VOLUNTARY EMISSIONS SERVICE CAMPAIGN
2018 SENTRA SR AND NISMO; ECM REPROGRAMMING
CAMPAIGN ID #:
APPLIED VEHICLES:
R1805
2018 Sentra SR (B17)
2018 Sentra Nismo (B17)
Check Service COMM or Dealer Business Systems (DBS)
National Service History to confirm campaign eligibility.
INTRODUCTION
Nissan is conducting this voluntary emissions service campaign on certain specific model
year 2018 Sentra Turbo SR and Sentra NISMO vehicles. The Engine Control Module
(ECM) will be reprogrammed so that in the event of an engine coolant bypass (Multiway
coolant flow Control Valve or MCV) diagnostic issue that properly illuminates a Malfunction
Indicator Light (MIL), the software can also accurately determine when the issue has been
corrected. This service will be performed at no charge to the customer for parts or labor.
IDENTIFICATION NUMBER
Nissan has assigned identification number R1805 to this campaign. This number must
appear on all communication and documentation of any nature dealing with this campaign.
DEALER RESPONSIBILITY
Dealers are to repair vehicles falling within range of this campaign that enter the service
department. This includes vehicles purchased from private parties, vehicles presented by
transient (tourists) owners, and vehicles in a dealer’s inventory.
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
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 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 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 VI. If Bluetooth® signal waves are
within range of the CONSULT PC during reprogramming, reprogramming may
be interrupted and the ECM may be damaged.

B. Compare the P/N you wrote down to the numbers in the Current ECM Part 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 is not needed or it has already been
done. Refer to Service COMM to confirm this campaign applies to the vehicle
you are working on.

9. 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.


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
