Chris, Wayne, you can help by testing switching off the SN65: https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/980#... As Richard wrote, he could not reproduce the issue in his Leaf by that, but on his bench. If that's the culprit, there still is the Housekeeping SN65 switch-off to address, but there is probably little we can do about cold boots. Regarding floating voltages, see Richards followup post. Also I suggest asking Richard how you can help in narrowing this down. Regards, Michael Am 11.04.25 um 23:18 schrieb Wayne Love via OvmsDev:
Rather than the crash, it could be the subsequent boot that causes the problem.
Previously I've caused the 2016 car to throw dashboard errors by typing "module reset" over SSH while charging was in progress. I assume this is an orderly shutdown, and hence it's the boot process that disturbs the CAN bus of an active car.
Chris My thinking is that the issue is caused when the module goes down. The reason that I say this is that in my instances when the module crashes it does not come back up again, you need to power cycle it for it to restart.
Is there a chance that we are seeing floating voltages on the CAN connectors when they are not actively controlled by the cpu?
