The inverter with converter assembly (MG ECU) monitors its internal operation and detects malfunctions.
DTC Logic
DTC Detection Logic
The MG ECU (in the inverter with converter assembly) performs many diagnostic tests to verify proper operation of internal ECU systems. For this diagnostic monitor, 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. The hybrid vehicle control ECU will illuminate the MIL and set a DTC.
