ScanBuddy OBD2 Scanner

ScanBuddy is a simple OBD2 scanner. Plug a Bluetooth OBD2 adapter into the port under your dashboard, tap Scan Vehicle, and see what your vehicle has recorded, in plain words. WHAT IT SHOWS • Check engine light: on or off • Trouble codes, with a short meaning when one is known • Readiness monitors: see which are ready before an emissions test • Live data: speed, RPM, coolant temperature and more Tap the search button next to a code to look it up on the web. Your VIN is never part of the search. WHAT YOU NEED A Bluetooth Classic OBD2 adapter (ELM327 type), paired in your phone's Bluetooth settings first. Bluetooth Low Energy adapters (often sold "for iPhone") and Wi-Fi adapters will not connect. No adapter yet? Turn on Demo mode in More to try it. A scan only reads. Clearing codes is a separate step that asks first, and it also resets the readiness monitors. ScanBuddy is a scan tool, not a mechanic. Free. No account. No ads. In 26 languages.

ScanBuddy now comes in 26 languages. It follows your phone's language, or pick one in More. Trouble codes now sit at the end of a result, after the monitors and live data; you can move them back to the top in More. After a crash, safe mode now says your saved reports are protected, not gone.
