Roof Hatch
WARNING: This page is about a different car, the 2010 Volvo V70, 2009 Volvo V70, and 2008 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
The sunroof is equipped with a sunroof module (SRM) (4/33) that handles its functions. The sunroof is operated via a switch on the roof panel.
The Central electronic module (CEM) (4/56) transmits information about the vehicle's speed to the Sun roof module (SRM). This information is used to calculate how much force is required from the motors to operate the sun roof. The Sun roof module (SRM) also receives signals from the Central electronic module (CEM), via a directly connected cable, whether to carry out a "comfort open" or "comfort close" or to carry out a sun roof initialization.
