***** Retailer Announcement *****
Infiniti is conducting a retailer inventory service action to Update Electronic Control Module (ECM)
software on 1,874 specific 2017 QX80 vehicles identified in Service Comm. On the affected vehicles,
the ECM software is being updated to refine the MIL illumination logic for the exhaust gas temperature
sensor.
Affected vehicles are not subject to stop sale and are either currently in retailer inventory or assigned and
in transit to the retailer. Infiniti requests retailers complete this software update prior to sale to ensure
client satisfaction.
***** What Retailers Should Do *****
PLEASE FOLLOW THE ATTACHED REPAIR INSTRUCTIONS:
1. Verify if vehicles are affected by this client satisfaction initiative using Service Comm I.D. P6335
 New vehicles in retailer inventory can also be identified using DCS (Sales-> Vehicle Inventory,
and filter by Open Campaign).
 Refer to IPSB 15-286 for additional information
Please
continue to check newly arriving inventory for campaign applicability.

2. Use the attached procedure to install the updated software.
3. The service department should submit the applicable warranty claim for the action performed so it
can be closed on Service Comm and release the vehicle.
***** Retailer Responsibility *****
It is the retailer’s responsibility to check Service Comm using the appropriate campaign I.D for the
inspection status on each affected vehicle currently in new vehicle inventory. Infiniti requests retailers to
perform this repair on new vehicles in inventory prior to being retailed to ensure client satisfaction.
Thank you for your prompt attention to this matter.

ECM REPROGRAMMING

IMPORTANT: This reprogramming procedure has some steps in a different order than usual.
Make sure to follow all the steps in the specific order listed to properly complete the ECM
reprogramming.
Reprogramming Procedure


Vehicles Conditioning for ECM Reprogramming
 Engine coolant temperature: 70 – 100°C
(158 – 212°F)
 Battery voltage: More than 12.9V (At idle)
 Transmission: Warmed up

NOTE:


After reprogramming is complete, you will be required to perform DTC erase, Idle Air
Volume Learn (IAVL), and Throttle Valve Closed Position Accelerator Closed Position.



The above conditions are required for the IAVL to complete.

1. Connect the plus Vehicle Interface (plus VI) to the vehicle.


Make sure to use the correct VI for C-III plus (plus VI).
CAUTION: Make sure the plus VI is securly connected. If the plus VI connection is loose
during reprogramming, the process will be interrupted and the ECM may be damaged.

2. Connect the AC Adapter to the CONSULT PC.
CAUTION: 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.

3. Connect a battery charger to the vehicle battery:
For Conventional Vehicles


Set the battery charger at a low charge rate.
NOTE: The GR-8 (Battery and Electrical Diagnostic Station) set to “Power Supply” mode is
recommended.
CAUTION: Be sure the battery charger is connected securely to the battery. Make sure
the battery voltage stays between 12.0V and 15.5V during reprogramming. If the battery
voltage goes out of this range during reprogramming, the ECM may be damaged.

4. Turn off all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range of the
CONSULT PC and the VI.
CAUTION: Make sure to turn off all external Bluetooth® devices. If Bluetooth® signal
waves are within range of the CONSULT PC and the VI during reprogramming,
reprogramming may be interrupted and the ECM may be damaged.
5. Turn the ignition ON with the engine OFF or “not ready”.


The engine must not start or run during the reprogramming procedure.

6. Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC, blower, rear
defogger, audio, NAVI, seat heater, steering wheel heater, etc.
IMPORTANT: Make sure to turn OFF all vehicle electrical loads. Make sure the battery
voltage stays between 12.0V and 15.5V during reprogramming. If the battery voltage goes
out of this range during reprogramming, the ECM may be damaged.

7. Turn ON the CONSULT PC.

8. Select CONSULT-III plus (open C-III plus).

9. Wait for the plus VI to be recognized / connected.


Serial number will display when the plus VI is recognized / connected.
