1. Understanding the OBD2 Port

The On-Board Diagnostics II (OBD2) port is a standardized interface used to access the vehicle’s computer for diagnostics and monitoring. According to the Environmental Protection Agency (EPA), all cars and light trucks manufactured after 1996 in the United States are required to have an OBD2 port. This standardization ensures that any compatible scan tool can retrieve diagnostic trouble codes (DTCs) and other essential data from the vehicle’s computer. The OBD2 system monitors various parameters, including engine performance, emissions, and transmission behavior.

What is OBD2?
