Description
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.
Condition
The vehicle detects at least one ECU required to supplement HV battery heating with waste heat running a different firmware version than expected.
Clear Condition
The vehicle no longer detects any ECU required to supplement HV battery heating with waste heat running a different firmware version than expected.
Potential Impact
Inability to use waste heat to supplement HV battery heating may make charging at colder temperatures limited or unavailable.
