Circuit/System Description

The cruise control switch is an input to the body control module (BCM). The BCM monitors the cruise control switch signal circuit in order to detect when the driver has requested to perform a cruise control function. The BCM detects a specific voltage signal on the cruise control switch signal circuit when a switch is applied. The BCM sends a GMLAN serial data message to the engine control module (ECM) indicating the status of the cruise control switch.
