Circuit/System Description

WARNING: This page is about a different car, the 2009 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

The driver door module (DDM) and front passenger door module (PDM) each contain switches that control power door lock and window functions. The DDM also contains the control switch for the power outside rear view mirrors. These switches are integrated within the door control modules and are not serviceable as separate components. The DDM and PDM monitor these switch inputs for internal faults and will set B1023 00 if any are detected.
