2017 QX80; MIL IS ON WITH DTC P2080 AND/OR P2082
APPLIED VEHICLES:
2017 QX80 (Z62)
IF YOU CONFIRM:
The MIL is ON with DTC

P2080 (EXHAUST GAS TEMP SENSOR 1 B1),
And/or

P2082 (EXHAUST GAS TEMP SENSOR 1 B2).
ACTION:
1. Refer to step 6 in the SERVICE PROCEDURE to confirm this bulletin applies to the vehicle you are working
on.
2. If this bulletin applies, reprogram the ECM.
NOTE: If this bulletin does apply (the ECM needs to be reprogrammed), do NOT replace the exhaust gas
temp sensor.
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 retailer to determine if this
applies to your vehicle.

SERVICE PROCEDURE
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.

Take the vehicle for a 10 minute drive in order to meet the following Idle Air Volume Learn (IAVL)
conditions:
 Engine coolant temperature: 70 - 105°C
(158 - 221°F)
 Battery voltage: More than 12.9V (at idle)
 Transmission: Warmed up
Figure A
NOTE: After reprogramming is complete, you will be required to perform Throttle Valve Closed
Position, Idle Air Volume Learn, Accelerator Closed Position, and DTC erase. The above conditions are
required for IAVL to complete.
CAUTION:

Connect the GR8 to the 12V battery and set to ECM 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 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.

1. Connect the CONSULT PC to the vehicle to begin the reprogramming procedure.
2. Open / start C-III plus.
3. Wait for the plus VI to be recognized.

The Serial No. will display when the plus VI is recognized.
4. Select Re/programming, Configuration.
Step 3: plus
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).
xxxxxxxxxxxxxxxx
Step 6A:
Current ECM P/N

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, this bulletin applies. Continue with the reprogramming procedure.

If there is not a match, this bulletin does not apply. Close C-III plus and refer to ASIST for further
diagnostic information.

7. Follow the on-screen instructions to navigate C-III plus and reprogram the ECM.
NOTE:


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.

8. When the screen in Figure 4 displays, reprogramming is complete.
NOTE: If the screen in Figure 4 does not display (reprogramming does not complete), refer to ECM
recovery on the next page.
9. Disconnect the GR8 (battery charger) from the vehicle.
10. Select Next.
Step 10
Figure 4
NOTE:

In the next steps, (page 8), you will perform Throttle Valve Closed Position, Idle Air Volume Learn,
Accelerator Closed Position, and DTC erase.

These operations are required before C-III plus will provide the final reprogramming confirmation
report.
