2014-2015 Q50; MIL ON WITH DTC P0116
APPLIED VEHICLES:

2014-2015 Q50 (V37)
NOTE: This bulletin does not apply to Q50 Hybrid vehicles

IF YOU CONFIRM
The MIL is ON with P0116 Engine Coolant Temperature (ECT SENSOR) stored,
and
There are no drivability issues.

ACTION
1. Refer to step 6 in the SERVICE PROCEDURE to confirm if ECM reprogramming applies.
2. If it applies, reprogram the ECM.

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.
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 dealer to determine if this
applies to your vehicle.

SERVICE PROCEDURE
ECM Reprogramming



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
NOTE:
 After ECM reprogramming is complete, you will be required to perform Throttle Valve
Closed Position, Idle Air Volume Learn (IAVL), and Accelerator Closed Position.
 The above conditions are required for the IAVL to complete.

CAUTION:


Connect the GR8 battery charger to the vehicle battery.
The vehicle battery voltage must stay between 12.0V and 15.5V during reprogramming, or 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.

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.


The serial number (Serial No.) will display when the plus VI is recognized.

4. Select Re/programming, Configuration.

Step 3: 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).

6A: Current P/N

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, this bulletin applies. Continue with the reprogramming procedure.



If there is not a match, ECM reprogramming does not apply. Refer to ASIST for further diagnosis.



In some cases, more than one new P/N for reprogramming is available.
 If more than one new P/N is available, the screen in Figure 3 displays.
 Select and use the reprogramming option that does not have the message “Caution! Use ONLY
with ITBXX-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.
