What Is an OBD2 Scanner?

An OBD2 (On-Board Diagnostics II) scanner reads information from your vehicle's onboard computer. It identifies issues, clears trouble codes, resets warning lights, and helps with emission testing readiness.

One of our team members recalls using an OBD2 scanner during a long road trip. After a "Check Engine" light came on in a remote town, the scanner identified a minor sensor issue. Instead of waiting days for a mechanic, a quick reset and basic checkup got them safely back on the road — highlighting the vital role these tools play in modern vehicle ownership.

If your vehicle was manufactured after 1996, it’s OBD2 compliant and can work with these scanners.

2. Basic Code Reader vs. Full-System Diagnostic Tool
