P0A1A-166 - Generator Control Module

DESCRIPTION

The MG ECU located in the inverter with converter assembly monitors its internal operation and it will set DTCs when it detects malfunctions. If any of the following DTCs are output, replace the inverter with converter assembly.





MONITOR DESCRIPTION

The MG ECU performs many diagnostic tests to verify proper operation of internal ECU systems. In this diagnostic monitor, the MG ECU checks for an R/D (Resolver/Digital Converter) malfunction involving the generator resolver. If MG ECU detects an R/D error, it will conclude that there is an internal malfunction involving the generator resolver. The power management control ECU (HV CPU) will illuminate the MIL and set a DTC.
