GF77.20-P-2004PP Opening Sliding Roof, Function

- with CODE (414) Power glass tilting/sliding roof
- up to Model Year 8

Function requirements:
- No overvoltage or undervoltage
- Terminal 15R ON
- Circuit 15 ON
- Overhead control panel control module (N70) recognizes non- actuated state before actuating switch (roof system switch (N70s1) not actuated for longer than t = 40 ms)

Function
The sliding roof is opened by pressing the roof system switch (N70s1) towards the rear. The overhead control panel control module (N70) reads in the status of the roof system switch (N70s1) and actuates the roof system motor (M12m1) as long as the roof system switch (N70s1) is actuated, however, max. only for t = 50 s (maximum activation time).

If the maximum activation time is exceeded, further actuation is only possible after the overhead control panel control module (N70) recognizes the non-actuated state of the roof system switch (N70s1).

Aborting the function
If the overhead control panel control module (N70) recognizes a lock- up, the "Open sliding roof" function is interrupted.

The "Open sliding roof" function is limited in the desynchronized state; actuation of the roof system motor (M12m1) is only possible briefly or maximum t = 1 s. Then the roof system switch (N70s1) must be released and reactuated before another actuation can take place.
