Hi.
Last Year i was searching in Engineering mode on my command system and a found pulse count menu for the wheels. It was showing rotation for all four wheels and this was used by navigation in case of gps signal lost (lets say undeground, tunnels etc.). This summer i found that this menu is not showing rotation any more... What can be a problem? does anybody know this?

 

I will make photo of menu and how to get there later on today. Probably not everybody have this function.
