Twilight Intensity, Value
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2009 Volvo S60, 2008 Volvo S60, 2007 Volvo S60, 2006 Volvo S60, and 2005 Volvo S60. However, it is still accessible from the selected car via links, so may be relevant.
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.
