Circuit/System Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2020 GMC Yukon XL, 2020 GMC Yukon, 2020 Chevrolet Tahoe, 2020 Chevrolet Suburban, and 2020 Cadillac Escalade ESV. However, it is still accessible from the selected car via links, so may be relevant.

The automatic level control system maintains a desired rear suspension position under all types of loading condition. The chassis control module determines the height of the vehicle based on the voltage from the suspension position sensors. The module supplies B+ to the vehicle level control compressor relay to raise and lower the vehicle in order to keep the vehicle level.
