What to verify before choosing
The 35,901-entry fault-code library is a supplier claim, not a vehicle-coverage count. Cloud printing is documented, but the service and connection requirements still need checking. Reading voltage is different from a clamp-based battery test.
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.
