Re: Lexus GS450h tpms

Yeah hello Ian thanks for the reply. The techstream is a moody one but have used it before on something similar without any issues.The live data doesnt show an instant change to tyre pressure changes but does eventually catch up. The codes are being written to the ecm as I have tried changing them around and this does follow. The codes were obtained by manually removing tyres as they needed replacing thru wear.One thing I did find today was that a replacement sensor I installed (Schraeder) is not giving live data ie pressure or temperature.Ive tried reading all sensors with an Autel TS401 which incidentally states that the frequency should be 315mhz and im pretty sure the one I purchased through a reputable TPMS supplier was 430MHZ this obviously wont help matters and I will need to break the bead to double check. What I dont understand is why the sensors cannot be read by the Autel by choosing both types of frequency?Is there some means of waking these up?
