Monitor Description

The HV control ECU performs diagnostic monitoring to verify proper operation of internal and external ECU systems. In one of these monitors, the HV control ECU monitors the power supply for the motor main CPU.

If the HV control ECU detects a failure in the power supply for the motor main CPU, it will illuminate the MIL and set a DTC.
