DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1. Power switch ON and wait for 10 seconds or more.

2. Select “Self Diagnostic Result” of “HV BAT”.

3. Check DTC.
Is any DTC detected?

YES

>> Refer to 

EVB-119, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000010121116

DANGER:

Since 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.

WARNING:

• Be sure to remove the service plug in order to disconnect the high voltage circuits before perform-

ing inspection or maintenance of high voltage system harnesses and parts.

• The removed service plug must always be carried in a pocket of the responsible worker or placed in

the tool box during the procedure to prevent the plug from being connected by mistake.

• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses

before beginning work on the high voltage system.

• Never allow workers other than the responsible person to touch the vehicle containing high voltage

parts. To keep others from touching the high voltage parts, these parts must be covered with an insu-

lating sheet except when using them.

• Refer to 

EVB-7, "High Voltage Precautions"

.

CAUTION:

Never bring the vehicle into the READY status with the service plug removed unless otherwise

instructed in the Service Manual. A malfunction may occur if this is not observed.

1. Perform “All DTC Reading” with CONSULT.

2. Check “Self Diagnostic Result” of systems other than “HV BAT” if any DTC is detected. 
Is any DTC detected?

YES

>> After performing trouble diagnosis of detected DTC, GO TO 2.

NO

>> GO TO 2.

PRECONDITIONING

WARNING:

Disconnect high voltage. Refer to 

GI-33, "How to Disconnect High Voltage"

.

1. Remove Li-ion battery. Refer to 

EVB-181, "Removal and Installation"

.

2. Remove battery pack upper case. Refer to 

EVB-191, "BATTERY PACK UPPER CASE : Removal and

Installation"

.

>> GO TO 3.

3.

CHECK HARNESS BETWEEN MODULE AND LI-ION BATTERY CONTROLLER

With CONSULT

1. Power switch OFF.

2. Identify the malfunctioning module based on detected DTC.

3. Disconnect module harness connector and Li-ion battery controller harness connector.

4. Refer to below table and check the continuity between corresponding module and Li-ion battery controller.
