Circuit/System Description

WARNING: This page is about a different car, the 2008 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.

The automatic level control (ALC) position sensor provides a signal voltage between 0.5-4.85 volts to the ALC module. This signal voltage represents the wheel's position relative to the body. The ALC module provides a 5-volt reference and a low reference to the sensor.
