ARMADA, TITAN AND TITAN XD;
SHIFT SHOCK, LACK OF POWER, AND/OR RPM FLUCTUATES
This bulletin has been amended to add Armada to the Applied Vehicles. No other changes have
been made. Please discard previous versions of this bulletin.

APPLIED VEHICLES:

2017 Armada (Y62)
2017 Titan (A61)
2016-2017 Titan XD (A61)

VK56VD (Gasoline V8)
APPLIED ENGINE:
APPLIED TRANSMISSION: 7AT - RE7R01B
IF YOU CONFIRM
One or more of the following, or the customer reports one or more of the following:


Transmission shift shock when accelerating enough to create a 7th gear to 3rd gear
down shift.



While driving at a steady speed, the engine RPM goes up and down (fluctuates) a
small amount.



With light acceleration at lower speeds there is a lack of power; feels like the
selected transmission gear is too high (may also be described as hesitation).

ACTION
1. Refer to step 6 in the SERVICE PROCEDURE to confirm ECM reprogramming applies.
2. Reprogram the ECM, if it applies.
3. Refer to step 22 in the SERVICE PROCEDURE to confirm TCM reprogramming
applies.
4. Reprogram the TCM, if it applies.

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
NOTE:


This procedure may require reprogramming of the ECM and TCM.



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.

IMPORTANT: Before starting, make sure:


ASIST on the CONSULT PC has been synchronized (updated) to the current
date.



All C-III plus software updates (if any) have been installed.



The CONSULT PC is connected to the internet (Wi-Fi, or cable).

ECM Reprogram

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

NOTE:


After ECM reprogramming is complete, you will be required to perform Throttle
Valve Closed Position, IAVL, and Accelerator Closed Position.



The above conditions are required for the IAVL to complete.

CAUTION:
 Connect the GR8 to the 12V battery and set to 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 plus VI. If Bluetooth® signal waves are
within range of the CONSULT PC during reprogramming, reprogramming may
be interrupted and the ECM may be damaged.

1. Connect the plus VI to the vehicle and open/start C-III plus.
2. Confirm the ignition is ON, with engine OFF.
3. Confirm the plus VI is recognized.


The Serial No. will display when the plus VI is recognized.

4. Select Re/programming, Configuration.

Step 3:
plus VI is
recognized

6. When you get to the screen shown in Figure 2, confirm ECM reprogramming 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).

xxxxxxxxxxx xxxxxx

6A: Current P/N

ENGINE
XXXXX -XXXXX

xxxxxxxxxxxxxx
xxxxxxxxxxx xxxxxx
xxxxxxxxxxxxxxxxxx

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, continue with the ECM reprogramming procedure.



If there is not a match, ECM reprogramming does not apply. Go to TCM
reprogram on page 11.

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.
 If more than one new P/N is available, 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.

Figure 3


Before reprogramming will start, you will be required to enter your User Name and
Password.
 The CONSULT PC must be connected to the Internet (Wi-Fi or cable).
 If you do not know your User Name and Password, contact your Service
Manager.
