Note! As the illustrations in this service information are used for different model years and/or models, some variation may occur. However, the
essential information in the illustrations is always correct.
Note! A rear view mirror with manual function cannot be replaced with automatic anti-dazzle or vice versa. The system will store diagnostic
trouble codes (DTCs). The upper electronic module (UEM) is integrated in the rear view mirror.
Note! Read off data from the control module before replacing the control module. Program this data back into the new control module.
Programmed data is read off via VIDA vehicle communication.
