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
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) plus software updates (if any) have been installed.

NOTE:


Most instructions for reprogramming with C-III plus are displayed on the CONSULT
PC screen.



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
Figure A



After reprogramming is complete, you will be required to perform Idle Air Volume
Learn. The above condition are required for Idle Air Volume Learn to complete.

CAUTION:


Connect the GR8 to the 12V battery and select ECM Power Supply Mode.
If the vehicle battery voltage drops below 12.0V or rises 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.

B. Compare the P/N you wrote down to the numbers in the Current ECM Part Number
column in Table A below.


If there is a match, continue with the reprogramming procedure.



If there is not a match, reprogramming does not apply. Refer to ASIST for
further diagnostic and repair information.
