DESCRIPTION

The HV control ECU monitors internal operations and detects a malfunction.






MONITOR DESCRIPTION

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 checks the result of the engine CPU self-test. If the HV control ECU detects a "Fail" from the engine CPU self-test, it will conclude that there is an internal malfunction in the engine CPU. The HV control ECU will illuminate the MIL and set a DTC.
