Initialisation
General
Since the position transmitters are integrated in the sunroof module, they do not have fixed allocation to the sunroof mechanism. In order to achieve this allocation, the module must register the mechanical settings and store them internally. This procedure is termed standardisation. Only the ”close” and ”lift” functions can be run with a sunroof that is not standardised.

For the anti-trapping protection, it is necessary for the module to register the mechanical resistance of the sunroof and learn a corresponding characteristic curve internally for the anti-trapping protection.

Initialisation of the sunroof comprises standardisation and learning of the characteristic curve for the anti-trapping protection.

Initialisation must be carried out:

•After replacing the sunroof module (sunroof drive motor)
•After replacing mechanical parts of the sunroof
•When the single-strike function is no longer possible

Standardisation
Set the sunroof in the ”lift” end position for standardisation purposes. On reaching this position, press and hold the switch in ”lift” for at least 15 seconds. Once this time has elapsed, the drive is activated until it blocks and then moves back a little. The position of the position transmitters is stored internally. The sunroof is standardised.

Anti-trapping protection characteristic curve
The following applies to series E38 to 9/98 and series E39 to 3/98:

Sunroof module with diagnosis index 20 (refer to diagnosis program identification)

The module automatically learns the characteristic curve during sunroof operation. The module recognises positions with mechanical stiffness and adapts the characteristic curve accordingly. Following initialisation, open and close the sunroof at least once by pressing the switch.

If the anti-trapping protection triggers in certain positions, the fault may be eliminated by passing over the corresponding position with the switch overshot.

The following applies to Series E39 from 3/98 and Series E53 (X5):

Sunroof module with diagnosis index 21 (refer to diagnosis program identification)

The following procedure is necessary in order to learn the characteristic curve:

•Carry out standardisation procedure (see Standardisation)
•Once the sunroof has been standardised (switching sound can be heard), briefly release the switch and, within 5 seconds, press and hold again in the ”lift” position.
•After approx. 15 seconds, the roof is lowered and assumes the ”open” position.
•After stopping briefly in the opened position the sunroof moves in the direction ”closed” and stops in the end position.
•The characteristic curve is now learned.

The switch must be held in the ”lift” position during the entire procedure.

Caution! The anti-trapping protection is not active during this procedure.
