What to verify before choosing
The screen size does not establish wider system access. Do not assume support for ABS, airbags or service resets. The listed EVAP and oxygen-sensor functions require support from the vehicle.
Designed for supported OBD-II / EOBD vehicles. Available data and functions depend on the vehicle, model year and diagnostic protocol. Engine OBD support does not imply ABS, SRS, transmission or service-function coverage.
