Code B3031 2014 Chevrolet Silverado Description

When learning a coded key, the Body Control Module (BCM) is placed in learn mode. Diagnostic Trouble Code (DTC) B3031 will be set automatically as an indicator that the system is in learning mode and not as a fault indicator. On some model-year vehicles, the instructions for adding keys includes the direction to always use two learned keys. This DTC will be set if that direction is not followed. If only one learned key is available, then Replacing Keys must be performed. Once the coded key is learned, learn mode will be exited and the DTC cleared. If the BCM does not exit learn mode, DTC B3031 will remain current and indicate a fault. The instrument cluster security indicator will illuminate, and the driver information center will display a message.
