Programming the control module

Programming the control module

Points to remember while programming

Pay attention to the following points before programming:


• The car must be standing on a level surface

• The soft top mechanism must be correctly adjusted mechanically. The mechanical adjustment of the soft top directly affects the possibility of programming the potentiometer values correctly. Therefore, it is very important that the soft top mechanism has been correctly adjusted mechanically before programming commences. In particular, the soft top stop position must be correct. Otherwise, the programming will definitely be incorrect. It is also equally important to program the new potentiometer values after major mechanical adjustments of the soft top mechanism.

• Waking the control module. When the control module is inactive for more than three seconds, it will go into a state of rest. It must then be "woken up" before it is possible to establish contact between the diagnostic tool and the control module. See .

• Lower the rear seat backrest. While programming is being performed, it is possible that the rear window will come into contact with the head restraint on the rear seat backrest. To avoid damaging the rear window, resulting in the need to replace the roof cloth, all programming must be performed with the backrest in its lowered position.

• Operating the soft top while programming. Note the differences in operating the soft top with the diagnostic tool and with the ROOF button in the centre console: With the ROOF button, the soft top will take up its programmed position but with the diagnostic tool, it will operate until it reaches its mechanical stop. The diagnostic tool must be used to operate the soft top mechanism while programming is being performed unless stated otherwise. While operating the soft top, keep the motor activated for a further five seconds after the end position has been reached. This is to ensure that the mechanical end positions have been reached.


Programming

The battery must be in good condition while programming is being carried out.

Important

The soft top mechanism must be operated from the diagnostic tool while programming is being carried out. The motors must be kept activated for five seconds after the end position has been reaches. This is to ensure that the mechanical end positions have been reached.


The soft top must be raised completely (closed), the latch handles in the first bow closed and the fifth bow locked to the soft top cover.

Make a copy of the table. See . Note on the copy the values that are read while programming.


1. Fold forward the rear seat backrest.

Important

The backrest must be lowered. Otherwise, the rear window may be damaged against the head restraints while programming is in progress.


2. Open the latch handles securing the soft top to the windscreen frame.

3. Connect the diagnostic tool to the data link connector. The ignition must be in position "OFF".

4. Step forward to "TSAS" on the diagnostic tool.

5. Turn the ignition to the "ON" position.

6. Press a window lift button so that it is lowered automatically and immediately press ENTER on the diagnostic tool. As the latch fittings are open, the control module will be prevented from going into a state of rest.

7. Read "SOFTWARE VERSION" under the "SYSTEM INFORMATION" menu. If the response is lower than 4.02, the car must be rectified in accordance with SI 812-1570. If the response is 4.02 or higher, continue with step 8.

8. Select "Tonneau Motor, Down" under the "Activate" menu and completely lower the soft top cover. Allow the motor to run for a further five seconds after the end position has been reached. This is to ensure that the mechanical end positions have been reached.

9. Select "#5 bow Motor, Down" under the "Activate" menu. Allow the motor to run for a further five seconds after the end position has been reached. This is to ensure that the mechanical end positions have been reached.

10. Select "5 Bow Latch Motor, Down" under the "Activate" menu to lock the fifth bow. Allow the motor to run for a further five seconds after the end position has been reached. This is to ensure that the mechanical end positions have been reached.

11. Read value "5TH Bow Potentiometer Position" under the "Read Values" menu for a reading of the fifth bow low limit. Note the value on row L in the table.

12. Select "5 Bow Latch Motor, Up" under the "Activate" menu to open the fifth bow latch.

13. Select "#5 bow Motor, Up" under the "Activate" menu and operate the fifth bow to its raised position. Allow the motor to run for a further five seconds after the end position has been reached. This is to ensure that the mechanical end positions have been reached.

14. Read value "5TH Bow Potentiometer Position" under the "Read Values" menu for a reading of the fifth bow high limit. Note the value on row I in the table. See .

15. Select "Tonneau Motor, Down" under the "Activate" menu and completely lower the soft top cover. Allow the motor to run for a further five seconds after the end position has been reached. This is to ensure that the mechanical end positions have been reached.

16. Read value "Tonneau Potentiometer Position" under the "Read Values" menu to take a reading of the soft top cover low limit. Note the value on row H in the table. See .

