The OBDII port is typically located within a few feet of the steering wheel, often beneath the dashboard. Here are some of the most common locations:
- Under the dashboard, on the driver’s side: This is the most prevalent location, with the port often positioned near the steering column or above the pedals.
- Under the dashboard, on the passenger’s side: In some vehicles, the port might be located on the passenger side, mirroring the driver’s side placement.
- Inside the center console: Less common but still possible, the OBDII port can sometimes be found inside the center console, either beneath the armrest or on the front panel.
- Near the glove compartment: Occasionally, the port is placed near or inside the glove compartment, requiring you to open it for access.
