Code P0568 2017 GMC Sierra 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 Engine Control Module (ECM) receives the requested cruise control switch function from the BCM via a serial data message. The BCM monitors the cruise control switch. The BCM sets the OBDII code when the cruise control switch is not to factory specifications. 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 the Diagnostic Trouble Code (DTC) when the message is received.
