Description
LAUNCH • X431 Creader CR319 OBD2 reader
This LAUNCH CR319 OBD2 reader is a compact code scanner designed for car owners and DIY mechanics to diagnose engine issues with minimal effort. The instrument supports all standard OBDII/EOBD protocols—SAE J1850 PWM, J1850 VPW, ISO9141-2, ISO14230-4 (KWP), and ISO15765-4 CAN—to communicate with the engine control unit and read diagnostic trouble codes. Plug-and-play operation means it powers via the vehicle’s OBDII port and begins working immediately. Features include real-time data streaming, freeze frame capture, emission readiness tests, and a built-in code lookup library. The device is compatible with most 12-volt gasoline and diesel vehicles manufactured since 1996 in the US, 2003 in Europe, 2006–2009 in Asia, depending on the region. CR319 is not intended for hybrid, electric, 24-volt heavy duty, or 12-volt diesel in some cases.
