Is P3300 detected?
YES- .
NO- INSPECTION END


Diagnosis Procedure


WARNING:
- Because hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are handled incorrectly. Be sure to follow the correct work procedures when performing inspection and maintenance.
- Be sure to remove the service plug in order to shut off the high voltage circuits before performing inspection or maintenance of high voltage system harnesses and parts.
- Be sure to put the removed service plug in your pocket and carry it with you so that another person does not accidentally connect it while work is in progress.
- Be sure to wear insulating protective gear consisting of glove, shoes and glasses/face shield before beginning work on the high voltage system.
- Clearly identify the persons responsible for high voltage work and ensure that other persons do not touch the vehicle. When not working, cover high voltage parts with an insulating cover sheet or similar item to prevent other persons from contacting them.
- High Voltage Precautions.

CAUTION:
There is the possibility of a malfunction occurring if the vehicle is changed to READY status while the service plug is removed. Therefore do not change the vehicle to READY status unless instructed to do so in the Service Manual.

1. PERFORM SELF-DIAGNOSIS-1

WITH CONSULT

NO- GO TO 2.

2. PERFORM SELF-DIAGNOSIS-2

WITH CONSULT
1.Select "Self Diagnostic Result" mode of "HV BAT" using CONSULT.
Is DTC detected?
YES-1- If P30EF is detected, P30EF.
YES-2- If P3374 is detected, P3374.
NO- GO TO 3.

3. PRECONDITIONING


WARNING:
Shut off high voltage circuit. How to Cut Off High Voltage.
- GO TO 4.

4. CHECK CONNECTION OF HIGH VOLTAGE HARNESS

Check the connection between the following high voltage parts and the high voltage harness for deterioration in terminals and improper fit.

- Traction motor
- Electric compressor
Is the inspection result normal?
YES- GO TO 5.
NO- Repair connection state of the harness or replace the harness.

5. CHECK HIGH VOLTAGE HARNESS

1.Remove Li-ion battery. Removal and Installation.
2.Check the connection between the following high voltage parts and the high voltage harness for deterioration in terminals and improper fit.
-Service plug
-Bus bar
-DC/DC converter
-Battery junction box
Is the inspection result normal?
YES- Replace Li-ion battery (battery pack). Removal and Installation.
NO- Repair or replace the malfunctioning part.
