Terrain Select Switch
WARNING: This page is about a different car, the 2014 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.
The terrain select switch is used to communicate driver commands of various vehicle control systems related to vehicle ride height, traction, and stability control. The switch includes an Auto setting and a Neutral setting. The switch communicates with the Cabin Compartment Node (CCN) via a LIN Bus. The CCN sends information related to the terrain select switch via the CAN Interior bus.
