Switch, Terrain Select: Operation
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 Body Control Module (BCM). The BCM sends information related to the terrain select switch via the CAN Interior bus. Some modules that use the information from the terrain select switch are as follows:
- Air Suspension Control Module (ASCM)
- Antilock Brake Module (ABS)
- Powertrain Control Module (PCM)
