My 2018 MXR says "Vehicle type unknown"

[wwmotors]

Hello guys, need some help: my 2018 MXR says on start up "vehicle type unknown". Zero mileage. Battery shows emtpy, but was full yesterday. Yesterday i had a "battery vcell timeout". May be it cannot read the firmware with the timeout problem? I have MT here. Is it battery or controller problem?Can someone provide some help?
If it helps, i have also a 2018 EXR here, to swap parts for testing, if necessary.

Hi. Maybe it's something to do with the 9v battery that might need replacing?, maybe...
Hope you get it all going again!.

Hello #76, today i completed the MXR and she is running again. Thats the good news. The bad news is, that i do not know why! I disasembled every ECU, every connector, DCCP, ACM, let it dry for 2 days, if there is humidity inside. Now she is starting and running like usual. I did not use MT. The 9 V Block was already new! Lets see what happens the next riding sessions!
