Lock/Unlock with Key Cylinder
WARNING: This page is about a different car, the 2010 Suzuki Kizashi. However, it is still accessible from the selected car via links, so may be relevant.
When the lock or unlock signal from key cylinder switch is inputted into keyless start control module by key cylinder operation, keyless start control module outputs door lock/unlock request signal (depending on the door lock switch state) to BCM through CAN communication. When BCM receives signal, it activates each door lock actuator.