17. Select "Tonneau Motor, Up" under the "Activate" menu and completely raise the soft top cover. Allow the motor to run for a further five seconds after the end position has been reached. This is to ensure that the mechanical end positions have been reached.

18. Read value "Tonneau Potentiometer Position" under the "Read Values" menu to take a reading of the soft top cover high limit. Note the value on row E in the table. See .

19. Select "Main Motor, Up" under the "Activate" menu and operate the soft top to its completely raised (closed) position. Allow the motor to run for a further five seconds after the end position has been reached. This is to ensure that the mechanical end positions have been reached.

20. Read value "Main Potentiometer Position" under the "Read Values" menu to take a reading of the soft top high limit. Note the value on row A in the table. See .

21. Select "Main Motor, Down" under the "Activate" menu and operate the soft top to its completely lowered (open) position. Allow the motor to run for a further five seconds after the end position has been reached. This is to ensure that the mechanical end positions have been reached.

22. Read value "Main Potentiometer Position" under the "Read Values" menu to take a reading of the soft top low limit. Note the value on row D in the table. See .

23. Calculate the new potentiometer values for the high and low limits using the table. See .

Only the soft top and fifth bow overlap positions are calculated below. The soft top cover overlap position is fixed and does not need to be calculated.

24. Read value "Main Potentiometer Position" under the "Read Values" menu.

25. Operate the soft top with the ROOF button so that the distance between the edge of the first bow and the middle of the front edge of the boot lid is 110 cm. Have an assistant help you and make sure the soft top does not move.

26. Read value "Main Potentiometer Position" and note the value on row B in the table. See .

The reading corresponds to the high main motor overlap value ("MAIN MOTOR, OVERLAP HIGH LIMIT").

27. The low main motor overlap value is calculated by deducting six units from the high overlap value ("OVERLAP HIGH LIMIT" - 6 = "OVERLAP LOW LIMIT"). See row C in the table .

28. Adjust the soft top cover overlap positions as described below on cars with VIN S7000216 - S7013202 that DO NOT have box B5 marked on the modification identity plate.

Fixed positions can be used on other cars. See . Continue with step 6.

28.a. Step forward to "Tonneau Potentiometer Position" under the "Read Values" menu on the diagnostic tool.

28.b. Continue to raise (close) the soft top with the ROOF button so that the distance between the front of the soft top cover and the back of the cross member behind the rear seat backrest is 26 cm.

28.c. Read value "Tonneau Potentiometer Position" under the "Read Values" menu and note the value on row F in the table. See .

The reading corresponds to the high soft top cover overlap value ("TONNEAU MOTOR, OVERLAP HIGH LIMIT").

28.d. Operate the soft top with the ROOF button so that the distance between the front of the soft top cover and the back of the cross member behind the rear seat backrest is 20 cm.

28.e. Read value "Tonneau Potentiometer Position" and note the value on row G in the table. See .

The reading corresponds to the low soft top cover overlap value ("TONNEAU MOTOR, OVERLAP LOW LIMIT").

29. Select "5TH Bow Potentiometer Position" under the "Read Values" menu.

30. Completely raise (close) the soft top with the ROOF button. Continue to operated the soft top mechanism with the ROOF button until the soft top cover has closed and the fifth bow is lowered so that the distance between the edge of the fifth bow cloth tongue and the middle of the front edge of the boot lid is 30 cm.

31. Read value "5TH Bow Potentiometer Position". Note the value on row K in the table. See . The reading corresponds to the low fifth bow overlap value ("#5 BOW MOTOR, OVERLAP LOW LIMIT").

32. The high fifth bow overlap value is calculated by adding eight units to the low overlap value ("OVERLAP LOW LIMIT" + 8 = OVERLAP HIGH LIMIT"). See row J in the table. See .

33. Program the TSAS control module with the new values by selecting “PROGRAM POTENTIOMETERS” under the F2 menu.

First, the programmed main potentiometer values are displayed.

33.A. Press “CHANGE VALUE”.

Check


1. Clear DTCs.

2. Terminate communication between the diagnostic tool and TSAS.

3. Operate the soft top mechanism up and down for a few cycles with the ROOF button.

4. Connect the diagnostic tool and check all the potentiometer values by comparing the programmed values under the "Programming" menu with the values calculated in the table. See .

5. Terminate communication if all the values are correct.

6. If any of the values are incorrect, the correct value from the table must be programmed. Then return to step 2 above and continue from there.
