Tech

nical description of alarm function:

SK BCM is designed to indicate intrusion into the vehicle by unauthorized door open. SK BCM

ceives CAN Signal of any door open including engine hood and trunk, and then SK BCM send CAN

signal to SJB (Smart Junction Box) so that SJB can drive Alarm device such as horn and visible

Lamp for 27s.

When alarm state is set by Foldingkey, SK BCM check all door lock status by CAN signal.

And then SK BCM enters alarm system mode and drives Security Indicator which shows

alarm setting status to the operator. SK BCM provides an alarm setting locking function to

prevent inadvertent setting of the alarm when KEY is inserted in the Key Hole.
