2016 NISSAN MURANO HYBRID Dismantling Guide

3. Preparation for Dismantling
DANGER
• Failure to properly shut down the high-voltage electrical 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.
• If it is necessary to touch any of the high-voltage harnesses or components you
must
always wear appropriate PPE to avoid electrical shock. PPE must always be worn
when touching or working on high-voltage components. Shut down the high-voltage
system by following the steps outlined in 3-4.1 High-voltage System Shut-Down
Procedure

(DG–21) . Wait approximately ten (10) minutes for complete discharge of the
high-voltage

capacitor after the high-voltage system has been shut down. • NEVER assume the Murano HYBRID is shut OFF simply because it is quiet.
•

If it becomes necessary for the dismantler to leave the vehicle, place a “DANGER” sign
[for example, refer to 5. Storing the Vehicle (DG–37)
on the vehicle to alert other people
that

the vehicle contains a high-voltage battery.
• If the READY indicator is ON the high-voltage system is active.
•

If possible, be sure to check the READY indicator on the instrument cluster and
verify

that the READY indicator is OFF and the high-voltage system is stopped.

3-2 Personal Protective Equipment (PPE) and Insulated Tools
3-2.1
Personal Protective Equipment (PPE) Protective Wear Control
Perform an inspection of the Personal Protective Equipment (PPE) items before beginning work. Do not use
any damaged PPE items.
3-2.2 Daily Inspection
This inspection is performed before and after use. The worker who will be using the items should perform
the inspection and check for deterioration and damage. • Insulated rubber gloves should be inspected for scratches, holes and tears. (Visual check and airleakage test)
• Insulated safety boots should be inspected for holes, damage, nails, metal pieces, wear or other problems on the soles. (Visual check)
• Insulated rubber sheet should be inspected for tears. (Visual check)
3-2.3 Insulated Tools
When performing work at locations where high-voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
3-3 Discharge Procedures DANGER
Do not perform this procedure if the battery is damaged. If you are unsure of battery
damage,

use extreme caution and wear appropriate Personal Protective Equipment (PPE) .
High-voltage battery discharging must take place before dismantling. Sufficient discharging can be achieved
by following these steps.
1. Place the shift selector into the Park (P) position
2. Apply the parking brake.
3. Set wheel chocks to ensure the vehicle is completely immobilized.
4. Fasten the driver seat belt and close the driver door.
5. Apply foot brake and press the ignition switch to turn the system ON. Confirm READY indicator in instrument cluster turns ON.
a.
If the engine starts, leave the engine running until reaching normal operating temperature
and the idling stops. It may take more than 10 minutes for complete engine warm up and
idling to stop.
b. If the engine is at normal operating temperature and does NOT start, move on to next step.
6. Remove the shift lock cover (A) using a suitable tool.
7. Push down the shift lock (C) as shown in the illustration.
8. Push the shift selector button (B) and move the shift selector to Neutral (N) position (D) while holding down
the shift lock.
NOTE:
DO NOT press accelerator or foot brake after
moving the shift selector to the Neutral (N)
position. Otherwise high-voltage battery will start
to be charged. C B

AAYIA0459ZZDG–19

NOTE:
The
engine must not be running at this time. If the engine has restarted, repeat the
previous steps.
9. Release the parking brake.
10. Unbuckle the seat belt and open the driver door. The READY indicator should remain ON
and

the engine should not be running.
11.
Turn ON electric devices such as headlamps, A/C (set to the coldest temperature) and rear window
defogger to discharge the high-voltage battery. Allow approximately 15 minutes to discharge.
Discharge is complete when the READY indicator (B) (green) turns OFF, the hybrid system
warning

indicator (C) (orange) turns ON and the message display indicates “Li-ion battery low”.
12. Press the ignition switch (A) to turn the system OFF.
Please contact following number if the vehicle could not be discharged. • 1-800-647-7261 (US) or 1-800-387-0122 (Canada)

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).
