NISSAN PATHFINDER HYBRID 2014 R52 / 4.G Dismantling Guide

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 Li-ion
battery is deformed, broken or cracked, appropriate PPE must always be used and the Li-ion battery and
high voltage components must not be touched.
•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) . 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 voltagecomponents.
•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 12V battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though the
12V 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 12V system will remain active even after the 12V 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 12V system and high voltage systemcontinuously.
Before disconnecting the 12V 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 12V battery is disconnected,
power controls will not operate.

Powering Down the High Voltage System
The high voltage system can be shut down with any 1 of the following procedures:• Turn OFF the power switch and disconnect the 12V battery. Refer to
Primary Procedure (DG–23).
• Remove the underhood fuse for the high voltage control system and disconnect the 12V battery. Refer to
Alternate Procedure 1 (Removing Fuses) (DG–25).
• Remove the service plug and disconnect the 12V battery. Refer to
Alternate Procedure 2 (Remove
Service Plug) (DG–27)
.
DG–22

Primary Procedure
NOTE:Before disconnecting the 12V battery terminal, if necessary, lower the windows, adjust the
steering column, adjust the seats, unlock the doors, etc. Once 12V 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
12V battery negative cable access.
If the READY indicator does not turn off, refer to
Alter-
nate Procedure 1 (Remove Fuses) (DG–25)
4. If possible, keep the NISSAN Intelligent Key® at least 5 meters (16 feet) away from the vehicle.

5. Pull release handle (1) and pull up release lever (2) to open hood.
6. Remove traction motor inverter cover (1) .
7. Disconnect negative (-) battery cable and cover it withinsulated 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
Dismantling Information (DG–41).

Alternate Procedure 1 (Remove Fuses)
NOTE: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 notoperate.
1. Pull release handle (1) and pull up release lever (2) to open the hood.
2. Release clips (A) and remove fuse box cover (1) .
: Vehicle front
3. Remove IGCT RLY fuse (F/L V 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.

Alternate Procedure 2 (Remove Service Plug)
•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 Li-ion 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 12V battery terminal, if necessary, lower the windows, adjust the
steering column, adjust the seats, unlock the doors, etc. Once 12V 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 the
next steps.
