2011-2015 LEAF; REPLACEMENT HIGH VOLTAGE
BATTERY PACK
This bulletin has been amended to update the Applied Vehicles and Parts Information and to add
information to register the Li-ion Battery Controller (LBC).
Please discard the previous version.
APPLIED VEHICLES:
2011 – 2015 LEAF® (ZE0)
SERVICE INFORMATION
If the High Voltage (HV) Battery pack needs to be replaced for any reason:
2013 – 2015 LEAF

The HV Battery Pack listed in the Parts Information table is a direct replacement and
does not require any additional parts.
NOTE:
o Refer to the applicable Electronic Service Manual (ESM) section EVB EV
Battery System for the procedure to replace the HV Battery Pack.
o Refer to Service Information Overview on page 2 for additional services
required when replacing the HV Battery Pack.
2011 – 2012 LEAF

The HV Battery Pack listed in the Parts Information table can be retrofitted with the
list of additional parts and the Service Procedure starting on page 2.
IMPORTANT:
DO NOT “READ & WRITE” any Li-ion Battery Controller (LBC) data to the new HV
Battery Pack assembly.

Writing the old HV Battery Pack LBC data to the new HV Battery Pack assembly will
cause the vehicle to read only 8 bars of capacity and will require the LBC to be
replaced.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

NTB14-059a
Retrofitting HV Battery Pack
These procedures are to be performed ONLY by a Master Technician with current
LEAF certification.
Follow all Warning, Caution, and Danger instructions in the ESM.
DANGER:
 Touching high voltage components without using the appropriate protective
equipment will cause electrocution.
 Electric vehicles contain a high voltage battery. There is the risk of electric shock,
electric leakage, or similar accidents if the high voltage components and vehicle are
handled incorrectly. Be sure to follow the correct work procedures when performing
this procedure.
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 consisting of gloves, shoes, a face
shield and glasses before beginning work on the high voltage system.
 Never allow workers other than the responsible person to touch the 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.
 Erect the safety barriers around the vehicle to prevent un-authorized personnel from
entering high voltage work area.
CAUTION:
 Never turn the vehicle ignition to the READY status with the service plug removed
unless otherwise instructed in the ESM. A malfunction may occur if this is not
observed.

3. Check to see if the timer for “charging” or “climate control” is ON. If ON, turn OFF and
make sure to turn back ON after the HV battery pack is replaced.

For charging timer on vehicles with navigation – write down which days are OFF,
Timer 1 or Timer 2.
4. Remove the HV Battery Pack.

Use the procedures from the ESM for the following steps unless otherwise directed.
NOTE: Refer to the applicable ESM section EVB EV Battery System for the
procedure to replace the HV Battery Pack.
Figure 1 shows the new and old HV Battery Packs side by side.
NOTE: For 2013-2015 vehicles the new HV Battery Pack is a direct replacement and
does not require this retrofitting procedure.
