DESCRIPTION

The HV control ECU performs self-checks to detect an internal operating malfunction in the ECU.






MONITOR DESCRIPTION

The HV control ECU performs diagnostic monitoring to verify proper operation of internal and external ECU systems. In this diagnostics monitor, the HV control ECU monitors the output of the rotation angle CPU.
If the HV control ECU detects an error in the rotation angle CPU, it will conclude that there is an internal malfunction in the HV control ECU. The HV control ECU will illuminate the MIL and set a DTC.
