DTC P0567



- Cruise Control Resume Switch Circuit



DTC P0568



- Cruise Control Set Switch Circuit



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



* The cruise switch is ON.



* The ignition is ON.



Conditions for Setting the DTC



* The BCM detects an invalid voltage signal on the cruise control switch signal circuit for greater than 2 seconds and sends a serial data



message to the ECM. The ECM sets these DTCs when the message is received.



* The ECM runs this diagnostic every 0.05 second.



Actions Taken When the DTC Sets



DTCs P0564, P0567, or P0568 are type C DTCs.



Conditions for Clearing the DTC



DTCs P0564, P0567, or P0568 are type C DTCs.
