Description

INFOID:0000000004211885

A resolver is a sensor that detects the position of the magnetic poles, which are indispensable for ensuring

highly efficient control of MG2 and MG1.

The resolver stator contains an excitation coil and 2 detection coils. The gap between the stator and rotor

changes as the rotor turns because the rotor is oval shaped. An alternating current with a predetermined fre-

quency flows through the excitation coil, and detection coils S and C output alternating currents in accordance

with the sensor rotor position.

The MG ECU detects the absolute position of the rotor according to the phases of detection coils S and C and

the height of their waveforms. Furthermore, the CPU calculates the amount of change in the position within a

predetermined length of time, in order to use the resolver as a speed sensor.

The MG ECU monitors signals output from the motor resolver and detects malfunctions.

DTC Logic

INFOID:0000000004211886

DTC DETECTION LOGIC

The MG ECU monitors the motor resolver output signal. If the MG ECU detects output signals that are out of

the normal range or specification, it will conclude that there is a malfunction in the motor resolver. The hybrid

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

Diagnosis Procedure

INFOID:0000000004211887

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 for output DTCs again after the repair has been completed. If P0A78-286 or P0A7A-324 is output,

replace the inverter with converter assembly.

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

converter assembly.

• If the problem symptom cannot be reproduced, performing a road test on a road on which the vehicle tends

to vibrate will make it easier to reproduce the symptom.

• If INF code 243 is output, there may be an interphase short in the motor resolver circuit due to an intrusion of

water into the resolver. Therefore, if the problem symptom cannot be reproduced, replace the hybrid tran-

saxle last.

Description

INFOID:0000000004211888

A resolver is a sensor that detects the position of the magnetic poles, which are indispensable for ensuring

highly efficient control of MG2 and MG1.

The generator resolver structure and method of connection with the inverter with converter assembly are the

same as those of the motor resolver.

The inverter with converter assembly monitors output signals from the generator resolver and detects mal-

functions.

DTC Logic

INFOID:0000000004211889

DTC DETECTION LOGIC

The MG ECU monitors the generator resolver output signal. If the MG ECU detects output signals that are out

of the normal range or specification, it will conclude that there is a malfunction of the generator resolver. The

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