Suspension Vertical Accelerometers
WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
The suspension control module supplies a common 5 V reference and a ground circuit to each of the four corner vertical accelerometers. The accelerometers supply a signal of 0.3 - 4.7 V to the suspension control module.
