HEADLAMP — Headlamp Aiming Control — Description
EL-49wiring diagramPure-mechanical position servo — no electronics. Sensor disc + brush set is the position-feedback element. Failure modes: stuck or dirty brushes on sensor disc cause one position to be skipped; failed UP/DOWN coil leaves the actuator able to move in only one direction.
Description
NOTE
• The vertical direction of the headlamp projection can be adjusted from inside the vehicle to prevent the headlamp beam axis from facing upward due to a change in the number of occupants and load conditions in the vehicle.

NOTE
How it works: the dashboard aiming switch (positions 0/1/2/3) commands a target. Each aiming motor unit has a rotating sensor disc with conductive (continuity) and insulated (no-continuity) sectors A/B/C/D. The motor (UP coil + DOWN coil) drives the disc until the brush pattern on the sensor matches the switch demand, then the motor stops — a simple closed-loop position servo.
