Sunroof Control Module Programming and Setup
When replacing the sunroof motor/control module, the sunroof
motor/actuator initialisation/teach procedure must be followed.
Initialisation and Learn Procedures
In order for the sunroof system to perform correctly it needs to
establish its position and the force profile it will encounter
under normal closing conditions. These two procedures need to be
run when a new controller is placed on a vehicle, when a service
procedure is performed on any mechanical component, or if the
system seems to lose track of its known position.
Initialisation and Reinitialisation
When the sunroof controller is not initialised it will perform
all OPEN requests, but no express CLOSE or LIN-Bus communicated
close commands. It will only perform a CLOSE operation requested by
the switch with obstacle detection disabled. If an initialisation
procedure is interrupted the controllers will return to the not
initialised state. Which procedure is run depends on the state of
the controller.
For a module which is not initialised begin the process by
holding the sunroof switch in the CLOSE position. The sunroof will
move to the end of physical travel in the closed direction and
store that position. During this time it is necessary to keep the
switch active until the process completes. At the completion of the
procedure the sunroof should back off slightly to its soft stops.
The rest of the defined positions are determined by offsets from
this home position.
For a module which has been previously initialised release the
switch after the sunroof is considered fully closed by the
software. Then hold the sunroof switch in the closed position for
10 s. The sunroof shall resume motion in the CLOSE direction
until the end of travel is detected. During this time it is
necessary to keep the switch active until the process completes. At
the completion of the procedure the sunroof should back off
slightly to its soft stops.
For learning the force profile for anti-pinch algorithm after
initialisation or re-initialisation move the roof to the fully open
position and release the switch. Activate the OPEN function of the
switch continuously for more than 15 s. At this point, the
sunroof will automatically begin to move to the fully closed
position. During this time it is necessary to keep the switch
active until the process completes.
