VIN AND DATE:
Built before 1N4AZ0CP(*)EC 332878 / Jan 30, 2014

IF YOU CONFIRM
The EV warning light is ON.
And
CHARGER / PD MODULE (Power Delivery Module or PDM) DTC P0A94 (DC/DC
Converter) and/or B2902 (PDM Memory Error) are stored.
And
The vehicle’s current CHARGER / PD MODULE software version is in “Table A” on page 9.


Refer to step 20 on page 9 in the SERVICE PROCEDURE to check current
CHARGER / PD MODULE software version.

ACTION
Reprogram the CHARGER / PD MODULE using the Service Procedure and CONSULT-III
plus (C-III plus) starting on the next page.
IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you will be performing.
You MUST closely follow the entire SERVICE PROCEDURE as it contains information that is essential to
successfully completing this repair.
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.

SERVICE PROCEDURE

NOTE: Follow all cautions, warnings, and notes in the Electronic Service Manual (ESM)
when working on or near a High Voltage (HV) System or Supplemental Restraint
System (SRS), such as an airbag.

IMPORTANT: Before starting, make sure:



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. Use C-III plus to perform Self Diagnosis for all systems and erase
all DTCs.

1. Connect the plus VI to the vehicle, and then to the CONSULT PC with the USB cable.
CAUTION: Make sure the plus VI is securly connected. If the plus VI connections
are loose during reprogramming, the process will be interrupted and the Module
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 Module May
be damaged.

3. Connect the GR8 (Multitasking Battery Diagnostic Station) to the vehicles 12V battery.


Set the GR8 to ECM power supply mode.
CAUTION: Do not charge the High Voltage (HV) Lithium Ion battery during
reprogramming or vehicle component damage may occur.
NOTE: Battery voltage must stay between 12 volts and 13.5 volts or reprogramming
may not start or be temporarily stopped. Returning battery voltage within the 12 -13.5
volt range will resume the reprogramming procedure.
CAUTION: Be sure the GR8 is connected securely to the 12V battery. Make sure
the battery voltage stays between 12.0V and 13.5V during reprogramming. If the
battery voltage goes out of this range during reprogramming, the Module may be
damaged.

4. 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 Module may be damaged.

5. Depress the vehicle’s power (“ignition”) switch twice without depressing the brake pedal.


The meter and gauges will illuminate.
CAUTION: Do Not set the vehicle in “READY to drive” mode or vehicle component
damage may occur.

6. Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC,
blower, rear defogger, audio, NAVI, seat heater, steering wheel heater, etc.
 Check to see if the timer for “charging” or “climate control” is on. If on, turn it off and
make sure to turn it back on after reprogramming.
NOTE: For charging timer on vehicles with navigation – write down which days are
OFF, Timer 1 or Timer 2.
IMPORTANT: Make sure to turn OFF all vehicle electrical loads. Make sure the
battery voltage stays between 12.0V and 13.5V during reprogramming. If the battery
voltage goes out of this range during reprogramming, the Module may be damaged.

7. Turn ON the CONSULT PC.

8. Select CONSULT-III plus (open C-III plus).
NOTE: Make sure all applications other than C-III plus are closed.
