b. Use an insulated torque driver (A) and tighten the voltage detec-
tion terminal mounting screws to the prescribed torque.
DANGER:
•
There is the danger of electric shock caused by
contact with the terminals. Be sure to wear insulated pro-
tective gear and use insulated tools.
•
This work must not be performed by multiple opera-
tors because there is a risk of electric shock if the operators contact one another.
c. Tighten the module terminal mounting bolts in numerical order as shown in the figure.
• When tightening of 1 – 16 is completed, install the left-side bus bar cover.
• When tightening of 17 – 32 is completed, install the right-side bus bar cover.
• When tightening of 33 – 48 is completed, install the center bus bar cover.
DANGER:
•
There is the danger of electric shock caused by contact with the terminals. Be sure to wear
insulated protective gear and use insulated tools.
•
This work must not be performed by multiple operators because there is a risk of electric
shock if the operators contact one another.
d. Install the bus bar cover .
WARNING:
To prevent electric shock, wear insulated protective gear.
CAUTION:
• Be careful not to install with the top and bottom facing in the wrong directions.
• After installation, check that the mating is not skewed.

7. Install the harness bracket , and to the rear module stack.
WARNING:
To prevent electric shock, wear insulated protective gear and use insulated tools.
CAUTION:
• 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.
• Check the following items after installing battery pack: Refer to

AIR LEAK INSPECTION
1. Remove the plug and install the adapter (A) of the air leak tester
[SST: KV99111400 ( — )].
WARNING:
To prevent electric shock, wear insulated protective
gear.
2. Install the gauge (A) of the air leak tester [SST: KV99111400
( — )].
WARNING:
To prevent electric shock, wear insulated protective
gear.
CAUTION:
The gauge is a precision instrument. Be careful not to drop
it when handling it.
3. Install the service plug.
DANGER:
There is the danger of electric shock caused by contact with the terminals. Be sure to wear
insulated protective gear.

NOTE:
Because the service plug location is open, install the service plug for sealing the case.
4. Use vinyl tape or similar means (A) for preventing air leakage
from the PTC harness connector.
• Use wide vinyl tape that is capable of covering all of the PTC
harness connector with one strip.
• Apply carefully so that no wrinkles in the tape occur.
WARNING:
To prevent electric shock, wear insulated protective
gear.
5. Use vinyl tape or similar means (A) to prevent air leakage from
the breather.
• Use wide vinyl tape that is capable of covering all of the
breather with one strip.
• Apply carefully so that no wrinkles in the tape occur.
WARNING:
To prevent electric shock, wear insulated protective
gear.
6. Follow the procedure below to check the battery case pressure.
WARNING:
To prevent electric shock, wear insulated protective gear.
a. Open the cock on the air leak tester.
CAUTION:
Do not operate the pump before opening the cock on the air
leak tester. Doing so may damage the gauge. If the pump is
operated before the cock is opened, first disconnect the air
pump hose to release the pressure.
b. Operate the air pump slowly and apply the specified inspection pressure inside the battery pack. If the
gauge pressure does not rise, or if the gauge reading fluctuates, check for the location of air leakage.
CAUTION:
• Operate the air pump carefully when applying pressure. If pressure is applied suddenly to the
gauge, the gauge may be damaged.
• Do not apply pressure of 2.0 kPa (0.0204 kg/cm
2
) or more to the battery case or air leak tester.

c.
Close the cock and wait for 1 minute.
d. Check that the air leak tester reading remains at or above the limit value.
e. If the pressure is below the limit value, check for the locations of air leakage.
NOTE:
Check for air leakage from the sound of air escaping when pressure is applied.
ELECTRIC EQUIPOTENTIAL TEST
After assembling the Li-ion battery pack, remove the battery pack upper case ground bolt , then measure
the resistance between the high-voltage harness connector flange ground bolts and the ground bolt seat
(location of coating peeling) .
WARNING:
To prevent electric shock, wear insulated protective gear.
If the result deviates from the standard value, check the following and correct the malfunction location.
• Ground bolt connection condition
• Corrosion on ground bolt mounting surface
• Presence of paint, oil, dirt, or other substance on ground bolt mounting surface
Repair limit
: 1.4 kPa (0.014 bar, 0.0142 kg/cm
2
, 0.203 psi)
Standard
: Less than 0.1
Ω
