How to clear Permanent P0A80 Code?

Two things - is inspection mode the same as maintenance mode?
If it is, do you drive the whole universal trip while in maintenance mode, or do you shut the car off and start it again to leave maintenance mode?
I ask because I have seen warnings that you can destroy your inverter by driving in maintenence mode, it should only be used to idle. But on the other hand, the instructions nowhere say to leave maintenence mode before doing the universal trip - or even to stop the car, which seems to be the only way out of maintenance mods. Don't want to risk damage here. What have others done?
