Control Units
Car Access System 4
The Car Access System 4 issues the enable signal for the slide/tilt sunroof.
"Terminal 50 ON" status is sent via K-CAN2 while starting the engine. The roof control module prevents activation of the motors for the slide/tilt sunroof or interrupts current operation. This means that there is more energy available from the battery for the starter to start the engine.
Footwell module
The footwell module makes available the status of the door contacts and the driver's door lock barrel.
The footwell module also supplies the roof control module with information concerning the "Terminal 58g ON" status.
Roof control module
The roof control module contains the complete functions of the slide/tilt sunroof. The roof control module is always installed in connection with the slide/tilt sunroof.
The relays required to drive the slide/tilt sunroof motors are integrated in the roof control module.
Slide/tilt Sunroof Motors
One motor for the slide/tilt sunroof has two Hall sensors.
The Hall sensors are located on the motor shaft and are offset against one another by 90º.
When the motor is running, this results in two temporally offset Hall signals that are used to register the direction of rotation of the motor and for the anti-trapping protection function.
NOTE: Two motors are fitted to move the slide/. tilt sunroof.
