3-4 How to Handle a Damaged Vehicle
3-4.1
High-voltage System Shut-Down Procedure
Any of the following procedures can shut down the high-voltage system. The dismantling operation can only
begin after shutting down the high-voltage system. If the vehicle is heavily damaged, for example the high-
voltage battery is deformed, broken or cracked, appropriate PPE must always be used and the high-voltage
battery and high-voltage components must not be touched. DANGER
• Failure to properly shut down the high-voltage system before the dismantling
procedures
are performed will result in serious injury or death from electrical shock. To
prevent serious injury or death, NEVER touch high-voltage harnesses or components
without always wearing appropriate Personal Protective Equipment (PPE) . Appropriate
PPE must always be worn when touching or working on high-voltage components.
• When contact with high-voltage components or high-voltage harnesses is
unavoidable,
or when there is risk of such contact, you must always wear appropriate
PPE. PPE must always be worn when touching or working on high-voltage
components. • The vehicle contains parts that contain powerful magnets. If a person who is wearing
a

pacemaker or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.
• Be sure to verify that the READY indicator is off (if possible) , and the high-voltage
system

is stopped.
• After the high-voltage system is shut down, please wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor. While waiting, do not operate any
vehicle functions.
• After shutting down the high-voltage system and removing the 12-volt battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though
the 12-volt battery negative (-) is disconnected, the Supplemental Restraint System (SRS)
air bag maintains voltage at least three (3) minutes. During this time, there is a possibility
of sudden SRS air bag inflation due to harness short circuit or damage and it may cause
serious injuries.
• The 12-volt system will remain active even after the 12-volt battery negative (-) terminal is removed while the high-voltage system is active.This is because the charging system will
not shut down and power will be supplied to the 12-volt system and high-voltage system
continuously.
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust the steering
column, adjust the seats, unlock the doors, open the liftgate, etc. as required. Once the 12-volt battery is
disconnected, power controls will not operate.
DG–21

Powering Down the High-voltage System
The
high-voltage system can be shut down with any 1 of the following procedures:• Turn OFF the ignition switch and disconnect the 12-volt battery. Refer to Primary Procedure
(DG–22) .
•

Remove the underhood fuse for the high-voltage control system and disconnect the 12-volt battery.
Refer to Alternate Procedure 1 (Remove Fuses) (DG–24).
•

Remove the service plug and disconnect the 12-volt battery. Refer to Alternate Procedure 2
(Remove

Service Plug) (DG–26) .
Primary

Procedure
NOTE:
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust
the steering column, adjust the seats, unlock the doors, etc. Once 12-volt battery is
disconnected, power controls will not operate.
1. If possible, check the READY indicator status in the instrument cluster. If it is on,
the

high-voltage system is active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch once to turn OFF the high-voltage system. Verify that the READY indicator is
off and then continue to the next steps to open the
hood for 12-volt battery negative cable access.
If the READY indicator does not turn off, refer to
Alternate Procedure 1 (Remove Fuses) (DG–24).
4.

If possible, keep the Nissan Intelligent Key® at least
5 meters (16 feet) away from the vehicle.P R N

5. Pull release handle located on the instrument panel and push the release lever under the hood
sideways to open hood.
6. Remove traction motor inverter cover.
7. Disconnect negative (-) battery cable and cover it with insulated tape.
8. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the battery cable has been disconnected.
9. Perform the dismantling operation. Refer to 6. Dismantling Information (DG–39). AAYIA0422ZZ

Alternate Procedure 1 (Remove Fuses)
NO
TE:
Before removing any fuses, if necessary, lower the windows, adjust the steering column,
adjust the seats, unlock the doors, etc. Once fuses are removed, power controls will not
operate.
1. Pull release handle located on the instrument panel and push the release lever under the hoodsideways to open hood.
2. Release clips on the narrow ends of the fuse box cover and remove it. : Vehicle front AAYIA0422ZZ

3. Remove IGCT RLY fuse (F/L IGCT RLY 50A) .
4.
If you cannot identify the correct fuse, remove all the
fuses. To avoid unintended reinstallation and risk of
electrical
shock and severe personal injury or death,
the dismantler should carry the fuse or fuses on his/her
person and cover the fuse box with insulated tape.
5. Remove traction motor inverter cover.
6. Disconnect negative (-) battery cable and cover it withinsulated tape.
7. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the fuse panel and battery cable have been disconnected.
8. Perform the dismantling operation. Refer to 6. Dismantling Information (DG–39). F/L V IGCT RLY 50A

Alternate Procedure 2 (Remove Service Plug)
DANGER
• Do not remove the service plug without always wearing appropriate Personal
Protective Equipment (PPE) to help protect the dismantler from serious injury or death
by electrical shock.
• Immediately cover the service plug socket with insulated tape. The high-voltage
battery
retains high-voltage power even when the service plug is removed. To avoid
electric shock, NEVER touch the terminals inside the socket. To avoid unintended reinstallation and risk of electrical shock and severe personal injury
or

death, the dismantler should carry the service plug on his/her person while work is in
progress.
NOTE: Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust
the steering column, adjust the seats, unlock the doors, etc. Once 12-volt battery is
disconnected, power controls will not operate.
1. If possible, check the READY indicator status in the instrument cluster. If it is on,
the

high-voltage system is active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch once to turn OFF the high- voltage system. Then verify whether the READY
indicator is off.
If the READY indicator does not turn off, continue to
step 4.
4. If possible, keep the Nissan Intelligent Key® at least 5 meters (16 feet) away from the vehicle.

3-4.2 Cutting the Vehicle Body
DANGER
• Do not cut into high-voltage related areas to avoid severe personal injury or death.
• Do not cut into the high-voltage battery to avoid severe personal injury or death.
• When removing parts, NEVER touch the high-voltage parts or the insides of the
exposed orange-colored high-voltage cables to avoid severe personal injury or
death. Appropriate Personal Protective Equipment (PPE) must always be worn when
touching or working on high-voltage components. To avoid unintended reinstallation and risk of electrical shock and severe personal injury or
death,

the dismantler should carry the fuses or service plug on his/her person while work
is in progress. Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of
severe

personal injury or death.
If approximately (10) minutes have passed since the dismantler shut down the high-voltage system
[refer to 3-4.1 High-voltage System Shut-Down Procedure (DG–21)], then the dismantler can cut the
vehicle

except for the high-voltage battery. DO NOT cut the high-voltage battery due to possible electrocution risk and electrolyte solution
leakage.
DG–29

SRS Air Bag System Components Location
The
SRS air bag system must not be cut as there is a risk of short circuit and unintentional deployment of
the SRS. However, the vehicle can be cut (except inflators) under the following conditions: • The front, side and curtain air bags have deployed.
• At least three (3) minutes have passed after the 12-volt battery negative (-) cable has beendisconnected and the high-voltage system has been shut down.
