Classification: AT12-009c Reference: Date: NTB12-103c March 31, 2016 CVT / TCM CALIBRATION DATA “WRITE” PROCEDURE This bulletin has been amended. The Applied Vehicles section has been revised and the Service Procedure has been updated. Please discard previous versions of this bulletin. APPLIED VEHICLES: 2013 – 2016 Altima Sedan (L33) 2013 – 2016 Pathfinder (R52) 2015 – 2016 Murano (Z52) 2015 – 2016 Quest (E52) 2014 – 2016 Rogue (T32) 2016 Maxima (A36) NOTE: Does not apply to Pathfinder or Murano 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 is replaced, or a CVT control valve (valve body) is replaced, or a Transmission Control Module (TCM) is replaced. NOTE: The following information may be helpful when performing the TCM Calibration Data “Write” Procedures: When starting the calibration “write” procedure in CONSULT-III (C-III) plus, and after selecting START under Work Support, the C-III plus screen may only blink. If this occurs, close ASIST (if open) and then select Start again. 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). 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. 1/19 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, 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 disk (provided with the new CVT or valve body). 2. Match the numbers on the disk with the new CVT or new valve body and QR label. See pages 3 and 4 for number matching examples. 2/19 NTB12-103c If a complete CVT is being replaced; match the following number (calibration file) Example Disc (CD) provided with the new CVT. Figure A Example QR label on the new CVT. Figure B Example Calibration file number on the CVT case or label. Skip two digits Figure C IMPORTANT: All three of the above numbers must be the same (they must match). 3/19 NTB12-103c If a new valve body is being replaced; match the following number (calibration file) Example Disc (CD) provided with the new valve body. Figure D Example QR label provided with the new valve body. Figure E Example Calibration file number on the valve body. Figure F IMPORTANT: All three of the above numbers must be the same (they must match). 4/19 NTB12-103c 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 VI and then open / start C-III plus. Make sure ASIST and other programs are closed. 6. After the plus VI to be recognized, select Diagnosis (All Systems). VI is recognized Step 6 Figure 1 7. Navigate C-III plus to TRANSMISSION > Work Support. 5/19 NTB12-103c 8. Select the scroll arrow shown 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). This screen print is used for warranty documentation. 10. Select scroll arrow shown Figure 3. Step 10 Screen print must show the VIN Example Print page 1 of 7 (1 / 7) Figure 3 6/19 NTB12-103c 11. Select WRITE IP CHARA – REPLACEMENT AT/CVT and then 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). 7/19 NTB12-103c 12. Select OK. Figure 5 13. Select My Computer.
