GF82.10-P-2112GV Component Description Of Headlamp Range Adjustment Control Unit
- with CODE (615) Bi-xenon headlamp unit with integrated curve illumination
- with CODE (616) Bi-xenon headlamp unit with integrated asymmetrical curve illumination

Component Identification:

Location
The headlamp range adjustment control unit is located below the front passenger seat.

Task
The headlamp range adjustment control unit has the following tasks:
^ Reading in of sensors, pickups and signals
^ Evaluation of input factors
^ Actuation of components

Reading in of sensors, pickups and signals
The input factors are read in via the following connections:
^ Direct line
^ Engine compartment CAN

Direct line
The signals from the following components are read via a direct line:
- Right front level sensor (B22/9) (on vehicles without code (489) AIRmatic (air suspension with level adjustment and adaptive damping system (ADS))
- Right rear level sensor (B22/10) (on vehicles without code (488) Steel/air suspension or code (489) AIRmatic (air suspension with level adjustment and adaptive damping system ADS))

Engine compartment CAN
The headlamp range adjustment control unit reads in the following information in order to control the headlamp range adjustment via the engine compartment CAN:
- Status of circuit 61
- Signal of the accelerator pedal sensor (B37)
- Wheel speeds and wheel rotation directions, brake signal, yaw rate and lateral acceleration
- Steering angle, steering angle rate of change, and turn signal status
- Status of circuit 56
- Diagnosis request
- Rear axle level (with code (488) Steel/air suspension)
- Vehicle level (with code (489) AIRmatic (air suspension with level adjustment and Adaptive Damping System ADS))

Evaluation of input factors
The input factors are evaluated by the microprocessor and the corresponding components are actuated.

Actuation of components
Components are actuated with the following line:
^ Serial communication interface

Serial interface
The following components are actuated via a serial interface:
- HRA power module (E1n3)
- HRA power module (E2n3)
