The HV control ECU performs many diagnostic tests to verify proper operation of internal ECU systems. In one of these diagnostics, the HV control ECU performs a self-test. If the HV control ECU detects an internal problem during this self-test, it will conclude that there is an internal malfunction. The HV control ECU will illuminate the MIL and set a DTC.
