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.

HINT  : 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 then restart this procedure from step  6 on page 5.
  • If the error "STOPPED, no comm. with ECU" shows when trying to write calibration data, verify that the vehicle is in park (P).

SERVICE PROCEDURE

ERASE/WRITE CALIBRATION DATA WHEN REPLACING CVT OR VALVE BODY

HINT: 

• Use the following steps when a CVT assembly or valve body is replaced.
• Also use the following steps if the TCM was replaced with  a CVT assembly 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  on page 21.
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.
   • 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).
   • 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 open/start C-III plus.
   • Make sure ASIST and other programs are closed.
6. After the VI is recognized, select Diagnosis (All Systems).

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 then restart this procedure from step  1.
      • If the error "STOPPED, no comm. with ECU" shows 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 on page 2 (see Figures on pages 3 and 4).
    • The numbers must  match.
17. Select Next. 

    HINT:  If the error "STOPPED, no Comm with ECU" is displayed, confirm that the vehicle is in Park.

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