Service bulletin TSB230193
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
This Technical Service Bulletin describes the verification and recalibration steps for the system control module calibration which may falsely detect low or high voltage on the isometer low voltage supply circuit, resulting in false-positive fault codes and a stop EV lamp becoming active during charging. This is an update to a previously submitted communication.
