Twilight intensity, value

Measurement range: 0 - 15

The climate control module (CCM) calculates the twilight intensity based on the signal from the twilight sensor.

This value is transmitted to the central electronic module (CEM) via the control area network (CAN) to regulate the luminance of the buttons and combined instrument panel (DIM).

The value increases with increased and falls with diminished light intensity. The luminance of the buttons and combined instrument panel (DIM) will increase with increasing light intensity and fall with diminishing light intensity.
