DESCRIPTION
The motor generator control ECU (MG ECU), which is built into in the inverter with converter assembly, detects the temperature of the boost converter using the boost converter temperature sensor 2 (lower). The motor generator control ECU (MG ECU) also detects malfunctions in the boost converter temperature sensor 2 (lower) and its wiring.
