VOLUNTARY EMISSION RECALL CAMPAIGN
2016-2018 Q50 AND 2017 Q60; ENGINE CONTROL MODULE REPROGRAM
CAMPAIGN ID #:
R1726
APPLIED VEHICLES:
2016-2018 Q50 (V37)
2017 Q60 (CV37)
Check Service COMM or Dealer Business Systems (DBS)
National Service History to confirm campaign eligibility
INTRODUCTION
Infiniti is conducting this voluntary emission recall campaign on certain specific model year 2016-2018 Q50 and
2017 Q60 vehicles. The Engine Control Module (ECM) will be reprogrammed so that in the event of an
automatic transmission diagnostic issue, the diagnosis signals will be communicated properly and a Malfunction
Indicator Light (MIL) will be properly illuminated to notify the driver. This service will be performed at no charge
to the customer for parts or labor.
IDENTIFICATION NUMBER
Infiniti has assigned identification number R1726 to this campaign. This number must appear on all
communication and documentation of any nature dealing with this campaign.
DEALER RESPONSIBILITY
It is the dealer’s responsibility to check Service Comm or Dealer Business Systems (DBS) National Service
History for the campaign status on each vehicle falling within the range of this voluntary emissions recall which
for any reason enters the service department. This includes vehicles purchased from private parties or
presented by transient (tourist) owners and vehicles in a dealer’s inventory.
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 retailer to determine if this
applies to your vehicle.

IMPORTANT
Attention California Dealers:
California law prohibits owners from renewing their California registration if emissions related recall work has
not been performed. California dealers are now required to issue a proof of correction certificate to vehicle
owners upon completion of emission related recall work. Please fill out one of the campaign completion forms
for each owner that has this campaign performed. Instruct owners to keep this certificate unless they are
requested to mail it to the DMV. A sample of the form is shown below.
Figure A
In addition, an Emission Recall Campaign Completion Label must be filled out and attached to the underside of
the vehicle hood. A sample of the label is shown below.
NIS-UHL-16
Figure B
NOTE:

These forms (item number CAEMRC-5-13) and labels (item number NIS-UHL-16) are available from
Infiniti Publications (1-800-247-5321) at no charge.

When either item (form or label) is ordered, you will automatically receive the other item as well.

SERVICE PROCEDURE
ECM Reprogram
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.
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.
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

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 a GR8 battery charger to the vehicle battery and set to power supply mode. If the vehicle
battery voltage drops 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, continue with the reprogramming procedure.

If there is not a match, this campaign does not apply or it has already been done. Confirm this
campaign applies to this vehicle.
