DTC Diagnosis Procedure

WARNING:

Since hybrid vehicles and electric Nissan Ariya vehicles contain a high voltage battery, there is the risk of electric shock, electric leakage, or similar accidents if the high voltage component and Nissan Ariya vehicle are 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 disconnect the high voltage circuits before performing inspection or maintenance of high voltage system harnesses and parts.

• The removed service plug must always be carried in a pocket of the responsible worker or placed in the tool box during the procedure to prevent the plug from being connected by mistake.

• Be sure to wear insulating protective equipment before beginning work on the high voltage system.

• Never allow workers other than the responsible person to touch the Nissan Ariya vehicle containing high voltage parts. To keep others from touching the high voltage parts, these parts must be covered with an insulating sheet except when using them.

• Refer to HIGH VOLTAGE PRECAUTIONS : Precautions.

CAUTION:

Never bring the vehicle into the READY status with the service plug removed unless otherwise instructed in the Service Manual. A malfunction may occur if this is not observed.

DTC Diagnosis Procedure

WARNING:

Since hybrid vehicles and electric Nissan Ariya vehicles contain a high voltage battery, there is the risk of electric shock, electric leakage, or similar accidents if the high voltage component and Nissan Ariya vehicle are 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 disconnect the high voltage circuits before performing inspection or maintenance of high voltage system harnesses and parts.

• The removed service plug must always be carried in a pocket of the responsible worker or placed in the tool box during the procedure to prevent the plug from being connected by mistake.

• Be sure to wear insulating protective equipment before beginning work on the high voltage system.

• Never allow workers other than the responsible person to touch the Nissan Ariya vehicle containing high voltage parts. To keep others from touching the high voltage parts, these parts must be covered with an insulating sheet except when using them.
