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

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
REPROGRAM THE ECM
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.

The CONSULT PC is connected to the Internet (Wi-Fi or cable).
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

After reprogramming is complete, you will be
required to perform Throttle Valve Closed
Position, Idle Air Volume Learn, Accelerator
Closed Position, and DTC erase. The above
conditions are required for the IAVL to complete.
Figure A
CAUTION:

Connect the GR8 to the 12V battery and select ECM Power Supply Mode.
If the vehicle battery voltage goes 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.
