Offline SCN coding - AR54.21-P-0013-04X

The following work instructions describes the three different procedures for Offline SCN coding with the STAR DIAGNOSIS diagnosis system which is not networked:

1. Request coding data in paper format by fax 

   Requirements:

   • STAR DIAGNOSIS diagnosis system with printer and fax machine
   • Correct date and time setting in STAR DIAGNOSIS

     If special equipment is installed or removed from the vehicle, the SA codes must be redocumented in the vehicle documentation system (FDOK).

2. Request coding data on CD by fax, coding using SCN Repair CD 

   Requirements:

   • STAR DIAGNOSIS diagnosis system, PC with Internet connection and fax machine
   • Correct date and time setting in STAR DIAGNOSIS

     If special equipment is installed or removed from the vehicle, the SA codes must be redocumented in the vehicle documentation system (FDOK).

3. Determine coding data via "SDflash", "Office" variant on office PC 

   Coding via "SDflash", "Office" variant is not permissible for branches of the DaimlerChrysler Sales Organization Germany.

   Requirements:

   • "SDflash" software, "Office" variant with PC user rights
   • plus Intranet or Internet connection and CD writer
   • Printer for printing out the coding data or CD blank for preparing an SCN Repair CD

     If special equipment has been installed in or removed from the vehicle, the SA codes must be redocumented in the FDOK.

Entry into the coding in the diagnosis assistant system (DAS) 

1. Select menu item "control unit adaptations" or "initial startup". Continue with "F3".
2. Select the menu item "SCN coding" in the further program sequence. Continue with "F3".

   The program run may differ depending on the control unit.

3. Select menu item "Offline (STAR DIAGNOSIS not networked)". Continue with "F3".
4. Confirm note on sequence of SCN coding with "F2".
5. Select menu item "Determine vehicle data for Offline SCN coding from the vehicle". Continue with "F3".
6. Confirmation of the correct vehicle identification number with "F3".

A) Request coding data in paper form by fax: 

7. In the SCN coding main menu (in the DAS system) select the menu item "Offline (STAR DIAGNOSIS not networked)". Continue with "F3".
8. Confirm note on sequence of SCN coding with "F2".
9. Use "F4" to open the "Software Calibration Number" inquiry form.
10. Fill in the request form displayed.

    Fill in all fields marked with "*".

11. Print out the filled-in request form and transmit to the specified fax number.

    The answer fax is sent immediately with the SCN coding data.

12. Continue with "F3".
13. Select the menu item "Carry out SCN coding" and confirm using "F3".
14. Find the SCN coding data (Software Calibration Number (SCN), coding string and check digit 2) from the reply fax and enter them in the DAS screen.
15. Start the coding with "F3".

    Depending on the control module model the ignition must then be switched on and off again. To do this, follow the instructions in DAS.

16. Fill in missing data in the order protocol and then print out with "F11" and enclose with the repair order.

    The order log can also be stored in STAR DIAGNOSIS. After printing "F11" it is to be specified in the print dialog that printing to file should take place. This takes place by clicking on "print to file", selection of "printout of test step" and giving a file name. In Star Utilities using the program StarPad the order log can be displayed and printed out under the under the item "log" → "DAS log" → "printout of test step".

17. Continue with key "F2".

    The SCN coding is successfully concluded with the help of the coding data requested in paper form.

B) Request coding data on CD, coding by means of SCN Repair CD 

18. In the SCN coding main menu (in the DAS system) select the menu item "Offline (STAR DIAGNOSIS not networked)". Continue with "F3".
19. Confirm note on sequence of SCN coding with "F2".
20. Use "F5" to open the request form of SCN repair CD.
21. Fill in the request form displayed.

    Fill in all fields marked with "*".

22. Print out the filled-in request form and transmit to the specified fax number.

    The reply fax with the part number for the SCN Repair CD to be ordered is transmitted without delay.

23. Order the repair CD via the replacement parts ordering system (e.g. StarOrder) quoting the VIN.

    The SCN Repair-CD is sent.

24. In the menu "Offline (STAR DIAGNOSIS not networked)" select the menu item "Carry out SCN coding". Continue with "F3".
25. Insert the SCN Repair-CD in the CD-drive of STAR DIAGNOSIS. Continue with "F3".
26. Start the coding with "F3".

