2013-2014 SENTRA;
INTERMITTENT ROUGH/LOW IDLE WHEN STOPPED
APPLIED VEHICLE: 2013-2014 Sentra (B17)

IF YOU CONFIRM:
The engine idle is rough when the A/C compressor engages or a sudden electrical load is
applied (such as operating a power window),
WHEN
The vehicle is stopped
AND
The transmission is in gear with the brakes applied.
NOTE: This incident does not occur when coming to a stop.

ACTION:
1. Compare the vehicle’s current ECM part number to those listed in Table A (see
page 5).
2. If the ECM part number matches one listed in Table A, reprogram the ECM.


If there is NOT an ECM part number match, this bulletin does not apply. Refer
to ASIST and the Electronic Service Manual (ESM) for further diagnosis.

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 Part Number Check / Reprogramming
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) 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
Figure A


After reprogramming is complete, you will be required to perform Throttle Valve
Closed Position, Idle Air Volume Learn, Accelerator Closed Position, and DTC
erase.

CAUTION:


Connect the GR8 to the vehicle 12 volt battery and set to ECM power supply
mode. If the vehicle battery voltage drops below 12.0V or rises above 13.5V
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 CONSULT PC to the vehicle to begin the reprogramming procedure.

2. Open C-III plus.

3. Wait for the plus VI to be recognized.


Serial number 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 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).

xxxxxxxxxxxxxx

6A: Current ECM P/N
xxxx
xxxxxxxxxxxxxx
xxxxxxxxxxxxxx

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, the ECM needs to be reprogrammed. Continue with the
reprogramming procedure.



If there is not a match, ECM reprogramming does not apply. Refer to ASIST and
the ESM 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.
