Heated rear windshield and door mirrors
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).
For further information, see VIDA Design and Function, driver door module (DDM)/passenger door module (PDM) and Design and Function, rear electronic module (REM).
