2014 – 2017 VERSA NOTE;
POOR HEATER PERFORMANCE WITH
AMBIENT TEMPERATURE BELOW -20°C (-4°F)
This bulletin has been amended throughout. Discard previous versions of this bulletin.

2014 – 2017 Versa NOTE (E12)
APPLIED VEHICLE:
APPLIED VIN and DATE: 2014 – 2016: ALL
2017: Vehicles built before
3N1CE2CP(*)HL 351933 and October 25, 2016
IF YOU CONFIRM
The customer reports the HVAC system does not produce enough heat (poor heater
performance),
and
The issue occurs with ambient temperatures below -20°C (-4°F),
and
The engine thermostat is operating correctly.
ACTION
1. Install a heater thermostat per the SERVICE PROCEDURE in this bulletin.
2. Refer to step 6 in the Reprogram ECM section of the SERVICE PROCEDURE to
confirm reprogramming in needed.
NOTE: Reprogramming does not apply to 2016 and 2017 model year Versa NOTE.
3. Reprogram the ECM, if needed.
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.

Reprogram ECM
NOTE:


Reprogramming in this bulletin does not apply to 2016-2017 model year Versa
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
Figure A


After reprogramming is complete, you will be required to perform Idle Air Volume
Learn. The above condition are required for Idle Air Volume Learn to complete.

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 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.
