Diagnosis Procedure
INFOID:0000000010121151
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 Instruction. A malfunction may occur if this is not observed.
1.
CHECK SELF-DIAGNOSIS RESULTS OF LI-ION BATTERY CONTROLLER
With CONSULT
1. Select “Self Diagnostic Result” of “HV BAT”.
2. Check to see if “P0A1F”, “P3062” or “P33ED” is detected simultaneously with “P33E6”.
Is P0A1F, P3062 or P33ED detected?
YES-1 >> When “P0A1F” or “P3062” are detected simultaneously, Replace Li-ion battery controller. Refer to
EVB-181, "Removal and Installation"
YES-2 >> When “P33ED” is detected simultaneously, perform the diagnosis procedure of “P33ED”. Refer to
EVB-156, "Diagnosis Procedure"
NO
>> GO TO 2.
2.
CHECK FREEZE FRAME DATA (FFD)
With CONSULT
1. Check “FFD” when DTC is detected.

2. Calculate the average value of cell voltage by dividing “TOTAL BATTERY VOLTAGE” by 96 (the number
of cells).
3. Identify the minimum cell voltage and the maximum cell voltage from 96 cells.
4. Calculate voltage according to the following expressions to compare voltage between A and B.
Which voltage is larger, A or B?
A
>> Replace module including a cell of the maximum cell voltage. Refer to
(Front module stack) or
(Rear module stack). After replacing module, GO TO 3.
B
>> Replace module including a cell of the minimum cell voltage. Refer to
(Front module stack) or
(Rear module stack). After replacing module, GO TO 3.
3.
PERFORM CELL VOLTAGE LOSS INSPECTION
With CONSULT
1. Select “WORK SUPPORT” of “HV BAT.”
2. Select “CELL VOLTAGE LOSS INSPECTION.” Touch “START.”
3. Check “MINIMUM CELL VOLTAGE.”
Is “MINIMUM CELL VOLTAGE” 3,712 mV or less?
YES
>> GO TO 5.
NO
>> GO TO 4.
4.
DISCHARGE OF LI-ION BATTERY
With CONSULT
1. Set the vehicle to READY.
2. Set the vehicle, according to the following conditions.
3. Check “DATA MONITOR” and let the Li-ion battery discharge until the “MINIMUM CELL VOLTAGE”
reaches 3,712 mV or less.
NOTE:
The guide line is to discharge until the Li-ion battery available charge gauge indicates 2 segments or less.
For discharge time, refer to the following table.
Guideline for discharge time
Average cell voltage = “TOTAL BETTER VOLTAGE”
÷ 96 (the number of cells)
A = Maximum cell voltage

CHECK CELL OF VOLTAGE LOSS
With CONSULT
1. Check that “MINIMUM CELL VOLTAGE” is 3,712 mV or less. Touch “START.”
2. Check to see if a cell of which voltage is less than or equal to “CELL VOLTAGE LOSS JUDGMENT
VALUE” is displayed.
Is a cell displayed?
YES
>> Record applicable cell No. and then GO TO 6.
NO
>> Check the minimum cell voltage on the data monitor and replace a module which includes the
minimum cell voltage. Refer to
EVB-222, "FRONT MODULE STACK : Exploded View"

PRECONDITIONING
WARNING:
Disconnect high voltage circuit. Refer to
GI-33, "How to Disconnect High Voltage"
.
