Straight-Ahead Position
WARNING: This page does not describe the selected car, but rather 37 other vehicles, including the 2006 BMW 330Ci, 2006 BMW 325Ci, 2005 BMW M3, 2005 BMW 330xi, and 2005 BMW 330i. However, it is still accessible from the selected car via links, so may be relevant.
The headlights are aligned with the vehicle's longitudinal axis and shine straight ahead
This position is assigned the angle 0°.
The straight-ahead position is defined by two angles:
- Angle to the zero-position sensor
- Angle to the mechanical reference point
The straight-ahead position is then calculated by the stepper motor controllers as follows:
- If the zero-position sensor is operational, the headlights are moved into the straight-ahead position from the position of the zero-position sensor.
- If the zero-position sensor has failed, the headlights are moved into the straight-ahead position from the mechanical stop. (The headlights move into the straight-ahead position during the calibration sequence when terminal 15 is ON.)
