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 its internal components. As part of those tests, the MG ECU checks CPU self-test results. If the MG ECU detects "Fail", it will conclude that there is an internal malfunction in that CPU. The hybrid vehicle control ECU will then illuminate the MIL and store a DTC.