    Depending on the control module model the ignition must then be switched on and off again. To do this, follow the instructions in DAS.

27. Fill in missing data in the order protocol and then print out with "F11" and enclose with the repair order.

    The order log can also be stored in STAR DIAGNOSIS. After printing "F11" it is to be specified in the print dialog that printing to file should take place. This takes place by clicking on "print to file", selection of "printout of test step" and giving a file name.

    In Star Utilities using the program StarPad the order log can be displayed and printed out under the item "log" → "DAS log" → "printout of test step".

28. Continue with "F2".

    SCN coding is thus successfully concluded with the help of the requested SCN repair CD.

29. After successful coding, destroy the SCN Repair CD as per the guideline for theft-relevant parts (DRT 69/00).

    The irreparable damage should be documented on the repair order and on screen 2116 in the vehicle documentation system.

    C) Determine the coding data via "SDflash", "Office" variant on office PC 

    The coding via "SDflash", "Office" variant is not permissible for company-owned sales and service outlets of the DaimlerChrysler Sales Organization Germany.

    Two different methods can be used for carrying out SCN coding in the DAS:

    • Coding with printed-out coding data
    • Coding with an SCN Repair CD to be prepared
30. Print out vehicle data with "F11" in Diagnosis Assistance System.
31. Start "SDflash" program on office PC.
32. Enter vehicle identification number, select category, select control unit category ("engine control unit", "transmission control unit" or "other control unit") and confirm with "F2".
33. In the "coding" index enter the control unit part number, if available the control unit software numbers and the check digit 1.

    If special equipment has been installed in or removed from the vehicle, the SA codes must be entered in the fields provided for this in "SDflash":

    • "Positive SA codes": The SA codes entered here are included in the vehicle for the first time. They are taken into account for the generation of the SCN coding data
    • "Negative SA codes": The SA codes entered here have been currently removed from the vehicle. They are no longer taken into account for the generation of SCN coding data
34. Confirm entries in the "coding" index with "F3".
35. Confirm note concerning successful SCN generation and coding string formation.
36. Use "F11" to print out the coding string, SCN and check digit 2.

    With manual entry in Diagnosis Assistance System.

37. Insert CD blank in the CD hot space and burn the data on the CD.

    With electronic data take-over.

    Use "F7" to call up the CD burning program. Before using the burning program for the first time this must be set up. To do this, press "F6" (select burning program) and select the "*.exe-file" of the burning program.

    With the CD burning program change into the directory "C:\\userdata\\csd\\writefil\\create\\flashfil". Change from there into the category directory of the vehicle, then into the model series directory and after this into the vehicle identification number directory of the vehicle.

    Burn all files which are found in this directory onto the CD.

    So that no danger of mixing up exists for the CD, identify it as follows:

    • SCN Repair CD
    • VIN
    • control unit object number
    • Date
38. In the menu "Offline (STAR DIAGNOSIS not networked)" select the menu item "Carry out SCN coding". Continue with "F3".
39. 1. Enter SCN coding data (SCN, coding string and check digit 2). Continue with "F3".

    With manual entry in Diagnosis Assistance System.

    2. Insert prepared SCN repair CD in the STAR DIAGNOSIS CD drive. Continue with "F3".

       With electronic data take-over.

40. Start "F3" coding.

    Depending on the control module model the ignition must then be switched on and off again. To do this, follow the instructions in DAS.

    With manual coding of the control unit a control unit reset is carried out subsequent to the coding.

41. Use "F11" to print out the order log and enclose with the repair order.

    The order log can also be stored in STAR DIAGNOSIS. After printing "F11" it is to be specified in the print dialog that printing to file should take place. This takes place by clicking on "print to file", selection of "printout of test step" and giving a file name. In Star Utilities using the program StarPad the order log can be displayed and printed out under the item "log" → "DAS log" → "printout of test step".

42. Continue with "F2".

    SCN coding is thus successfully concluded with the shop-made SCN repair CD.

43. Destroy the SCN-Repair CD after successful coding, as per the guideline for theft-relevant parts (DRT 69/00). The destruction should then be documented on the repair order and on screen 2116 in FDOK.

    With electronic data take-over.
