Vehicle Security System Alarm Operation

The vehicle security system is triggered by

• opening a door
• opening the trunk
• unlocking door or trunk without using the key, keyfob or Intelligent Key.

The vehicle security system will be triggered once the system is in armed phase,

• when BCM receives a ground signal at terminals 12, 13, 47, 48 (front or rear door switch), or terminal 42 (trunk switch).

When the vehicle security system is triggered, ground is supplied intermittently

• from IPDM E/R terminal 13
• to horn relay terminal 1.

The headlamps flash and the horn sounds intermittently.

The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
