Circuit Description
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
The air suspension sensor provides a signal voltage between 0.3-4.7 volts to the air suspension module. This signal voltage represents the wheels position relative to the body. The air suspension module provides a 5-volt reference and a low reference to the sensor.
