SERVICE PROCEDURE

ERASE/WRITE CALIBRATION DATA WHEN REPLACING CVT OR VALVE BODY

HINT: 

• 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)  .
   • If a calibration file disc is available, continue to step 2, below.
   • If a calibration file disc is not available or was damaged, skip to OBTAINING A CALIBRATION FILE WHEN CD IS UNAVAILABLE  below.
2. Match the numbers on the disc with the new CVT or new valve body and QR label.
   • See below for number matching examples.

   If a complete CVT is being replaced, match the following number (calibration file): 

   • Disc (CD) provided with the new CVT.
   • QR label on the new CVT is located on the Transmission range switch.
   • Calibration file number on the CVT case or label.
   IMPORTANT: All three (3) of the above numbers must be the same (they must match).

   If a new valve body is being replaced, match the following number (calibration file): 

   • Disc (CD) provided with the new valve body.
   • QR label provided with the new valve body.
   • Calibration file number on the valve body.
   IMPORTANT: All three (3) of the above numbers must be the same (they must match).
3. Connect the external disk drive to the CONSULT PC.

   HINT:  Use the external disk drive provided with the C-III plus kit.

4. Load the CD into the external disk drive.
5. Connect the CONSULT PC to the vehicle with the VI, and then start C-III plus.
   • Make sure ASIST and other programs are closed.
6. After the VI is recognized, select Diagnosis (All Systems)  .
7. Navigate C-III plus to TRANSMISSION > Work Support  .

   • This screen print is used for warranty documentation.
10. Select the scroll arrow shown in Figure 9 and select the Work support  tab as shown in Figure 10 below.
11. Select WRITE IP CHARA - REPLACEMENT AT/CVT  , and then select Start  .
    IMPORTANT: When starting the calibration "write" procedure in C-III plus, and after selecting Start  under Work support  , the C-III plus 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 the error "STOPPED, no comm. with ECU" displays when trying to write calibration data, verify that the vehicle is in park (P).
12. Select OK  .
13. Select My Computer  .
14. Locate the calibration file.

15. Highlight the file, and then select Open  .
16. Verify that the Serial No.  (calibration file number) shown matches the numbers from step  2 above (see Figures above).
    • The numbers must  match.
17. Select Next  .

    HINT:  If the error "STOPPED, no comm. with ECU" displays when trying to write calibration data, verify that the vehicle is in park (P).

18. Before  selecting Start  , follow the directions in Figure 16.

25. Clear any DTCs that may have set.

    HINT:  Any DTCs that will not clear are not covered by this bulletin. Refer to the appropriate Electronic Service Manual (ESM) for further diagnostic information.

26. If the valve body  was replaced, perform CLUTCH POINT LEARNING  under "Transmission Work Support" in C-III plus.
    • Follow the steps for CLUTCH POINT LEARNING  exactly as presented in C-III plus.
    • If the procedure is not performed correctly, the vehicle may not move when the CVT is placed in gear.
      • If this condition occurs, cycle the ignition OFF/ON, and then perform CLUTCH POINT LEARNING  again.
27. If the CVT assembly  was replaced, do not  perform CLUTCH POINT LEARNING  .
28. Perform Select Learning (Drive/Reverse Learning)  .
    1. Set the parking brake.
    2. Start the engine, and then wait 5 seconds.
