Voluntary Service Campaign 2013 JX35 ECM Reprogram For Air Fuel Sensor (ITB12-067)

Check Air Fuel (A/F) Sensor Adjustment Values

1. Connect the CONSULT PC to the vehicle.
2. Turn the ignition ON.
3. Open ASIST on the CONSULT PC and start C-III plus.
4. Wait for the plus VI to be recognized / connected.
   • Serial number will display when the plus VI is recognized / connected.
5. Select Diagnosis (One System)  .
6. Select ENGINE  .
7. Select Data Monitor  .
8. Select A/F ADJ-B1  and A/F ADJ-B2  .
   • Use arrows to scroll and find the above items.
9. Select Start  .
10. Check values for A/F ADJ-B1 and A/F ADJ-B2  .
    • Value for each sensor should be between - 0.300  and 0.300  .
    • If a sensor (one or both) is out of the above specified range, make a note of it.
    • Sensor(s) that are out of the specified value will be replaced later  in this procedure.
    NOTE: Most vehicles serviced under this campaign will not  require new sensors. It is expected that only 5% of serviced vehicles will need sensor replacement.

    DO NOT replace A/F sensors at this time. 

    If needed, replace A/F sensors after  ECM reprogramming.

11. Go to ECM REPROGRAMMING below.

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

1. 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
   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 a 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  .
2. Return to the C-III plus home screen.
3. Confirm the VI is recognized / connected.
   • Serial number will display when the VI is recognized / connected.
4. Select Re/programming, Configuration  .
5. Follow the C-III plus on-screen instructions and navigate to the screen shown in Figure 4 down below.
   IMPORTANT: During the initial "Reprogramming Confirmation" set-up, if you get this screen (Figure 3):
   

   1. Select Delete  , then
   2. Select Other Operation  , then
   3. Continue with the reprogramming procedure.
   NOTE: If reprogramming does not complete, this screen can display for reprogramming recovery. Do not select Delete if this screen displays during reprogram recovery.
6. When you get to the screen shown in Figure 4, confirm this bulletin applies as follows:
   1. Find the ECM Part Number  and write it on the repair order.
      NOTE: This is the current  ECM Part Number (P/N).
   2. 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  , reprogramming does not apply  or it has already been done. Check Service Comm to confirm campaign eligibility.
   ECM PART NUMBER INFORMATION
   
   

   Model	Current ECM  Part Number: 23710 -
   2013 JX35	3JA1A, 3JA2A, 3JA3A, 3JA4A, 3JA5A, 3JA6A
   	3JA1B, 3JA2B, 3JA3B, 3JA4B, 3JA5B, 3JA6B

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.
     • In this case, the screen in Figure 5 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.
8. When the screen in Figure 6 displays, reprogramming is complete.
   NOTE: If the screen in Figure 6 does not  display (reprogramming does not  complete), refer to the information down below.
9. Disconnect the battery charger from the vehicle.
10. Select Next  .
    NOTE:

    • In the next steps down below, 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.

    ECM recovery: 

    Do not disconnect plus VI or shut down C-III plus if reprogramming does not complete. 

    If reprogramming does not complete and the "!?" icon displays as shown in Figure 7: 

    • Check battery voltage (12.0-15.5 V)
    • Ignition is ON, engine OFF
    • External Bluetooth® devices are OFF
    • All electrical loads are OFF
    • Select retry and follow the on screen instructions

Air Fuel (A/F) Sensor Replacement

1. If needed, replace A/F Sensor(s).
   1. Refer back to your notes from Check Air Fuel (A/F) Sensor Adjustment  .
      • If A/F ADJ-B1  value was out of specification, replace Bank 1 A/F sensor (bank 1 is toward the rear of the vehicle).
      • If A/F ADJ-B2  value is out of specification, replace Bank 2 A/F sensor (bank 2 is toward the front of the vehicle).
      NOTE: Replace A/F sensor(s) only if value was out of specification.
   2. Refer to the Service Manual for A/F Sensor replacement information.

For California owners

Dear Infiniti JX Owner:

Infiniti has discovered that your model year 2013 JX is equipped with an improper calibration that may in some situations illuminate a Malfunction Indicator Light (MIL). The cause is a calibration error which can improperly supply power to the downstream Air-Fuel (A/F) sensor heater circuit during engine off diagnostics. This has no effect on vehicle fuel consumption or safety. Drivability and performance may in rare circumstances be temporarily affected.

You should also be aware that if a MIL occurs and your vehicle is not repaired it will fail a Smog Check test in those areas of California where such testing is required under state law.

What Infiniti Will Do 

To correct this condition, Infiniti is conducting a Voluntary Service Campaign to reprogram the Engine Control Module (ECM) in your vehicle. Any affected A/F sensors will also be replaced. This free service should take about one hour to complete, but your Infiniti dealer may require your vehicle for a longer period of time based upon their work schedule.

To ensure the least inconvenience for you, it is important that you have an appointment before bringing your vehicle to the dealer for service. 

Your vehicle is eligible for this free service regardless of whether non-original parts were used for previous service and repairs, or if the service was performed by a repair facility other than a Infiniti dealer.

What You Should Do 

Contact your Infiniti dealer at your convenience in order to arrange an appointment to have your vehicle repaired. Please bring this notice with you when you keep your service appointment. Instructions have been sent to your Infiniti dealer.

If the retailer fails, or is unable to complete the modifications free of charge, you may contact the National Consumer Affairs Department, Infiniti Division, Nissan North America, Inc., P.O. Box 685003, Franklin, TN 37068-5003. The toll free number is 1-800-662-6200.

Thank you for your cooperation. We are indeed sorry for any inconvenience this may cause you.
