ACTION
1. Refer to step 6 in the SERVICE PROCEDURE to confirm this bulletin applies to the vehicle you are working
on.
2. If this bulletin applies, reprogram the ECM.

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.
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 retailer to determine if this
applies to your vehicle.

SERVICE PROCEDURE
ECM Reprogram
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.

NOTE:


Most instructions for reprogramming with CONSULT-III plus (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) Reprogramming" general procedure.

Preparation for Reprogramming


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 Throttle Valve Closed Position, Idle
Air Volume Learn, Accelerator Closed Position, and DTC erase.

CAUTION:


Connect a GR8 battery charger to the vehicle battery and set to 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.

3. Wait for the plus VI to be recognized / connected.


Serial number will display when the plus VI is recognized / connected.

4. Select Re/programming, Configuration.

Step 3: VI is
recognized

B. Compare the P/N you wrote down to the numbers in the Current ECM Part Number column in
Table A on page 5.


If there is a match, this bulletin applies. Continue with the reprogramming procedure.



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