You’re driving down the road, enjoying a scenic route, when suddenly your 2017 Toyota Highlander starts acting up. The engine light flashes, and you know something’s wrong. You pull over and try to figure out what’s going on, but you’re stuck. You need to get to a mechanic, but you don’t know where to start.
The first step is to find the OBD port, which is the gateway to your car’s diagnostic system. This small connector, usually located under the dashboard, allows you to communicate with your car’s computer and get valuable information about its health. But where is the OBD port on your 2017 Toyota Highlander? Let’s dive in!

What is the OBD Port?
The OBD (On-Board Diagnostics) port is a standardized connector found on most cars built after 1996. This port serves as a communication bridge between your car’s computer and external diagnostic tools. Mechanics use OBD scanners to read diagnostic codes that tell them exactly what’s wrong with your car.
