Diagnostic Fault Information



Circuit/System Description



The cruise control switch is an input to the body control module (BCM). The BCM monitors the cruise control on/off, set/coast, 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 specific voltage signal on the cruise control switch signal circuit when a switch is applied. The BCM sends a serial data



message to the engine control module (ECM) indicating the status of the cruise control switches.



Conditions for Running the DTC
