Monitor Description
WARNING: This page is about a different variant/trim than selected.
The MG ECU performs many diagnostic tests to verify proper operation of internal ECU systems. For one of these diagnostics, the MG ECU checks the result of the generator CPU self-test. If the MG ECU detects a "Fail" from the generator CPU self-test, it will conclude that there is an internal malfunction in the generator CPU. The hybrid vehicle control ECU will illuminate the MIL and set a DTC.
