The On-Board Diagnostics II (OBD2) port in your 2019 Subaru Forester is a crucial access point for vehicle health information. Whether you’re a seasoned DIYer or a car owner wanting to understand your vehicle better, knowing the OBD2 port location is the first step towards effective car diagnostics and maintenance. This port allows mechanics and car owners to connect scan tools to read diagnostic trouble codes, monitor live data, and ensure your Subaru Forester is running smoothly.

Locating the OBD2 Port in Your 2019 Subaru Forester
For the 2019 Subaru Forester, the OBD2 port is typically located within the cabin area, making it easily accessible from the driver’s seat. You won’t need any tools to access it. Specifically, you should look for the OBD2 port under the dashboard on the driver’s side.
It is generally positioned near the steering column, often in the area where the driver’s side door panel meets the dashboard when the door is closed. You might need to crouch down slightly and look upwards under the dash to spot it. The OBD2 port is a 16-pin, trapezoid-shaped connector, distinct from other connectors in your vehicle.

Troubleshooting OBD2 Port Connection Issues
Once you’ve located the OBD2 port, you might encounter issues when trying to connect a scan tool. If your scan tool fails to connect or power on when plugged into the OBD2 port, here are a few common problems and troubleshooting steps:
-
Check for Loose or Corroded Connections: Examine the OBD2 port for any visible damage or corrosion. Ensure the scan tool connector is fully and firmly plugged into the port. Sometimes, loose connections or corrosion can prevent proper communication.
-
Faulty OBD2 Port: Although less common, the OBD2 port itself can be faulty. Physical damage or internal wiring issues within the port might require professional inspection and potential replacement.
-
Inspect the Fuse: A blown fuse is a frequent culprit for a non-functional OBD2 port. Locate the fuse box diagram for your 2019 Subaru Forester (usually in the owner’s manual or on the fuse box cover). Identify the fuse associated with the OBD2 port or accessory power and check if it’s blown. Replace it with a fuse of the same rating if necessary.
-
Onboard Computer Problems: In rare cases, issues with your Subaru’s onboard computer (ECU/PCM) can affect OBD2 port functionality. If other troubleshooting steps fail, this might indicate a more complex problem requiring professional diagnosis.
-
Battery and Power Supply: A weak or undercharged car battery can sometimes cause the OBD2 port to malfunction. Ensure your car battery is in good condition and properly charged.
If you’ve checked these common issues and are still experiencing problems, it’s advisable to seek assistance from a qualified mechanic to diagnose the root cause accurately.
Selecting the Right Scan Tool for Your Subaru Forester
For diagnosing your 2019 Subaru Forester, various scan tools are available, ranging from basic code readers to advanced professional-grade scanners.
