DESCRIPTION
The power management control ECU receives information from 2 sources. It receives information via a direct line and via the CAN communication line. If the information from these 2 sources is inconsistent, this DTC is stored.
HINT:
When the power management control ECU is replaced with a new one and the cable is connected to the negative (-) battery terminal, the power source mode is reset to on (IG). When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.
