If you depress the milage reset button for about 30 seconds, which activates onboard diagnostics on the spedometer display, you can scroll thru all onboard diagnostics using the upper button on the display select... Does any one know how this works... I came across it by accident just playing around and cannot find any information about this feature in my manual.. Thanks

I cannot change anything or access the topics that show up... What button do I push?
