I recently purchased a Autel TS501 scanner to reprogram my 2004 Lexus SC430, but the vehicle software vehicle coverage only lists 2007-2011 cars. I then I did some home work that I need TS501US_Sys. Software V2.60 and MX Sensor V5.03 which can support my car. This V2.60 software can not be found at Autel online TPMS updates. Anyone can help me? Thanks
