2020 GMC Acadia SLSECTION Position Sensors
WARNING: This page is about a different car, the 2021 GMC Acadia. However, it is still accessible from the selected car via links, so may be relevant.

The electronic suspension control (ESC) position sensors provide the ESC module with the body to wheel displacement input. The ESC module uses this and other inputs in order to control the stiffness of the shock absorber. If any body, or wheel motion is detected, the ESC module will determine how soft or firm each shock absorber should be to provide the best ride. The ESC position sensors are mounted at each front corner of the vehicle between the control arm and the body/frame.
