What to look for in an OBD2 Scanner
An OBD2 scanner reads and clears check-engine codes, logs live engine data, and does basic diagnostics: saving repair-shop trips for simple issues.
Quick checklist
- Protocol support: make sure it supports your vehicle's protocols (CAN, ISO, KWP, J1850).
- App compatibility: check iOS vs Android support for the Bluetooth model you pick.
- Features: code read/clear is basic; live data, freeze frame, and bi-directional tests are advanced.
- Brand-specific: generic OBD2 scanners read emissions codes only; brand-specific codes may need a dealer tool.
