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.

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.

WARNING:

Prepare for work on the high-voltage system. Refer to HOW TO DISCONNECT HIGH VOLTAGE : Precautions.
