How come it beeps on the 2nd press of the remote and not the 1st? Is it a like a two stage lock where the first locks one door and then the rest? I know there's settings in the computer but nothing for the alarm

Thanks

 

Security Alarm System

The security alarm system is integrated with the multiplex integrated control system, and arms automatically after the doors, hood, and trunk are closed and locked. For the system to arm, the ignition switch must be off, the key must be removed, and the MICU must receive signals that the doors, hood, trunk are closed and locked. The alarm can be disarmed at any time by unlocking the driver's door with the key or pressing the UNLOCK button on the remote transmitter.

When everything is closed and locked, the only inputs that are grounded, and have 0 V, are the driver's door lock knob switch (LOCK position), and the audio unit. In other words, all of the other switches are open, and have 0.8 V- 5 V, including the key cylinder switches. The security indicator at the driver's door begins to flash immediately after the doors, trunk, and hood are closed and locked, and shorty later, the security system arms and the security indicator flashes on for a shorter amount of time than before. If the security indicator does not flash, the system is not arming. If the vehicle is completely closed and locked, a beep sounds and parking lights flash to confirm the security alarm system is armed if the LOCK button is pressed a second time within 5 seconds, and the keyless lock acknowledgment is turned on.

If one of the switches is misadjusted or shorted internally (0 V), or there is a short in the circuit (0 V), the security system will not arm. A switch that is slightly misadjusted can cause the alarm to sound for no apparent reason. In this case, a significant change in outside air temperature, the vibration of a passing vehicle, or something bumping into the vehicle could cause the alarm to sound. There is no glass breakage or motion detector feature.

If anything is opened or improperly unlocked after the system is armed, the control unit receives a ground signal from that switch, the 0.8 V-5.0 V reference drops to 0 V, and the system sounds the alarm. If the audio unit is disconnected, the input loses its ground, and the input voltage goes to 5.0 V or more, and the system sounds the alarm.

The system sounds the alarm when any of following occur while the security system is armed:

• A door or the trunk is forced open
  
• A door is unlocked without using the key or the remote transmitter
  
• The hood is opened
  
• The audio unit is disconnected
  
• The remote panic is operated
  
• The ignition switch is turned ON (II)
  

When the system sounds the alarm, the horns sound and the exterior lights flash for 2 minutes. The alarm can be stopped at any time by unlocking the driver's door with the key or by pressing any button on the remote transmitter.
