Classification: Reference: Date: EC15-018 ITB15-033 December 1, 2015 2015 QX80; MIL ON WITH DTC FOR A/F SENSOR APPLIED VEHICLE: 2015 QX80 (Z62) APPLIED ENGINE: VK56VD (V8) IF YOU CONFIRM: The MIL is ON with one or more of the following DTCs stored: Bank 1 P2096, P2097 – POST CAT FUEL TRIM SYS B1 P0130, P0131, P0132 – A/F SENSOR1 (B1) P0031, P0032 – A/F SEN1 HTR (B1) P014C, P014D, P015A, P015B – Air fuel ratio (A/F) sensor 1 (bank 1) Bank 2 P2098, P2099 – POST CAT FUEL TRIM SYS B2 P0150, P0151, P0152 – A/F SENSOR1 (B2) P0051, P0052 – A/F SEN1 HTR (B2) P014E, P014F, P015C, P015D – Air fuel ratio (A/F) sensor 1 (bank 2) ACTION: 1. Refer to step 6 in the SERVICE PROCEDURE to confirm ECM reprogramming applies. 2. If reprogramming applies, reprogram the ECM. 3. Replace only the A/F sensors related to the stored DTCs. If stored DTCs are for only one bank, replace only one A/F sensor for that bank. If stored DTCs are for both banks, replace both A/F sensors. NOTE: Do NOT replace both A/F sensors if the stored DTC(s) are for only one bank. 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. 1/11 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 -105°C (158 - 221°F) Battery voltage: More than 12.9V (At idle) Transmission: Warmed up FigureAA Figure 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/TCM may be damaged. Be sure to turn OFF all vehicle electrical loads. If a vehicle electrical load remains ON, the ECM/TCM 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/TCM 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/TCM may be damaged. 2/10 ITB15-033 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 Step 4 Figure 1 5. Follow the on-screen instructions and navigate C-III plus to the screen shown in Figure 2 on the next page. 3/10 ITB15-033 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 below. If there is a match, this bulletin applies. Continue with the reprogramming procedure. If there is not a match, ECM reprogramming does not apply. Go to Replace A/F Sensor on page 10. Table A CURRENT ECM PART NUMBER: 237105ZA0B, 5ZA1B, 5ZA2B, 5ZA3B 5ZB0B, 5ZB0C 5ZA0D, 5ZA1D, 5ZA2D, 5ZA3D 5ZA0C, 5ZA1C, 5ZA2C, 5ZA3C 4/10 ITB15-033 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 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. Figure 3 5/10 ITB15-033 8. When the screen in Figure 4 displays, reprogramming is complete. NOTE: If the screen in Figure 4 does not display (indicating that reprogramming did not complete), refer to the information on the next page. 9. Disconnect the 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. 6/10 ITB15-033 ECM recovery: Do not disconnect plus VI or shut down Consult III plus if reprogramming does not complete. If reprogramming does not complete and the “!?” icon displays as shown in Figure 5: 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. “Retry” may not go through on first attempt and can be selected more than once. Figure 5 If reprogramming does not complete and the “X” icon displays as shown in Figure 6: Check battery voltage (12.0 – 15.5 V). CONSULT A/C adapter is plugged in. Ignition is ON, engine OFF. Transmission is in Park. All C-III plus / plus VI cables are securely connected. All C-III plus updates are installed. Select Home, and restart the reprogram procedure from the beginning. Figure 6 7/10 ITB15-033 11. Follow the on-screen instructions to perform the following: Throttle Valve Closed Position. Idle Air Volume Learn (IAVL). NOTE: Listed below are the conditions required for IAVL to complete. If IAVL does not complete within a few minutes, a condition may be out of range. o Engine coolant temperature: 70 -105°C (158 - 221°F). o Battery voltage: More than 12.9V (At idle). o Selector lever: P or N. o Electric load switch: OFF (Air conditioner, headlamp, and rear window defogger). o Steering wheel: Neutral (Straight-ahead position). o Vehicle speed: Stopped. o Transmission: Warmed up (ATF TEMP SE less than 0.9V). Accelerator Pedal Close Position Learning. Erase DTCs. Continue to the next page. 8/10 ITB15-033 12. When the entire reprogramming process is complete, the screen in Figure 7 will display. 13. Verify the before and after part numbers are different. 14. Print a copy of this screen (Figure 7) and attach it to the repair order for warranty documentation. 15. Select Confirm. Step 13 Step 14 Step 15 Figure 7 16. Close C-III plus. 17. Turn the ignition OFF. 18. Disconnect the plus VI from the vehicle. Go to the next page. 9/10 ITB15-033 Replace A/F Sensor 1. Replace only the A/F sensor related to the stored DTCs. If stored DTCs are for only one bank, replace only one A/F sensor for that bank. If stored DTCs are for both banks, replace both A/F sensors. Refer to the Electronic Service Manual (ESM), section EM-Engine Mechanical, for replacement information. NOTE: Do NOT replace both A/F sensors if the stored DTC(s) are for only one bank. 2. Test drive the vehicle and make sure it operates correctly and the MIL is OFF. If the MIL comes ON, go back to ASIST for further diagnostic information. Diagnosis and repairs beyond the contents of this bulletin are not covered by this bulletin. 10/10 ITB15-033 PARTS INFORMATION DESCRIPTION PART NUMBER A/F Sensor 22693-1PM0A (Bank 1 and Bank 2) NOTE: Both banks use the same A/F sensor Part Number.
