Security System

How the Circuit Works
Instead of a single control unit, the security system uses a door multiplex control unit, driver's multiplex control unit, and passenger's multiplex control unit to receive inputs from the door switches and other components.

The security system is activated automatically 15 seconds after the hood, trunk, and all the doors have been closed and locked. The security indicator on the driver's door panel will flash after the system is activated.

If any of the following conditions occur, the horns will sound and the headlights, side marker lights, parking lights, and taillights will flash for about two minutes unless the system is disarmed by unlocking either front door with the key.
- Any door is opened forcibly.
- Trunk lid is opened without the key.
- Hood is opened.
- Engine starter circuit and battery circuit are bypassed by breaking the ignition switch.
- Hood/trunk lid opener is operated.
- Panic button on the transmitter is pushed.
