*****Dealer Announcement*****
Nissan is conducting a quality action to update the Engine Control Module (ECM) software to
prevent permanent storage of a DTC as a result of a Multiway Control Valve (MCV)
malfunction on 1,013 specific 2018 Nissan Sentra (B17) SR and NISMO vehicles equipped
with the MR16DDT engine.
If a MCV malfunction occurred and was repaired, the current ECM logic will allow a
technician to reset the Malfunction Indicator Lamp (MIL), but the DTC will remain stored in
ECM memory. Resulting in Inspection/Maintenance (I/M; a.k.a. smog test) failure when a
DTC check is performed at an inspection station.
Affected vehicles are not subject to stop sale and are either currently in dealer inventory or
assigned and in transit to the dealer. In the interest of customer satisfaction, Nissan
requests dealers to update the ECM software on the affected vehicles prior to retail sale.
*****What Dealers Should Do*****
1. Verify if vehicles currently in new dealer inventory are affected by this quality action
using Service Comm or DBS National Service History – Open Campaign I.D. P8307
 New vehicles in dealer inventory can also be identified using DBS
(Sales-> Vehicle Inventory, and filter by Open Campaign).
 Refer to NPSB 15-460 for additional information
 Please continue to check newly arriving inventory for campaign
applicability.
2. Use the attached procedure to remedy vehicles affected by this quality action.
3. The service department should submit the applicable warranty claim for the action(s)
performed so it can be closed on Service Comm and release the vehicle.
***** Dealer Responsibility *****
It is the dealer’s responsibility to check Service Comm or DBS National Service History Open Campaign using the appropriate campaign I.D for the inspection status on each
affected vehicle currently in new vehicle inventory. Nissan requests dealers to perform this
repair on new vehicles in inventory prior to being retailed to help ensure customer
satisfaction.

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.

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.
