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.

CONFIRMATION DRIVING PATTERN

HINT:
·

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Click hereEngine / Hybrid System>HYBRID / BATTERY CONTROL>MOTOR GENERATOR CONTROL SYSTEM>UTILITY



1.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

2.

Turn the ignition switch off and wait for 2 minutes or more.

3.

Turn the ignition switch to ON (READY) and wait for 5 seconds or more. [*1]

HINT:

[*1]: Normal judgment procedure.

The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.


4.

Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.

5.

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 the normal judgment procedure again.
