Monitor Description
If the difference between the requested boost converter voltage and the actual boost converter voltage exceeds a predetermined value, the MG ECU determines that there is a malfunction of the execution or monitoring in the boost converter voltage. The MG ECU will send information about the malfunction to the power management control ECU (HV CPU). Upon receiving this information, the power management control ECU (HV CPU) will illuminate the MIL and set a DTC.
