RESETTING THE CONTROL UNIT MEMORY

After carrying out the test in reference, having disconnected the power supply, reset the movements memory as follows:

  • move the selector to maximum tilt position (end of anticlockwise rotation B3);
  • press the selector down vertically and hold in this position until the roof stops in maximum tilt position (the racks move back by about one centimetre once the maximum position is reached);
  • release the selector and depress the selector again within five seconds and hold down;
  • wait for the roof to complete its full travel, from maximum tilt to maximum slide - from maximum slide to closed;
  • release the selector, moving it to the roof closed position '0'.
The control unit memory is now reset.
