1. Understanding Dacia OBD2 Compatibility

1.1. What is OBD2 and Why is it Important for Dacia Vehicles?

OBD2 (On-Board Diagnostics II) is a standardized system used in most vehicles to monitor and diagnose engine and emission-related issues. According to the Environmental Protection Agency (EPA), OBD2 was mandated in the United States for all cars and light trucks manufactured after 1996 to ensure emissions compliance. For Dacia vehicles, OBD2 compatibility allows owners and technicians to access valuable data about the car’s performance, identify potential problems, and perform necessary maintenance. Using an OBD2 scanner with your Dacia can help you:

• Read and clear diagnostic trouble codes (DTCs)
• Monitor real-time engine data
• Check emission readiness
• Perform basic system tests
