how do you get to the Diagnostic Menu on an 08 GS

 

you can't, only from the diagnostic computer at dealers

*edit, you can...

 

Have you tried Display menu screen? Touch top left corner, bottom left corner and repeat this few times? Not sure about 08, on 07 this works.

yes it does work on 08

 

^^ Well I can confirm that this *does* work on my '08 GS350 - must be a GS460 thing Only thing I can't figure out is how to exit this screen, short of turning off the ignition. You can also get into the Nav menu and see how many birds in the sky you're tracking and also the exact GMT. . .

 

i also tested last night, the diagnostic menu is available

socal, to exit, press and hold DISP

 

Got it ! Thanks Henry (the guru of all things Lexus)

 

Is it possible to obtain the Diagnostic menu screen if the car doesn't have nav?

Thanks.

 

lol, and all i do is read that trick from someone else

 

guys I failed...

i did the up and down testing like 6 times then it went into the diagnostic

 

haha kev, you tried the info i gave you in pm?

how about the other car? tried it on that one too?

 

lol yea.. totally, and i did it on the way to work and I couldn't exit that stupid thing!

so I drove 20+ miles to work, without music.. without anything!

listen to the tiny rattles on the car wasn't pleasant at all..

I hate this diagnostic thing, I might've been confused with the NAV Override menu on the 06 GS

 

me too. that was a diagnostic menu of sorts but had the override feature. this one doesnt.

 

haha at least now you know how to exit it

 

Another newbie question. What can one do with this screen?
