Hi Herbie,
Much appreciated, I found a link and download for a small fee £10.00 before finding this website and very gratefull for the above link ..... covers Airsuspension spec which I needed as I no longer have access to LEXUS/TOYOTA, I worked for them 13+years and left as a Diagnostic technician, been off spanners now for about 6yrs .... so if you find yourself in Prestatyn area for any reason ..... and a lights on ... I have Techstream , long time since I lasted used the programme, just blowing dust off to correct some suspension issues as the garage wont track until corrected, I didn't even know it was out .... cheers herbie, thank you
