Circuit/System Description

WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.

The outside rearview mirror switch contains resistors which will reduce the signal voltage from the mirror control module, the mirror memory control module is programmed to move the driver outside mirror in a direction depending upon the voltage received from the outside rearview mirror switch. The outside rearview mirror switch has a 3 position rocker switch which corresponds to the driver outside rearview mirror select, no mirror select and passenger outside mirror selected. When the switch is in the no mirror select position and the mirror position switch is held in the DOWN position, mirror control module will command the driver outside mirror to fold or unfold and send a serial data message to the memory seat control module to send a fold or unfold command to the passenger window switch which will command the passenger outside rearview mirror to fold or unfold. The mirror control module and passenger window switch control the fold/unfold motors through bi-directional control circuits.
