SERVICE INFORMATION
If the High Voltage (HV) Battery Pack needs to be replaced for any reason:

The 40 kWh HV Battery Pack listed in the Parts Information table, on page 26, is a
direct replacement for the 30 kWh HV Battery Pack and does not require any
additional parts.

The 30KWh HV battery pack is discontinued as of the publication of this bulletin.

For vehicles requiring HV Battery Pack replacement that are not covered by this
bulletin, VINS starting with 1N4AZ0, refer to NTB14-059.
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.
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.

Refer to the ESM for HV Battery Pack replacement, and then perform the following
procedures in order:
a. Register the New HV Battery Pack Assembly (below)
b. EV/HEV BATTERY GRADUAL CAP LOSS DATA CLEAR (page 9)
c. Register the HV Battery Installation Date (page 10)
d. Reprogram the Motor Control Unit (page 12)
Register the New HV Battery Pack Assembly
IMPORTANT: Before starting, make sure:

ASIST on the CONSULT PC has been synchronized (updated) to the current date.

All CONSULT-III plus (C-III plus) software updates (if any) have been installed.
HINT: An unregistered HV Battery Pack will set P3102 (Invalid Battery).
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.
1. Install the HV Battery Pack registration card into the CONSULT PC.
2. Attach the CONSULT PC to the vehicle.

Connect the plus VI to the vehicle.

Connect the AC adapter to the CONSULT PC.
3. Turn ON the CONSULT PC and then open C-III plus.
4. Depress the vehicle’s power (“ignition”) switch twice without depressing the



Most instructions for reprogramming with C-III plus are displayed on the CONSULT PC
screen.
Check to see if the timer for either charging or climate control is ON. If ON, turn them
OFF and make sure to turn them back ON after reprogramming.

Connect a battery maintainer or smart charger to the vehicle battery, set to
“power supply” mode.
If the vehicle battery voltage drops below 12.0V or rises above 13.5V during
reprogramming, the MCU may be damaged.

Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the MCU may be damaged.

Be sure to connect the AC Adapter.
If the CONSULT PC battery voltage drops during reprogramming, the process
will be interrupted and the MCU may be damaged.

Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.)
within range of the CONSULT PC and the VI. If Bluetooth® signal waves are
within range of the CONSULT PC during reprogramming, reprogramming may
be interrupted and the MCU may be damaged.
