Circuit/System Description

WARNING: This page is about a different car, the 2011 Chevrolet Volt. However, it is still accessible from the selected car via links, so may be relevant.

The cruise control switch is an input to the body control module (BCM). The BCM monitors the cruise control on/off, set/coast, the resume/accelerate and cancel switches via 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 predetermined voltage signal when a cruise control function switch is applied, with each switch having a different voltage value.
