This is for my 2003 LS 430 UL with navigation.
Car in Park , appy parking brake, turn ignition swith to Acc, while pressing and holding the Option button on the multi display turn light control switch from ,off-tail-off-tail-off-tail-off . The sevice check mode will be displayed.
From this screen you can press menu in the top right and will take you back to the Diagnosis Menu, where access to the Service Check, Display Check, and Navigation Check , are available. To Exit the menus turn ignition switch off.

PLEASE TRY AT YOUR OWN RISK. DO NOT TRY ANY BUTTONS YOU ARE NOT SURE ABOUT....
