ACTION
1.

Perform the appropriate diagnostic procedure outlined in the Electronic Service
Manual (ESM).

2.

Refer to Table A on page 2 and page 3 to confirm if Electronic Control Module (ECM)
reprogramming is needed.

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.

IMPORTANT: Before starting the reprogramming procedure, 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.



The CONSULT PC is connected to the Internet (Wi-Fi or cable).

NOTE:


If you are not familiar with the reprogramming procedure, click here. This will link you
to the "CONSULT- III plus (C-III plus) ECM Reprogramming" general procedure.



Take the vehicle for a 10 minute drive in order to meet the following Idle Air Volume
Learn (IAVL) conditions:
 Engine coolant temperature: 70 -100°C
(158 - 212°F)
 Battery voltage: More than 12.9V (At idle)
 Transmission: Warmed up


After reprogramming is complete, you will be
required to perform Throttle Valve Closed
Position, Idle Air Volume Learn, Accelerator
Closed Position, and DTC erase.

Figure A

CAUTION:


Connect the GR8 to the 12V battery and select ECM Power Supply Mode.
If the vehicle battery voltage drops below 12.0V or above 15.5V during
reprogramming, the ECM may be damaged.



Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the ECM 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 ECM 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 ECM may be damaged.
