VCLEFT_a340_HVBlckdByMsmtch
Description
The vehicle has detected at least one electronic control unit (ECU) required for high voltage (HV) system operation 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 HV battery contactors from closing and HV system from becoming active to make sure no ECU required for HV system operation 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 for HV system operation running a different firmware version than expected.
Clear Condition
The vehicle no longer detects any ECU required for HV system operation running a different firmware version than expected.
Potential Impact
