And
There are no drivability issues.

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.
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
ECM REPROGRAMMING
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.

Figure A

CAUTION:


Connect a battery maintainer or smart charger set to reflash mode or a similar
setting. 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 plus VI. If Bluetooth® signal waves
are within range of the CONSULT PC and plus VI during reprogramming,
reprogramming may be interrupted and the ECM may be damaged.

NUMBER column in Table A below.


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



If there is not a match, reprogramming does not apply. Refer to ASIST for
further diagnosis.

7. Follow the on-screen instructions to navigate C-III plus and reprogram the ECM.
NOTE:
 In some cases, more than one new P/N for reprogramming is available.
 In this case, the screen in Figure 3 displays.
 Select and use the reprogramming option that does not have the message
“Caution! Use ONLY with NTBXX-XXX”.
 If you get this screen and it is blank (no reprogramming listed), it means there is no
reprogramming available for this vehicle. Close C-III plus and refer back to ASIST for
further diagnosis.
