Diagnosis Procedure

INFOID:0000000004212141

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.

>> GO TO 2.

CHECK DTC FOR ACU

1. Turn ignition switch ON.

2. Check DTC for ACU. Refer to

SRC-14, "CONSULT-III Function (AIR BAG)"

Is DTC detected?

YES

>> Go to diagnosis procedure relevant to output DTC.

CHECK HARNESS BETWEEN HYBRID VEHICLE CONTROL ECU AND ACU

1. Turn ignition switch OFF.

2. Disconnect hybrid vehicle control ECU harness connector E66.

3. Disconnect ACU harness connector M35.

4. Measure the resistance according to the value(s) in the table below.

Check for open

Check for short

OK or NG

>> GO TO 5.

>> GO TO 4.

DETECT MALFUNCTIONING PART

Check the following.

• Harness connectors M89, E64

• Harness continuity between hybrid vehicle control ECU and ACU

>> Repair open circuit or short to ground or short to power in harness or connectors.

CHECK INTERMITTENT INCIDENT

Refer to

GI-42, "Intermittent Incident"

• Check the connection and terminal contact pressure of connectors and wire harness between the hybrid

vehicle control ECU and ACU.

• Turn ignition switch ON, jiggle the connectors and wire harness.
Is the inspection result normal?

YES

>> Replace hybrid vehicle control ECU (See

HBC-644, "Removal and Installation"

>> Repair or replace harness or connectors.

Description

INFOID:0000000004212142

The hybrid transaxle assembly consists of the planetary gear unit, MG1, and MG2. The gear unit uses the

planetary gear to split engine output in accordance with a driving request while the vehicle is driven or the HV

battery is charged. MG2 assists engine output while increasing vehicle driving force. MG2 also converts the

energy, which is consumed in the form of heat during normal braking, into electrical energy and recover it into

the HV battery to effect regenerative braking. MG1 supplies power, which is used for charging the HV battery

or driving the MG2. It also controls the stepless transmission function of the hybrid transaxle by regulating the

amount of electricity generated to change MG1 speed. In addition, the MG1 is used as a starter motor to start

the engine. The transmission input damper absorbs the shock generated when the driving force from the

engine is transmitted.
