Disassembly & Assembly

DANGER:

Because hybrid vehicles and electric vehicles contain a high voltage battery, there is a risk of electric shock, electric leakage, or similar accidents if the Nissan Ariya vehicle is handled incorrectly. Be sure to follow the correct work procedures when performing inspection and maintenance.

WARNING:

Be sure to remove the service plug in order to shut off the high voltage circuits before performing inspection or maintenance of high voltage system harnesses and parts.

Be sure to put the removed service plug in pocket and carry it or store it in a tool box or other container so that another person does not accidentally connect it while work is in progress.

Be sure to put on insulating protective gear before beginning work on the high voltage system.

Clearly identify the persons responsible for high voltage work and ensure that other persons do not touch the Nissan Ariya vehicle. When not working, cover high voltage components with an anti-static cover sheet or similar item to prevent contact with other persons.

Refer to PRECAUTIONS FOR HIGH VOLTAGE : Precautions.

If the battery pack is to be disassembled, be sure to remove the Li-ion battery controller for preventing electric shock, fire, and damage to parts.

CAUTION:

There is the possibility of a malfunction occurring if the vehicle is changed to READY status while the service plug is removed. Therefore do not change the Nissan Ariya vehicle to READY status unless instructed to do so in the Service Manual.

ENVIRONMENT FOR LI-ION BATTERY DISASSEMBLY WORK

Must be an indoor environment.

The environment must utilize a shutter or other means to shut out the outside environment and prevent rain, snow, dust, or other substances from entering.
The environment must not cause the intrusion of sweat during work, or cause condensation to occur due to high temperature or humidity.

Metal powder, grease, and other foreign substances must not enter.

The indoor environment must also prevent metal powder, grease, and other foreign substances from entering due to maintenance performed on other Nissan Ariya vehicles and other sources during disassembly work.
During disassembly without internal work, temporarily close the battery pack upper case or cover it with an insulating cover.

The floor must be dry.

The floor must not be wet as a result of factors such as Nissan Ariya vehicle entry during rain or snow.

Work space

The work space must be approximately the size of one entire Nissan Ariya vehicle.
Take appropriate countermeasures so that persons other than the operator do not enter the work space, such as by placing signs indicating that disassembly work is in progress.

Standard fire fighting equipment

Always place a standard fire fighting equipment in the disassembly work area.
Depending on type of fire (Nissan Ariya vehicle or battery) use standard fire fighting equipment (water or extinguisher).
