I've just started using my MPVI3 and I completed the training courses, so that opened up the Parameter Access for me. However, even though I can now see additional parameters and maps on one of my other vehicles, my Nissan Titan is still missing the OS, Fuel Sys, System, and Speedo windows. They don't show anything, just blank windows. I'm trying to edit the fuel tank/gauge map to correct the gauge (which shows 1/3 of a tank when it is empty), but I seem to have no access to the map. I have to connect to the vehicle on this one to run the VCM Editor, otherwise it will give a definitions error.

Am I missing something, or is there additional training or requirements for this? Is this normal for the Titan? Thx.
