Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Monitor Description
The MG ECU (in the Inverter with converter assembly Power control module) performs many diagnostic tests to verify proper operation of internal unit systems. In one of these tests, the MG ECU checks for an R/D (Resolver/Digital converter) malfunction involving the motor resolver. If the MG ECU detects an R/D converter error, it will conclude that there is an internal malfunction involving the motor resolver and the Hybrid vehicle control ECU assembly will illuminate the MIL and store a DTC.
