Is your battery still an original battery? If yes - I sense the battery may have to be replaced.

Code 213A21 is stored immediately if the voltage is less than 10 volts. Failing alternator is the usual suspect with DME being the second.

Suggestions:

- Replace the batter if still OEM; failing battery can trigger many codes to be stored
- Clear all codes and scan for new codes within 2 days
- Check wiring and all connectors to the alternator
- If the voltage is still low, indy shop can diagnose the alternator performance

+1 for checking battery and connections. A failing battery will wreak havoc on everything and can throw any code under the sun.
