Code B3794:08 2014 Chevrolet Silverado 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 Diagnostic Trouble Code (DTC) will be set when the BCM detects an invalid voltage signal on the cruise control switch signal circuit for 1 second.
