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) module performs checks of internal calibration data. If a fault condition is detected, the ALC module will set the fault DTC, and may, depending upon the fault type, turn ON the SERVICE SUSPENSION SYSTEM message. Recovery from any controller fault condition is attempted only after the ignition is cycled ON and OFF.
