Monitor Description

The power management control ECU (HV CPU) monitors signals of HV battery voltage (VB) and boost converter voltage (VL) sensors. When a large difference occurs between the voltages from the VB and VL sensors, the power management control ECU (HV CPU) interprets this as a failure of either of the sensors. The power management control ECU (HV CPU) will illuminate the MIL and set a DTC.
