Description

INFOID:0000000004211990

When three-phase alternating current flows through the three-phase windings of the stator coil, a rotating

magnetic field is generated in MG2. The system controls the rotation of the magnetic field in accordance with

the rotating position and speed of the rotor. As a result, the permanent magnets provided in the rotor are

pulled in the direction of rotation, generating torque. The generated torque is almost proportional to the

amount of current. The system controls MG2 speed by regulating the frequency of the alternating current. Fur-

thermore, the system properly controls the rotating magnetic field and the angle of the rotor magnets in order

to generate high torque in an efficient manner, even at high speeds.

DTC Logic

INFOID:0000000004211991

DTC DETECTION LOGIC

The MG ECU monitors the MG2 system. If the MG ECU detects a malfunction of the MG2 system, the hybrid

vehicle control ECU will illuminate the MIL and set a DTC.

Diagnosis Procedure

INFOID:0000000004211992

1.

PRECONDITIONING

• Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with

converter assembly, take safety precautions such as wearing insulated gloves and removing the service

plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent

other technicians from accidentally reconnecting it while you are working on the high-voltage system.

• After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage

connectors or terminals.

• Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with

converter assembly.

CHECK DTC OUTPUT (HYBRID SYSTEM)

1. Turn ignition switch ON.

2. Check DTC.

NOTE:

P0A90-509 may be set due to a malfunction which also causes DTCs in the table above to be set. In this

case, first troubleshoot the output DTCs in the table above.

Then, perform a test to attempt to reproduce the problems, and check that no DTCs are output.

Is DTC detected?

YES

>> Go to Diagnosis Procedure relevant to output DTC.

NO

>> GO TO 3.

3.

CHECK CONNECTOR CONNECTION CONDITION (INVERTER WITH CONVERTER ASSEMBLY CON-

NECTOR)

DTC DETECTION LOGIC

The MG ECU monitors MG1. If the MG ECU detects a reduction in the magnetic force of MG1 or an inphase

short, it interprets this as an MG1 failure. The hybrid vehicle control ECU will illuminate the MIL and set a DTC.
