Compatibility disclosure

Generic OBD2 / EOBD engine and emission diagnostics on 12 V cars and light trucks with the 16-pin connector (KONNWEI states: American cars after 1999, European cars after 2002, Japanese and Korean cars after 2007, Chinese cars after 2009). The car must be OBD2 / EOBD compliant – check the "Vehicle Emission Control Information" sticker under the hood for "OBD II Certified"; cars with the private Japanese JOBD protocol (e.g. some Nissan units) are not supported. KONNWEI states it does not work with SsangYong, Lada / VAZ / UAZ, Opel Corsa C 2004 1.3 CDTI, Citroën C4 and C5, Renault Logan and Megane. The KONNWEI manuals give only "all 1996 and newer vehicles sold in the USA". Engine system only – no ABS, SRS, transmission, body or service functions.
