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.
