Abyone here know how to get into the diagnostic/service menu in a GS430 ? I have instructions for a 99 gs but am not sure ig that will work on mine. Anyone know if that will work? or are they different. This is what I have:

**Disclaimer: This is from Banana GS's website "http://lexusmodz.netfirms.com/"

This is how you enable diagnostic mode, just turn off the car to get out of this mode
-Start car, turn on parking light
-Hold down both Climate and Audio buttons at the sametime do the next step
-Turn OFF parking light, then ON, then OFF, then ON, then OFF

This will put your in the SECRET/Service NAV menu

Thanks

 

no one in here knows how to???

 

ok this is kinda hard to believe that NO one here knows.... common guys.... share.. please?

 

did you try techinfo.toyota.com? pay like $10 a day or something and you can check all the tech docs... it's gotta be on there.

good luck
