Internal structure
The pivot angle is monitored by an inductive pickup
in the pivot module. The pickup value is evaluated
immediately in the relevant power module for
headlights as a pulse width-modulated signal.
If the motor or pickup does not function, the power
module sends an error message to the control unit
for headlight range control J431.
This is communicated to the driver in a display in
dash panel insert J285.
The same lamps that are used in the bi-xenon
headlight are also used in the adaptive light
headlight.
CAN Communication
The values marked with (*) are used as input
variables in calculating the pivot angle.
All other input variables are only needed for
dynamic headlight range control.
