Normal Operation
Smart lock unlocks the driver door if the key is in the ignition and the driver door is open when the vehicle is locked with the interior door lock control switch remote keyless entry (RKE) keypad, or RKE transmitter. The smart locking feature requests that driver door be unlocked 1 second after these conditions arise. The smart lock feature unlocks the driver door only if the keycode programming and transmitter identification code (TIC) programming modes are not active.

Possible Causes
- circuit 57 (BK) open
- circuit 344 (BK/YE) ope
- driver door ajar switch
- universal asynchronous receiver-transmitter (UART)-based protocol (UBP) communications network
- vehicle security module
