Hazard Warning Switch: Description and Operation

Function
The hazard flasher switch (S6/1s1) is connected to the driver-side signal acquisition and actuation module (SAM) (N10/1) via a discrete line. When the hazard flasher switch (S6/1s1) is actuated, the corresponding input on the driver-side signal acquisition and actuation module (SAM) (N10/1) is connected to ground through the switch. The driver-side signal acquisition and actuation module (SAM) (N10/1) then actuates all turn signal lamps at a frequency of approx. 1.5 Hz. in addition the LED's for the hazard flasher indicator in the hazard flasher switch (S6/1s1) and the turn signal indicator lamps in the instrument cluster (A1) as well as the audible turn signal indicator are actuated by the driver-side signal acquisition and actuation module (SAM) (N10/1) via discrete lines.


NOTE: Hazard flashing is possible with the ignition/starter switch in any position.


Bulb failure is not recognized during the hazard flasher function!
