DTC CONFIRMATION PROCEDURE

1.

CHECK LI-ION BATTERY AVAILABLE CHARGE GAUGE

Check the indication of the Li-ion battery available charge gauge.

NOTE:

Check 12 segments for lighting status.
Is the lighting status 1 Segment or none?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

DISCHARGE OF LI-ION BATTERY

1. Set the vehicle to READY.

2. Set the vehicle, according to the following conditions.

3. Let the Li-ion battery discharge until the Li-ion battery available charge gauge shows segment 1 or below.

>> GO TO 3.

3.

CHARGE OF LI-ION BATTERY

1. Charge the Li-ion battery by normal charge until the level reaches full charge.

2. After the completion of normal charge, check that the indication of the Li-ion battery available charge

gauge shows 12 segments.

>> GO TO 4.

4.

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 P33ED detected?

YES

>> Refer to 

EVB-156, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000010121158

1.

CHECK DATA MONITOR OR FREEZE FRAME DATA (FFD)

With CONSULT

1. Select “DATA MONITOR” or “FFD”.

2. Check to see if there is a cell voltage which largely differ from the others.
Is there any abnormal cell?

Diagnosis Procedure

INFOID:0000000010121160

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.

PRECONDITIONING

WARNING:

Disconnect the 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-201, "LI-ION BATTERY CONTROLLER : Removal and

Installation"

.

>> GO TO 2.

2.

CHECK INSTALLATION CONDITION OF LI-ION BATTERY HEATER

Check the main body of Li-ion battery heater for installation condition.
Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Tighten the mounting nut of the Li-ion battery heater to the specified torque. Refer to 

EVB-214,

"LI-ION BATTERY HEATER : Exploded view"

.

3.

CHECK CONNECTION STATUS OF LI-ION BATTERY HEATER CONNECTOR

Check the connection status of the Li-ion battery heater connector.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Restore the connection status of the Li-ion battery heater connector.

4.

CHECK RESISTANCE OF LI-ION BATTERY HEATER
