ACTION
1. Refer to step 6 in the SERVICE PROCEDURE to confirm this bulletin applies to the
vehicle you are working on.
If this bulletin applies:
2. Reprogram the ECM.
3. Replace the Air Fuel Ratio (A/F) Sensor 1.
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

Reprogram the ECM

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) 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.

6. When you get to the screen shown in Figure 2, confirm this bulletin applies as follows.
A. Find the ECM Part Number and write it on the repair order.

NOTE: This is the current ECM Part Number (P/N).

6A: Current ECM P/N

Figure 2

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

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



If there is not a match, this bulletin does not apply. Close C-III plus and refer to
ASIST for further diagnostic information.

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.
IMPORTANT: If C-III plus locks up or freezes at this point or displays “cannot
complete reprogramming, CONSULT PC is set up with User Rights.
Reprogramming can be completed with Administrator log in”, the TOUGHBOOK
settings need to be changed so that Users have full access rights. See your
Dealership’s IT System Administrator for details.
