Daytime Running Lights (From Structure Week 201044, Option)
Daytime running lights (10/56-57) are activated via an extra "auto-position" in Light switch module (LSM) (3/111). Daytime running lights can also, on certain markets, be activated via position 0 and P (parking lights).
When "auto-position" is selected in Light switch module (LSM) the Central electronic module (CEM) (4/56) uses information from the vehicle's twilight sensor (7/12) for automatic switching between low beams and daytime running lights. In case of missing or incorrect signal from the twilight sensor the low beams are used as usual.
Daytime running lights are never active together with running lights. On vehicles equipped with ABL-lights, there is a diode by the "auto-position". This diode pertains to the ABL-lights' function and not the daytime running lights.
For certain markets, when Light switch module (LSM) is et in "position P", the daytime running lights are deactivated automatically and the parking lights are turned when the automatic transmission's gear selector changes to P- or N-position, or when the parking brake is activated.
The light switch module (LSM) is directly connected to the central electronic module (CEM). Power is supplied to the daytime running lights, via a directly connected relay (2/152), from the central electronic module (CEM).
