P2532-772 - Ignition Switch Run Position Circuit High

DESCRIPTION

The power source and HV CPU processors and their functions are integrated into the power management control ECU (HV CPU). The power source CPU and HV CPU use CAN communication to communicate with each other inside the power management control ECU. The power source CPU controls the opening and closing of the IG2 relay. The HV CPU detects that the IG2 relay is stuck ON (closed) based on relay operation information received from the power source CPU via CAN communication.
