DTC P062F-46: Internal Control Module EEPROM Calibration / Parameter Memory Failure [11/2018 - 10/2023]: Description

The engine stop and start ECU stores the number of starter operations, total number of engine starts, air conditioning information, and the deceleration sensor zero point learning results.

If the engine stop and start ECU cannot write the number of starter operations, total number of engine starts, air conditioning information, or the deceleration sensor zero point learning results, it stores DTC P062F-46, blinks the stop and start cancel indicator, and prohibits stop and start control.
