DESCRIPTION

The hybrid vehicle control ECU monitors its internal operation, and it will set DTCs and perform fail-safe control when it detects malfunctions. If any of the following DTCs are output, replace the hybrid vehicle control ECU.





MONITOR DESCRIPTION

The hybrid vehicle control ECU 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 hybrid vehicle control ECU monitors the internal A/D (Analog/Digital converter) value. If there is an A/D converter malfunction, the hybrid vehicle control ECU will illuminate the MIL and set a DTC.
