Support List

OBDAI provides extensive vehicle coverage, focusing primarily on the US market while supporting vehicles from major global regions based on their OBD2 adoption timelines. Our compatibility extends to European Union (EOBD) vehicles from 2001 onwards for gasoline engines and 2004+ for diesel engines, Japanese vehicles from 2002 onwards, and Australian vehicles from 2006+. Additional regions are supported based on their local OBD2 implementation dates, ensuring broad international coverage for our diagnostic capabilities.
