
In most modern Acura vehicles, including the Acura RDX, the OBD-II port is typically situated underneath the dashboard on the driver’s side. This standardized location makes it easily accessible for technicians and vehicle owners alike. You’ll usually find it in the vicinity of the steering column.
Let’s examine a specific example to illustrate this common placement.
OBD2 Port Location in Older Acura Models: Center Console
For some older Acura models, particularly those manufactured around the year 2000, the OBD-II port might be located in a less conventional spot: behind the coin tray in the center console. This placement was more common in models like the Acura TL, CL, and TLS of that era.
If you suspect your Acura might have the OBD2 port in the center console, look for a small, removable plastic piece that serves as a coin tray. Once you remove this tray, you should find the standard 16-pin OBD-II port behind it.
It’s worth noting that even in models with the center console location, Acura transitioned to the under-dashboard placement around 2003. Furthermore, if coins or debris fall behind the coin tray, they can potentially obstruct access to the OBD-II port. Ensure there are no obstructions if you encounter difficulty connecting your scan tool.
Why is Accessing Your Acura OBD2 Port Important?
Knowing the location of your Acura’s OBD-II port is crucial for several reasons beyond just diagnosing a check engine light. This port is your gateway to your vehicle’s onboard computer system and is essential for:
- Diagnosing Warning Lights: Whether it’s the check engine light, ABS light, or airbag warning, the OBD2 port allows you to connect a scan tool to read fault codes and understand the issue.
- Performing Emission Tests and State Inspections: Many regions require vehicles to pass emission tests, which often involve accessing the OBD-II port to check system readiness.
- Using Diagnostic Scanners: From basic code readers to advanced multi-system scanners like the YOUCANIC Full System Scanner, the OBD2 port is the universal connection point for automotive diagnostics.

While a simple engine code reader can address basic engine light issues, diagnosing problems within systems like ABS or airbags typically requires a more comprehensive Multi-System OBD-II Scanner.
