The On-Board Diagnostics II (OBD2) port in your 2017 Toyota Corolla is a crucial access point for vehicle diagnostics and maintenance. Whether you’re looking to read trouble codes triggered by your check engine light or monitor your car’s performance, knowing the location of this port is the first step. This guide will show you exactly where to find the OBD2 port in your 2017 Toyota Corolla and what it’s used for.
Understanding the OBD2 Port
Since 1996, OBD2 has been a standard in most vehicles, providing a universal interface for accessing your car’s computer system. This standardization means that any certified OBD2 scanner can communicate with your 2017 Toyota Corolla, allowing you to diagnose issues and maintain your vehicle effectively. The port is designed to be easily accessible, typically located within the passenger compartment.
Locating the OBD2 Port in a 2017 Toyota Corolla
For the 2017 Toyota Corolla, the OBD2 port is located in a readily accessible spot, making diagnostics straightforward. Follow these steps to find it:
-
Check Under the Dashboard: The most common location for the OBD2 port is beneath the dashboard on the driver’s side.
-
Look for the Knee Area: Specifically, you’ll want to look in the area around your knees when you are seated in the driver’s seat. The port is usually within easy reach from the seated position.
-
Inspect for a Trapezoid-Shaped Connector: The OBD2 port is a 16-pin, trapezoid-shaped female connector. It’s quite distinctive and should be easily recognizable.
-
It’s Usually Uncovered: In most 2017 Toyota Corollas, the OBD2 port is not covered by a protective flap or cover. It is designed for easy access. You should be able to see it directly without needing to remove any panels.

What Can You Do With the OBD2 Port?
Once you’ve located the OBD2 port in your 2017 Toyota Corolla, you can utilize it for a variety of diagnostic and monitoring tasks using an OBD2 scanner tool. Here are some common uses:
-
Reading Trouble Codes: When your check engine light illuminates, it signifies that your car’s computer has detected an issue. An OBD2 scanner can read these diagnostic trouble codes (DTCs), providing you with information about the potential problem.
-
Clearing Trouble Codes: After addressing the issue causing the check engine light, you can use an OBD2 scanner to clear the stored trouble codes and turn off the light. However, it’s crucial to fix the underlying problem first; otherwise, the light will likely reappear.
-
Real-Time Data Monitoring: OBD2 scanners can display live data from your vehicle’s sensors, such as engine speed (RPM), coolant temperature, oxygen sensor readings, and more. This real-time data is invaluable for understanding your car’s performance and diagnosing intermittent issues.
-
Emissions Testing: In many regions, emissions testing involves connecting to the OBD2 port to check for emissions-related trouble codes and system readiness.
Using an OBD2 Scanner
Using an OBD2 scanner with your 2017 Toyota Corolla is generally a straightforward process:
-
Turn Off the Ignition: Ensure your car’s ignition is turned off before plugging in the OBD2 scanner.
-
Locate the OBD2 Port: As described earlier, find the OBD2 port under the dashboard on the driver’s side.
-
Plug in the Scanner: Connect the OBD2 scanner to the port. It should plug in securely.
-
Turn the Ignition to “ON” (Engine Off): Turn your key to the “ON” position without starting the engine. This provides power to the car’s computer and the OBD2 port.
-
Follow Scanner Instructions: Power on your OBD2 scanner and follow the manufacturer’s instructions to read codes, view live data, or perform other diagnostic functions.
-
Turn Off Ignition and Disconnect: Once you’re finished, turn the ignition off and disconnect the OBD2 scanner.
