Circuit/System Description

When learning a coded key, the BCM will remain in programming mode. DTC B3031 is activated automatically as an indication that the system is in programming mode and does not indicate a fault. Once the coded key is learned, learn mode will be exited and the DTC cleared. If the BCM does not exit learn mode, B3031 will remain current and indicate a fault. The instrument cluster security indicator will turn ON and the driver information center will display a message.
