DESCRIPTION
The inverter contains a three-phase bridge circuit, which consists of 6 power transistors (IGBTs) each for the generator (MG1) and motor (MG2). The inverter converts high-voltage direct current from the HV battery into three-phase alternating current for the generator (MG1) and motor (MG2); it also converts three-phase alternating current supplied by generator (MG1) and motor (MG2) into direct current for the HV battery. The motor generator control ECU (MG ECU) controls the actuation of the power transistors (IGBTs). The inverter transmits information necessary for control, such as amperage and voltage, to the motor generator control ECU (MG ECU).
The motor generator control ECU (MG ECU) uses an inverter voltage sensor, which is built into the inverter, to detect boosted high voltage (VH) and allow control of the voltage boost.
The inverter voltage sensor outputs voltage that fluctuates between 0 to 5 V according to changes in VH.
The motor generator ECU monitors the inverter voltage sensor and detects the following malfunctions.

- Connect the Techstream to the DLC3.
- Turn the power switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off and wait for 2 minutes or more.
- Turn the power switch on (IG) and turn the Techstream on.
- Turn the power switch on (READY) and wait for 5 seconds or more.
- Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform driving pattern again.
