I have tried all that but still no joy in getting it started the ABS light and engine management lights are on the stereo dont work and when I release the electric hand brake the light is still on, the start button stays orange and wont change to green has anyone got any info on how to get this car working without me taking it to the dealers

I have a 2007 Lexus IS250 with the auto-switchtronic gearbox. I have been driving the car perfectly fine until yesterday I started it up to go out but switch it off ran back inside to do something, 30mins later tried starting the car up again and it wouldn't start now I cant even put it into gear, the AA came out and there diagnosis machine cant even get a reading from the car as it refuses to communicate with there computer, has anyone got an idea's what could have caused the car to do that.
