The vehicle has detected at least one electronic control unit (ECU) required to supplement high voltage (HV) battery heating with waste heat running a firmware (software) version that may not be compatible with the firmware installed on the rest of the vehicle. When this occurs, the vehicle controller blocks the supplemental HV battery heating to make sure no ECU required is limited or unavailable due to firmware. May occur after an unsuccessful or incomplete firmware update, and may be resolved through a successful firmware update.
