Here are a few of the error code briefs; these may not help you fix the issue, but at least you have a bit more information about possible issues!
2011 - Motor actuation too high
800F - Unstable power
8003 - Fault between battery and controller
8010 - Controller communication error
8012 - No battery connection
Note - Codes such as 8012 might only by for a tenth of a second; for example a bump has caused the battery to "jump" off the connector.
