## 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.
