Electrical Function
The sun roof receives its main input signal from the sun roof switch. The switch has a two-way function and an automatic function. There are two ways to operate the sun roof. If the switch is held, the glass will move to the desired position. A brief press with the switch rearward opens the sun roof to the comfort position. A brief press with the switch forward closes the sun roof completely. Note that the automatic function can be used to move the glass panel from the tilted position to the comfort position. The automatic function cannot be used to close the glass panel from the tilted position.
When the sun roof is tilted, only continual operation is possible (except for automatic opening from the tilted to the completely open position).

The sun roof switch is connected to the Sun Roof Module (SRM) and the Sun Roof Module (SRM) is connected to the motor.
Input signals to the Sun Roof Module (SRM) are the vehicle communication cable (C cable (4)), battery voltage and the sun roof switch. Numbers 1 and 10 are for the motor's power supply, which goes through the Sun Roof Module (SRM). Sun roof feed (9) is the switch's signal voltage.
