Hello All,

I'm troubleshooting an issue with my 2011 Zero DS.  I've been having erratic issues with the bike having all power drop while riding around  Motor goes dead, and dashboard goes blank.

I looked through the log on the bike via the diagnostic interface (looks like event 457 is where I had the bike drop power):

Code: [Select]

Is there anything that can trigger a software restart?

As a side note, it seems that I have a bunch of CANBUS errors throughout the log where it says CANBUS Connection Error, and CANBUS connection restored with the same timestamp, and occasionally when I connect via the diagnostic connector the bike the mbb crashes (quits responding in terminal) and the fuel gauge on the dash goes blank.

I don't know what events might trigger a software reset on an MBB, apart from resetting it by hand via the terminal.

The canbus errors might trigger a software reset. The only canbus connection is going to the battery, via the multipin connector. I would check that connector first.
