Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Door Control Modules (2006-2007): Function: Short-Drop
During operation of the roof, all side windows lower at least 80 mm to prevent friction between the roof unit and the windows. A signal is transmitted from the Convertible Roof Module (CRM) via the CAN network to the Driver door module (DDM) and the Passenger door module (PDM). These send a signal on via LIN to the Left rear door module (LDM) and Right rear door module (RDM). When the door are opened the window lowers 4 mm to prevent wearing the roof's rubber weatherstrip. After the door has been closed the window goes up behind the rubber weatherstrip to prevent leakage.
