Please discard previous versions of this bulletin. APPLIED VEHICLES: 2013 - 2018 Altima Sedan (L33) 2019 Altima Sedan (L34) 2015 - 2017 Juke (F15) 2016 - 2018 Maxima (A36) 2015 - 2018 Murano (Z52) 2015 - 2019 NV200 (M20) 2013 - 2019 Pathfinder (R52) 2015 - 2017 Quest (E52) 2014 - 2019 Rogue (T32) 2017 - 2018 Rogue Sport (J11) 2017 - 2019 Sentra Turbo (B17) 2014 - 2017 Taxi 2019 Taxi NOTE: Does not apply to Pathfinder Hybrid, Murano Hybrid, or Rogue Hybrid. SERVICE INFORMATION The Service Procedure (starting on page 2) in this bulletin contains the steps to perform TCM Calibration Data "Write" Procedures. These procedures are used when a complete CVT assembly is replaced, a CVT control valve (valve body) is replaced, or a Transmission Control Module (TCM) is replaced. Refer to REPAIR OVERVIEW on page 2. This is a quick reference to determine which procedures need to be performed. 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. 1/20 REPAIR OVERVIEW PROCEDURE Erase/Write Calibration Data Save/Write Calibration Data G-Sensor Learning Clutch Point Learning Select Learning VALVE BODY REPLACEMENT Required TCM REPLACEMENT Not needed CVT ASSEMBLY REPLACEMENT Required Not needed Not needed Required Required Required (except for Juke vehicles) Required Not needed Not needed Not needed Required Required Required SERVICE PROCEDURE IMPORTANT: If replacing the TCM only, skip to page 14: SAVE / WRITE CALIBRATION DATA WHEN REPLACING THE TCM. ERASE / WRITE CALIBRATION DATA WHEN REPLACING CVT OR VALVE BODY NOTE: Use the following steps when a complete CVT assembly or valve body is replaced. Also use the following steps if the TCM was replaced with a complete CVT or valve body. Before starting, make sure: ASIST on the CONSULT PC has been freshly synchronized to the current date. All C-III plus software updates (if any) have been installed. 1. Obtain the calibration file disc (provided with the new CVT or valve body). 2. Match the numbers on the disc with the new CVT or new valve body and QR label. See pages 3 and 4 for number matching examples. 2/20 NTB12-103f If a complete CVT is being replaced, match the following number (calibration file): Disc (CD) provided with the new CVT. Example QR label on the new CVT. Figure A Example Calibration file number on the CVT case or label. Figure B Example Skip two digits Figure C IMPORTANT: All three of the above numbers must be the same (they must match). 3/20 NTB12-103f If a new valve body is being replaced, match the following number (calibration file): Example Disc (CD) provided with the new valve body. QR label provided with the new valve body. Figure D Example Calibration file number on the valve body. Figure E Example Figure F IMPORTANT: All three of the above numbers must be the same (they must match). 4/20 NTB12-103f 3. Connect the external disk drive to the CONSULT PC. NOTE: Use the external disk drive provided with the C-III plus kit. 4. Load the CD into the external disc drive. 5. Connect the CONSULT PC to the vehicle with the plus VI and then open / start C-III plus. Make sure ASIST and other programs are closed. 6. After the plus VI is recognized, select Diagnosis (All Systems). Step 6: plus VI is recognized Step 6 Figure 1 7. Navigate C-III plus to TRANSMISSION > Work Support. 5/20 NTB12-103f 8. Select the scroll arrow shown in Figure 2. Step 8 Figure 2 9. Print a copy of the screen shown in Figure 3 and attach it to the repair order. NOTE: Make sure to print page 1 of 7 (1 / 7).

Select WRITE IP CHARA � REPLACEMENT AT/CVT, and then select Start. Step 11 Figure 4 IMPORTANT: When starting the calibration "write" procedure in C-III plus, and after selecting Start under Work Support, the C-III screen may only blink. If this occurs, confirm ASIST is closed and then perform step 11 above. If there is still no change: reboot the CONSULT PC, keep ASIST closed, and restart this procedure from step 1. If error "STOPPED, no comm. with ECU" shows when trying to write calibration data, verify that the vehicle is in park (P). 7/20 NTB12-103f 12. Select OK. Step 12 13. Select My Computer.
