What to verify before choosing
Supplier labels for carbon or battery-health functions do not establish a direct carbon-deposit measurement or a calibrated battery load test. We do not claim those results. Report-service access and exact vehicle coverage still need confirmation.
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.
