VOLUNTARY SERVICE CAMPAIGN
2012 M35H BATTERY DETERIORATION MONITOR

CAMPAIGN ID #:

P2541

APPLIED VEHICLE:

2012 M35h - Hybrid (HY51)
Check Service Comm to confirm campaign eligibility.

INTRODUCTION
Infiniti is conducting a voluntary service campaign on certain 2012 M35h vehicles to reprogram the Lithium –ion
Battery Controller (LBC). In some cases the LBC may indicate the high voltage hybrid battery has deteriorated
when it has not. This reprogram will improve the LBCs accuracy for monitoring battery deterioration. This
procedure will be performed at no charge for parts or labor.

IDENTIFICATION NUMBER
Nissan has assigned identification number P2541 to this campaign. This number must appear on all
communications and documentation of any nature dealing with this campaign.

DEALER RESPONSIBILITY
Dealers are to correct each vehicle falling within the range of this campaign that enters the service department.
This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in
a dealer’s inventory.

Infiniti 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 Infiniti dealer to determine if this
applies to your vehicle.

SERVICE PROCEDURE
Reprogram HV BATTERY control unit

IMPORTANT: Before starting, make sure:
•

If the CONSULT PC has an active screen saver – disable it – turn it off.

•

ASIST on the CONSULT PC has been freshly synchronized (updated).

•

All C-III plus software updates (if any) have been installed.
NOTE: The CONSULT PC automatically gets applicable reprogramming data
during ASIST synchronization.

•

A screen print for warranty documentation can be done from the CONSULT PC during this process
while still connected to the vehicle.

•

No DTCs stored.
o Use C-III plus to perform Self Diagnosis for all systems.
o If there are any DTCs, diagnose, perform repairs, and erase DTCs before continuing.

1. Connect the plus Vehicle Interface (plus VI) to the vehicle.
•

Make sure to use the correct VI for C-III plus (plus VI).
CAUTION: Make sure the plus VI is securly connected. If the plus VI connection is loose during
reprogramming, the process will be interrupted and the related control unit may be damaged.

2. Connect the AC Adapter to the CONSULT PC.
CAUTION: Be sure to connect the AC Adapter. If the CONSULT PC battery voltage drops during
reprogramming, the process will be interrupted and the related control unit may be damaged.

3. Connect the USB cable between the CONSULT PC and the Plus VI.
4. Connect a 12 volt battery charger to the
vehicle at the underhood 12 volt Positive (+)
terminal.
•

Use the GR-8 (Battery and Electrical
Diagnostic Station) set to “Power Supply”
mode.

•

Connect the postive cable to the 12 volt
Positive (+) terminal and the negitive cable to
a metal bracket attached to the engine.

CAUTION : DO NOT use a standard battery charger for Hybrid vehicles. Make sure to connect the GR8 securely to the 12V battery. Make sure the battery voltage stays between 12.0V and 15.5V during
reprogramming. If the battery voltage goes out of this range during reprogramming, the related control
unit may be damaged.

5. Turn off all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range of the CONSULT PC
and the VI.
CAUTION: Make sure to turn off all external Bluetooth® devices. If Bluetooth® signal waves are within
range of the CONSULT PC and the VI during reprogramming, reprogramming may be interrupted and
the related control unit may be damaged.

6. Turn the ignition ON with the ready to drive indicator light OFF (not
illuminated).
•

The engine must not start or run during the reprogramming
procedure.

•

Make sure the dash warning lights are ON and the ready to drive
indicator light is OFF (not illuminated).

Ready to drive indicator light

7. Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC, blower, rear defogger,
audio, NAVI, seat heater, steering wheel heater, etc.
IMPORTANT: Make sure to turn OFF all vehicle electrical loads. Make sure the battery voltage stays
between 12.0V and 15.5V during reprogramming. If the battery voltage goes out of this range during
reprogramming, the related control unit may be damaged.
