Classification: EC18-013 Reference: Date: NTB18-040 June 7, 2018 2017-2018 TITAN; AIR CONDITIONING BLOWS HOT AIR AFTER EXTENDED IDLING OVER 100°F APPLIED VEHICLES: APPLIED ENGINE: 2017-2018 Titan (A61) VK56VD (gasoline engine) NOTE: Does not apply to Titan XD IF YOU CONFIRM Hot air starts to blow from the dash vents while the Air Conditioning is ON, under the following conditions: After the engine has idled for an extended period with the vehicle in Drive (D-range). And Ambient temperature outside the vehicle is 100°F (37.8°C) or more. 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. 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. Nissan 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 Nissan dealer to determine if this applies to your vehicle. 1/10 SERVICE PROCEDURE ECM Reprogramming IMPORTANT: Before starting, make sure: ASIST on the CONSULT PC has been synchronized (updated) to the current date. All CONSULT-III plus (C-III plus) software updates (if any) have been installed. The CONSULT PC is connected to the Internet (Wi-Fi or cable). 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 B 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. 2/10 NTB18-040 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 Step 4 Figure 1 3/10 NTB18-040 5. Follow the on-screen instructions and navigate C-III plus to the screen shown in Figure 2. 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). xxxxxxxxxxxx Step 6A: Current ECM P/N xxxxx xxxxxxxxxxxxxxx xxxxxxxxxxxxxxx xxxxxxxxxxxxxxx Figure 2 B. Compare the P/N you wrote down to the numbers in the Current ECM Part Number column in Table A. If there is a match, continue with the reprogramming procedure. If there is not a match, close C-III plus and refer to ASIST for further diagnostic information. Table A MODEL Titan (Non-XD) YEAR 2017 2018 CURRENT ECM PART NUMBER: 23710EZ01A, EZ02A, EZ03A, EZ04A, EZ10A, EZ11A, EZ13A, EZ14A, EZ26A, EZ27A, EZ28A, EZ29A EZ01B, EZ02B, EZ03B, EZ04B, EZ10B, EZ11B, EZ13B, EZ14B, EZ26B, EZ27B, EZ28B, EZ29B EZ01C, EZ02C, EZ03C, EZ04C, EZ10C, EZ11C, EZ13C, EZ14C, EZ26C, EZ27C, EZ28C, EZ29C EZ10D, EZ11D, EZ13D, EZ14D EZ10E, EZ11E, EZ13E, EZ14E 9FT1B, 9FT2B, 9FT3B, 9FT4B 4/10 NTB18-040 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 NTBXX-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 Before reprogramming will start, you will be required to enter your User Name and Password. The CONSULT PC must be connected to the Internet (Wi-Fi or cable). If you do not know your User Name and Password, contact your Service Manager. Figure 4 5/10 NTB18-040 8. When the screen in Figure 5 displays, reprogramming is complete. NOTE: If the screen in Figure 5 does not display (indicating that reprogramming did 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 5 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 NTB18-040 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 6: 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 6 If reprogramming does not complete and the “X” icon displays as shown in Figure 7: 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 / VI cables are securely connected. All C-III plus updates are installed. Select Home, and restart the reprogram procedure from the beginning. Figure 7 7/10 NTB18-040 11. Follow the on-screen instructions to perform the following: Throttle Valve Closed Position Idle Air Volume Learn (IAVL) NOTE: Listed below are common conditions required for IAVL to complete. If IAVL does not complete within a few minutes, a condition may be out of range. Refer to the appropriate Electronic Service Manual (ESM) for specific conditions required for the vehicle you are working on. 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, rear window defogger) o Steering wheel: Neutral (Straight-ahead position) o Vehicle speed: Stopped o Transmission: Warmed up Accelerator Pedal Close Position Learning Erase DTCs Continue to the next page. 8/10 NTB18-040 12.
