Experiencing a check engine light in your 1999 Toyota 4Runner can be concerning, and your first step towards diagnosing the issue yourself is locating the OBD2 port. For those new to modern vehicle diagnostics, or accustomed to older systems, finding this port can sometimes be a small challenge. This guide will quickly direct you to the location of the OBD2 port in your 1999 4Runner, enabling you to connect a scanner and retrieve those valuable diagnostic trouble codes.
Locating the OBD2 Port in a 1999 4Runner
Unlike some older vehicles, the 1999 Toyota 4Runner is equipped with a standardized OBD2 (On-Board Diagnostics II) port. You won’t need any tools to access it, and it’s situated in the driver’s cabin for easy access.
To find the OBD2 port in your 1999 4Runner, position yourself in the driver’s seat. Reach down and to the right of the steering column, towards the center console and gas pedal area. The OBD2 port is located underneath the dashboard in this region. You’ll be looking for a black, trapezoid-shaped connector, which is designed to be easily accessible without requiring any tools.
Sometimes, the darkness under the dash can make it slightly difficult to spot immediately. It’s helpful to use a flashlight or the light from your smartphone to illuminate the area. The port is designed to protrude slightly, making it identifiable once you are looking in the correct general location.
