How to locate your Toyota OBD2 port

 
So, you've got your OBD diagnostic scanner in hand, and now you're wondering, “Where do I plug this thing in?” Or maybe you’re simply curious about your Toyota’s systems. Either way – we’ve got you covered. 
 
Whether you need to troubleshoot diagnostic trouble code, check cruise control operation, or test fuel pump, finding your Toyota's OBD2 (also called OBD-II) port is simple task once you know where to look. 
 
The OBD2 port is a standardized connector found in most vehicles since 1996, including Toyota. It lets a code reader communicate with the vehicle's onboard diagnostic system to access trouble codes, read live data from various sensors, and retrieve other important information.

How to find OBD2 port in my vehicle?

 
This OBD2 port is trapezoid-shaped, has 16 holes for sockets, and is usually black, white, or purple. In most vehicles, you’ll find this port in a few common places:
 
  • Under the dash, above the pedals: This is the most common spot where you’ll find Toyota OBD ports. 
  • Near the center console or below the multimedia: Some cars have the port closer to the middle of the car, usually beneath removable panels. 
  • Inside or near the glove box: In some vehicles, the port might be inside or next to the glove box.

Are all the OBD2 ports the same?

 
While all OBD2 diagnostic connectors may look similar, they're not the same. The OBD2 connector has 16 sockets, but only specific sockets are active depending on your vehicle's communication protocols. These protocols can vary by manufacturer, region, and model year.
 
Because of these differences, it is important to choose an OBD scanner that is compatible with your car. Although the connectors may look alike, the real differences lie in the hardware and software needed to properly read and interpret data from your vehicle's on-board diagnostic system. 
 
For example, in 2008, Toyota switched to the CAN bus communication protocol. This means all 2008 and newer Toyota vehicles are compatible with OBD2 scanners that support CAN bus, such as OBDeleven diagnostic tool
 
You can confirm if your car uses the CAN bus protocol by inspecting the OBD2 connector. If pins 6 and 14 are active, your car has the CAN bus.
