The heated rear windshield and door mirrors are activated by pressing the switch on the climate control module (CCM) (3/112). The climate control module (CCM) transmits information via the controller area network (CAN) indicating the status of the electrical heating to the following:

• rear electronic module (REM) (4/58)
• driver door module (DDM) (3/126)
• passenger door module (PDM) (3/127).
