2017 NISSAN LEAF First Responders Guide

3-3.1 High-voltage System Shut-Down Procedures
Any
of the following procedures can shut down and isolate the high-voltage system. The first response
operation should only begin after shutting down the high-voltage system. If the vehicle is heavily damaged,
for example the high-voltage battery is deformed, broken or cracked, appropriate Personal Protective
Equipment (PPE) must always be used and the high-voltage battery and high-voltage components must not
be touched. • Failure to properly shut down the high-voltage system before the Emergency
Response
Procedures are performed will result in serious injury or death from
electrical shock. To prevent serious injury or death, NEVER touch high-voltage
harnesses or components without always wearing appropriate Personal Protective
Equipment (PPE) . PPE must always be worn when touching or working on high-
voltage components
• When contact with high-voltage components or high-voltage harnesses is
unavoidable,
or when there is risk of such contact, you must always wear appropriate
PPE. PPE must always be worn when touching or working on high-voltage
components.

• If the charge connector is connected to the vehicle, remove it. Refer to
Removing the
Charge
Connector (FRG–19) .
• 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.
• Be sure to verify that the READY indicator is off and the high-voltage system is
stopped.
•

After the high-voltage system is shut down, please wait at least ten (10) minutes for
complete discharge of the high-voltage capacitor. While waiting, do not operate any
vehicle functions.
NOTE:
The high-voltage full discharge takes ten (10) minutes, but after five (5) minutes the
voltage has dropped below 60V.
• After shutting down the high-voltage system and removing the 12-volt battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though
the 12-volt battery negative (-) is disconnected, the Supplemental Restraint System (SRS)
air bag maintains voltage at least three (3) minutes. During this time, there is a possibility
of sudden SRS air bag inflation due to harness short circuit or damage and it may cause
serious injuries.
• Always shut down the high-voltage system before disconnecting the 12-volt battery. Not doing so may result in serious injury or death from electrical shock.
• The 12V system will remain active even after the 12-volt battery negative (-) terminal is removed while the high-voltage system is active. The high-voltage system is active
during any of the following conditions:
– charging indicator is turned ON
– READY indicator is turned ON
Refer to 1-1.2 Interior Component Location (FRG–6) for location of these indicators.
This

is because DC/DC converter will not shut down and power will be supplied to
the 12V system and high-voltage system continuously.

Indications the High-voltage System is ON
1. If the READY indicator is ON, the high-voltage system is active.
2.

The high-voltage system is active if any charge indicator
is ON (blue LEDs on top of the instrument panel) .
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, unlock the doors, and
open the rear hatch as required. Once 12-volt battery is disconnected, power controls will not operate. AAYIA0155ZZ

Powering Down the High-voltage System
The
high-voltage system can be shut down with any 1 of the following procedures:• Turn OFF the power switch anddisconnect the 12-volt battery.
Refer to Primary Procedure (FRG–22) .
•

Remove the fuses for the high-voltage control system and disconnect the 12-volt battery.
Refer to Alternate Procedure 1 (Remove Fuses) (FRG–23).
•

Remove the service plug and disconnect the 12-volt battery.
Refer to Alternate Procedure 2 (Remove Service Plug) (FRG–26).
Primary

Procedure
1. Check the READY indicator status. If it is ON, the high-voltage system is active.
2.

Place the selector lever in the Park (P) position.
3. Press the power switch once to turn OFF the high- voltage system. Then verify whether the READY indicator is OFF and continue to the next steps to
open

the hood for 12-volt battery negative cable access.
If the READY indicator does not turn off, refer
to Alternate Procedure 1 (Remove Fuses) (FRG–23)
4. If possible, keep the Nissan Intelligent Key® at least 5
meters (16 feet) away from the vehicle.
5. Open the hood. AAYIA0091ZZ
