Automotive self diagnosis

The legislation requires automatic headlamp level control for xenon lamps. This educational system contains an automatic-dynamic headlamp level control to stabilize changes in the headlamp level due to the body changing angles with the integrated acceleration/braking simulation (reversible).

The sensor inputs

• level signals of the front and rear axles and
• speed signal are detected.

This generates control signals for the actuator outputs

• headlamps' actuator and
• the malfunction indicator.

The system can self-diagnose over the K line: with a diagnostic adapter, all available measured value blocks can be displayed, and the functions

• coding
• default setting
• actuator diagnostics, and
• error logging

are executed.
