EX AND FX; SHIFT RESPONSIVENESS ISSUES
This bulletin has been amended to change the first sentence of the IF YOU CONFIRM statement.
Discard and previous versions.

APPLIED VEHICLES: 2011 EX35 (J50)
2009 - 2011 FX35 (S51)
APPLIED ENGINE: VQ37VHR
APPLIED TRANSMISSION: 7 speed

IF YOU CONFIRM:
That the customer has experienced or is experiencing:
•

Harsher than expected down shifts when coasting to a stop

•

Hesitation/lag when accelerating after coasting

•

Hesitation/lag or harsher than expected down shifts when coming to a stop and accelerating again
(rolling stop)

•

Engine rev matching during moderate to heavy braking
NOTE: Engine rev matching is normal operation of the ASC (Adaptive Shift Control) in normal drive
mode and sport mode. The ECM and TCM reprogramming in this bulletin will remove engine rev
matching from ASC in normal drive mode, but it will remain as part of the ASC in sport mode.

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 and TCM.

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 (starting on page 2) 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 dealer to determine if this
applies to your vehicle.

SERVICE PROCEDURE
•

This procedure will require reprogramming of the ECM and TCM; which means most steps in this
procedure will need to be done twice.

•

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:
¾ Engine coolant temperature: 70 -100°C
(158 - 212°F)
¾ Battery voltage: More than 12.9V (At idle)
¾ Transmission: Warmed up
Figure A
NOTE:
•

After ECM reprogramming is complete, you will be required to perform Throttle Valve
Closed Position, Idle Air Volume Learn (IAVL), and Accelerator Closed Position.

•

The above conditions are required for the IAVL to complete.

CAUTION:
•

Connect a battery charger to the vehicle battery.
The vehicle battery voltage must stay between 12.0V and 15.5V during reprogramming, or the
ECM/TCM may be damaged.

•

Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the ECM/TCM 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/TCM 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/TCM may be damaged.

1. Connect the CONSULT PC to the vehicle to begin the reprogramming procedure.
2. Open ASIST on the CONSULT PC and start C-III plus.
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

5. Follow the C-III plus on-screen instructions and navigate to the screen shown in Figure 2 on the next page.

IMPORTANT:
During the initial “Reprogramming Confirmation” set-up, if you get the screen shown in Figure 1A:
1. Select Delete, then
2. Select Other Operation, then
3. Continue with the reprogramming procedure.
NOTE: If reprogramming does not complete, this screen can display for reprogramming recovery.
Do not select Delete if this screen displays during reprogram recovery.

6. When you get to the screen shown in Figure 2, confirm this bulletin applies as follows:
A. Find the ECM or TCM Part Number and write it on the repair order.
NOTE: This is the current ECM or TCM Part Number (P/N).

6A: Current P/N

Figure 2

B. Compare the P/Ns you wrote down to the numbers in the Current ECM Part Number column
in Table A on page 6, and Current TCM Part Number column in Table B, also on page 6.
•

If there is a match with one or both ECM and TCM P/Ns, this bulletin applies. Continue
with the reprogramming procedure.

•

If there is not a match with both ECM and TCM P/Ns, reprogramming does not apply.
¾ Both ECM and TCM P/Ns must be checked for a match.
¾ If there is a match with only one of the two (ECM or TCM), reprogram the one with
a matching number.

¾ In this case, the screen in Figure 3 displays.
¾ Select and use the reprogramming option that does not have the message “Caution! Use ONLY
with ITBXX-XXX”.

•

If you get this screen and it is blank (no reprogramming listed), it means there is no reprogramming
