Diagnosis Procedure
INFOID:0000000010121113
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.

2. Remove battery pack upper case. Refer to
EVB-191, "BATTERY PACK UPPER CASE : Removal and
.
>> GO TO 3.
3.
CHECK HARNESS BETWEEN MODULE AND LI-ION BATTERY CONTROLLER
1. Disconnect voltage detection terminal of bus bar and Li-ion battery controller harness connector.
2. Refer to below table and check the continuity between Li-ion battery controller and corresponding bus
bar .
