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

LI-ION BATTERY
Because hybrid vehicles and electric vehicles contain a high voltage battery, there is a risk of
electric shock, electric leakage, or similar accidents if the vehicle is handled incorrectly. Be sure to fol-
low the correct work procedures when performing inspection and maintenance.
WARNING:
• Be sure to remove the service plug in order to shut off the high voltage circuits before performing
inspection or maintenance of high voltage system harnesses and parts.
• Be sure to put the removed service plug in pocket and carry it or store it in a tool box or other con-
tainer so that another person does not accidentally connect it while work is in progress.
• Be sure to put on insulating protective gear before beginning work on the high voltage system.
• Clearly identify the persons responsible for high voltage work and ensure that other persons do not
touch the vehicle. When not working, cover high voltage components with an anti-static cover sheet
or similar item to prevent contact with other persons.
• Refer to
EVB-7, "High Voltage Precautions"
.
CAUTION:
There is the possibility of a malfunction occurring if the vehicle is changed to READY status while the
service plug is removed. Therefore do not change the vehicle to READY status unless instructed to do
so in the Service Instruction.
REMOVAL
WARNING:
Prepare for work on the high-voltage system. Refer to
GI-33, "How to Disconnect High Voltage"
.
1. Lift up the vehicle and remove the Li-ion battery undercover.
2. Remove the harness clamp and disconnect the Li-ion battery
high-voltage harness connector .
DANGER:
•
There is the danger of electric shock caused by
contact with the terminals. Be sure to wear insulated pro-
tective gear.
•
Because there is the danger of electric shock, imme-
diately insulate disconnected high voltage connectors and terminals with insulating tape.
• Follow the procedure below to disconnect the high-voltage harness connector.
3. Disconnect the Li-ion battery heater harness connector .
DANGER:
•
There is the danger of electric shock caused by
contact with the terminals. Be sure to wear insulated pro-
tective gear.
