Diagnosis Procedure
INFOID:0000000010121080
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.

With CONSULT
1. Select “Self Diagnostic Result” mode of “HV BAT” using CONSULT.
2. Check to see if “P3049”-“P3060” (CELL CONT ASIC VOLT related codes) or “P3375”-“P33A4” (CELL
OVER DISCHARGE related codes) is detected simultaneously with “P3097”-“P30A2”.
Is P3049-P3060 or P3375-P33A4 detected?
YES-1 >> “P3049”-“P3060” are detected simultaneously.
• When “P3049”-“P3054” are detected simultaneously, perform the diagnosis procedure of
“P3049”-“P3054”. Refer to
• When “P3055”-“P3060” are detected simultaneously, perform the diagnosis procedure of
“P3055”-“P3060”. Refer to
YES-2 >> “P3375”-“P33A4” are detected simultaneously.
• When “P3375”-“P3380” are detected simultaneously, perform the diagnosis procedure of
“P3375”-“P3380”. Refer to
EVB-122, "Diagnosis Procedure"
.
• When “P3381”-“P338C” are detected simultaneously, perform the diagnosis procedure of
“P3381”-“P338C”. Refer to
EVB-126, "Diagnosis Procedure"
• When “P338D”-“P3398” are detected simultaneously, perform the diagnosis procedure of
“P338D”-“P3398”. Refer to
EVB-130, "Diagnosis Procedure"
• When “P3399”-“P33A4” are detected simultaneously, perform the diagnosis procedure of
“P3399”-“P33A4”. Refer to
EVB-133, "Diagnosis Procedure"

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
.
>> GO TO 3.
3.
CHECK CONNECTION STATUS
1. Power switch OFF.
2. Check connection status of Li-ion battery controller harness connector and module harness connector.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Recover the connection status.
4.
CHECK HARNESS BETWEEN LI-ION BATTERY CONTROLLER AND MODULE
1. Disconnect Li-ion battery controller harness connector and Module harness connector.
2. Refer to below table and continuity between Li-ion battery controller and Module, according to detected
DTC.
