9. Install the service plug retainer .

WARNING:

To prevent electric shock, wear insulated protective

gear and use insulated tools.

10. Perform a battery pack air leak inspection. Refer to

EVB-256, "Inspection"

CAUTION:

If air leakage occurs, remove the battery pack upper case and wipe off the adhesive, then apply

new dam rubber and apply adhesive again. (Proceed to Step 4.)

11. Spray primer surfacer (anti-corrosion primer) (A) into cracks in

the periphery of the battery pack adhesive.

WARNING:

To prevent electric shock, wear insulated protective

gear.

CAUTION:

• After the battery pack is assembled, it can be installed into the vehicle. However the battery pack

must not be subjected to any external force (such as high-pressure washing or parking in a location

which strains the vehicle body) for approximately 3 hours after installation.

• Be sure to reinstall the high voltage harness clips in their original positions. If a clip is damaged,

replace it with a new clip before installing.

• After assembling the battery pack, perform an electric equipotential test.

• Check the following items after installing battery pack: Refer to

EVB-256, "Inspection"

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 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"

• If the battery pack is to be disassembled, be sure to remove the Li-ion battery controller for prevent-

ing electric shock, fire, and damage to parts.

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 Manual.

ENVIRONMENT FOR LI-ION BATTERY DISASSEMBLY WORK

1. Must be an indoor environment.

• The environment must utilize a shutter or other means to shut out the outside environment and prevent

rain, snow, dust, or other substances from entering.

• The environment must not cause the intrusion of sweat during work, or cause condensation to occur

due to high temperature or humidity.

2. Metal powder, grease, and other foreign substances must not enter.

• The indoor environment must also prevent metal powder, grease, and other foreign substances from

entering due to maintenance performed on other vehicles and other sources during disassembly work.

• If there is a risk of the above substances entering, take appropriate countermeasures, such as use of a

vinyl curtain or an equivalent to shut out the outside environment.

3. The floor must be dry.

• The floor must not be wet as a result of factors such as vehicle entry during rain or snow.

4. Work space

• The work space must be approximately the size of one entire vehicle.

• Take appropriate countermeasures so that persons other than the operator do not enter the work space,

such as by placing signs indicating that disassembly work is in progress.

5. Standard fire fighting equipment

• Always place a standard fire fighting equipment in the disassembly work area.

• Depending on type of fire (vehicle or battery) use standard fire fighting equipment (water or extin-

guisher).

REMOVAL

1. Remove the battery pack upper case.

EVB-191, "BATTERY PACK UPPER CASE : Removal and Installa-

tion"

2. Disconnect the low-voltage harness connector of the Li-ion

battery controller.

WARNING:

To prevent electric shock, wear insulated protective

gear.

3. Remove the Li-ion battery controller mounting nuts , then

remove the mounting bolts .

WARNING:

To prevent electric shock, wear insulated protective

gear and use insulated tools.

4. Disconnect the high-voltage harness connector , then remove

the Li-ion battery controller.

WARNING:

•

To prevent electric shock, wear insulated protective

gear.
