NISSAN PATHFINDER HYBRID 2014 R52 / 4.G Dismantling Guide

6. Dismantling Information
Removal or repair of the high voltage battery requires special tools and specific training. NISSAN strongly
recommends that only certified NISSAN dealer technicians perform these operations.
6-1 Precautions for Handling High Voltage Lithium-ion (Li-ion) Battery
•Because Pathfinder HYBRID contains a high voltage (Li-ion) battery, there is the
risk of electric shock, electric leakage, or similar accidents if the high voltage
components or vehicle is handled incorrectly. Be sure to follow the correct work
procedures when performing inspection and dismantling.
•
If it is necessary to touch any of the high voltage harnesses or components you must
always wear appropriate Personal Protective Equipment (PPE) and properly shut-down
the high voltage system by removing the service plug.
•
Be sure to always wear appropriate PPE before beginning work on the high voltage
system.
•
Be sure to remove the service plug in order to shut-down the high voltage system
before performing inspection or dismantling of high voltage system harnesses and parts.
•
If the vehicle is heavily damaged, for example the Li-ion battery is deformed,
broken, or cracked; appropriate PPE must always be used at all times to avoid electrical shock.
DG–41

•The colors of the high voltage harnesses and connectors are all orange. OrangeHigh
Voltage labels are applied to the Li-ion battery and other high voltage devices. Do not
touch the Li-ion battery or other high voltage devices without always wearing appropriate
PPE.
•
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 parts with an
insulating cover sheet and sign or similar item to prevent other persons from contactingthem.
•
Be sure to put the removed service plug in your pocket and carry it with you so
another person does not accidentally reinstall it while work is in progress.
•
The high voltage battery retains high voltage at all times. Personal Protective
Equipment (PPE) must always be worn when touching or working on high voltage
components to avoid risk of electrical shock and severe personal injury or death.
•
Immediately insulate disconnected high voltage connectors and terminals with
insulated tape.
•
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.
•
Because this vehicle uses components that contain high voltage and powerful
magnetism, do not carry any metal products which may cause short circuits, or any
magnetic media (cash cards, credit cards, etc.) which may be damaged when working on
the vehicle.
•
Keep removed Li-ion battery packs away from rain to avoid electric shock.
• Do not heat removed battery packs higher than 158° F (70° C) .
