What is an OBD2 Port and Why Is It Important?
OBD2 stands for On-Board Diagnostics, generation two. This standardized system allows you to connect a scan tool (also known as a code reader) to your car’s computer system to retrieve diagnostic trouble codes (DTCs), monitor real-time data, and access information about your vehicle’s performance.
Having access to this information can be extremely valuable for:
- DIY Repairs: Identifying the cause of a check engine light before taking your car to a mechanic.
- Maintenance: Monitoring your car’s engine performance and catching potential issues early.
- Customization: Some OBD2 scanners allow for modifications to certain vehicle settings.
