Main task

WARNING: This page is about a different car, the 2009 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

The task of the AHL control module is to regulate headlamp beam length. The control module ensures that the headlamps are always angled optimally during acceleration, braking and with different loads. The control system has two load angle sensors located at the front and rear axles, respectively.
