Monitor Description
The power management control ECU (HV CPU) performs diagnostic tests to verify proper operation of internal ECU systems. One of these monitors the rationality of internal analog (signal) to digital conversions. The power management control ECU (CPU) monitors the internal A/D (Analog/Digital converter) value. If there is an A/D converter malfunction, the power management control ECU (HV CPU) will illuminate the MIL and set a DTC.
