Driving the vehicle without deactivating the inspection mode may damage the hybrid transaxle.

 With CONSULT-III

1. Touch “BACK” on the “CONSULT-III” screen to cancel the “ACTIVE TEST”.

2. Turn ignition switch OFF. The HV main system turns off simultaneously.

 Without CONSULT-III

1. Turn ignition switch OFF. The HV main system turns off simultaneously.

MODE 2
MODE 2 : Diagnosis Description

INFOID:0000000004211759

DESCRIPTION

This vehicle will perform the engine idling stop when the engine is warmed up and SOC is in good condition. If

engine running with vehicle stopped is necessary for service, the vehicle should be set in the inspection mode.

And if the vehicle is necessary to be set on a chassis-dynamometer, also the vehicle should be set in the

inspection mode.

2 types of inspection mode are available.

ACTIVATING PROCEDURE

CAUTION:

Driving the vehicle without deactivating the inspection mode may damage the hybrid transaxle.

NOTE:

• The idling speed in inspection mode is approximately 1,000 rpm. The engine speed increases to

1,500 rpm if the accelerator pedal is depressed by less than 60% with P range. If the accelerator

pedal is depressed by more than 60%, the engine speed increases to 2,500 rpm with P range. 

• If a DTC is set during the inspection mode, the high voltage battery warning light will stop blinking

and illuminate continuously.

• When the high voltage battery warning light illuminates during the inspection mode, deactivate the

inspection mode and check DTC.

 With CONSULT-III

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Shift the selector lever to P position.

3. Turn ignition switch ON.

4. Select “INSPECTION MODE 2” in “ACTIVE TEST” mode with CONSULT-III.

5. Check that high voltage battery warning light is blinking in the combination meter.

6. Turn ignition switch ON (READY).

 Without CONSULT-III

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Shift the selector lever to P position.

3. Turn ignition switch ON and perform the following steps 5 to 9 within 60 seconds.

4. Repeat the following procedure 3 times.

-

Fully depress the accelerator pedal.

-

Fully release the accelerator pedal.

5. Shift the selector lever to N position.

6. Repeat the following procedure 3 times.

-

Fully depress the accelerator pedal.

-

Fully release the accelerator pedal.

7. Shift the selector lever to P position.

8. Repeat the following procedure 3 times.

-

Fully depress the accelerator pedal.

-

Fully release the accelerator pedal.

Type

Condition

Mode 1
(Inspection mode - 2WD inspection)

• Engine runs continuously with the shift lever in P range.
• The traction control, that is initiated when the rotational difference between the front and 

rear wheels is excessive with the shift lever in any position other than P, is released.

Mode 2
(Inspection mode - 2WD chassis-dynamo)

• The traction control, that is initiated when the rotational difference between the front and 

rear wheels is excessive with the shift lever in any position other than P, is released.

INSPECTION MODE

9. Check that high voltage battery warning light is blinking in the combination meter.

If not blinking, perform steps 1 to 9 again.

10. Turn ignition switch ON (READY).

DEACTIVATING PROCEDURE

CAUTION:

Driving the vehicle without deactivating the inspection mode may damage the hybrid transaxle.

 With CONSULT-III

1. Touch “BACK” on the “CONSULT-III” screen to cancel the “ACTIVE TEST”.

2. Turn ignition switch OFF. The HV main system turns off simultaneously.

 Without CONSULT-III

1. Turn ignition switch OFF. The HV main system turns off simultaneously.

COMPONENT DIAGNOSIS

P0338-885

Description

INFOID:0000000004211760

The hybrid vehicle control ECU receives three engine speed signals such as NEI signal, GI signal and ENE

signal from the ECM. ENE signal is computed from crankshaft position sensor (POS) signal, GI signal and NEI

signal are from both sensor signals. ENE signal is sent via the CAN communication line.

The hybrid vehicle control ECU compares NEI signal and GI signal with ENE signal. If NEI signal or GI signal

is extremely low, the hybrid vehicle control ECU detects a malfunction.

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC confirmation procedure has been previously conducted, always turn ignition switch OFF and wait at

least 10 seconds before conducting the next test.

TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is more than 10.5V with igni-

tion switch ON.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Turn ignition switch ON (READY).

2. Shift the selector lever to P position.

3. Depress the accelerator pedal to start engine and keep the engine running for at least 5 seconds.

4. Check DTC.
Is DTC detected?

YES

>> Go to 

HBC-107, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000004211762

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.

>> GO TO 2.

2.

CHECK HARNESS BETWEEN HYBRID VEHICLE CONTROL ECU AND ECM

1. Turn ignition switch OFF.

2. Disconnect hybrid vehicle control ECU harness connector E66.

3. Disconnect ECM harness connector E10.

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

DTC No.
