P0aa6-23 Hv Battery Voltage System Isolation

DTC Description

2WD models

A monitoring system for decrease of insulation resistance is built-in to the Li-ion battery. The VCM receives an insulation resistance decrease signal from the LBC and monitors the insulation resistance of the high voltage circuit.

NOTE:

  • Even if the insulation between the quick charge relay and the quick charge port decreases, the DTC “P0AA6-23” is not detected. In that case, when quick charge is performed, the insulation check that is performed by the quick charger becomes NG and quick charge does not start.

  • Even if the insulation between the normal charge port and the on-board charger decreases, the DTC “P0AA6-23” is not detected. In that case, when normal charge is performed, the “Fault” lamp of the EVSE control box starts blinking and normal charge does not start.

DTC Diagnosis Procedure

DANGER:

Since hybrid vehicles and electric 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:
