What to know before buying

Compatibility is claimed for most US, Asian and European OBD2 vehicles from 1996 onward, with stated coverage through 2023 and active work on 2024 coverage. The listing also says use is limited to the United States and Canada. FCA vehicles from 2018 onward require AutoAuth access, which the listing says is not supported. Verify the exact vehicle and functions with Innova's coverage checker. Clearing codes or disconnecting the battery resets readiness monitors, which need a complete drive cycle to repopulate.

Less suited to

Owners who need guaranteed ABS or oil-reset support without checking their specific vehicle.
FCA vehicle owners with 2018-or-newer models who require AutoAuth-dependent functions.
Buyers seeking a wireless scanner, since the listing describes a vehicle-powered reader with an attached OBD2 cable.
