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.

DTC No.

Voltage is still applied to IG2 terminal although an IG2 relay off command is received from the power source CPU.
  1. Wire harness or connector
  2. No. 2 integration relay (IG2 relay)
  3. Power management control ECU
