P0A1A / INF200
P0A1A-200, P0A1A-792, P0A1A-793Description
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 generator resolver. If MG ECU detects an R/D error, it will conclude that there is an internal malfunction involving the generator resolver. The hybrid vehicle control ECU will illuminate the MIL and set a DTC.
