Code B3106 2016 GMC Sierra Description

The Body Control Module (BCM) communicates with the Remote Control Door Lock Receiver (RCDLR) through the keyless entry serial data circuits. When any button on the keyless entry transmitter is pressed, the transmitter sends a signal to the RCDLR. The RCDLR sends a function request to the body control module, depending on which button is pressed on the transmitter. The BCM receives the message and performs the appropriate function. The Diagnostic Trouble Code (DTC) will be set when the transmitter that is sending a signal to the RCDLR is different from those transmitters stored in the BCM.
