What is an OBD2 Port and Why is it Important?

The OBD2 port, short for On-Board Diagnostics, is a standardized 16-pin connector found in vehicles manufactured after 1996. It allows mechanics and vehicle owners to access the truck’s onboard computer and retrieve valuable diagnostic information.

This information includes:

Diagnostic trouble codes (DTCs)
Engine performance data
Emission-related data
Sensor readings
Vehicle speed and mileage

Accessing this data helps diagnose engine problems, track performance, analyze fuel efficiency, and ensure the vehicle runs smoothly.

In most International Durastar 4300 trucks, the OBD2 port is located under the dashboard, on the driver’s side, either beneath the steering column or near the fuse panel. The exact location may vary slightly depending on the model year and trim level.

Here’s a step-by-step guide to help you find it:

Park your truck on a level surface and engage the parking brake.
