Security Alarm System

The security alarm system is integrated with the multiplex integrated control system, and arms automatically after the doors, hood, and tailgate 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, and tailgate 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 (a door must be opened to completely disarm the alarm).

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 about 0.8 V in sleep mode and 5 V or more in awake mode, including the key cylinder switches. With the doors, tailgate, and hood closed and locked, the multiplex integrated control system sends a signal to the gauge control module to flash the security indicator. The security indicator will begin to flash at a long ON long OFF rate, signaling that the multiplex integrated control system has verified the inputs are correct. About 15 seconds after the security indicator begins to flash, the security system will arm and the security indicator will flash at a short ON short OFF rate. If the security indicator does not flash, the system is not armed.

If the doors and tailgate are locked using the remote transmitter, and the inputs are correct, the multiplex integrated control system will flash the parking lights and taillights, and the security indicator will begin to flash. If the parking lights and taillights do not flash, the system is not armed.

If the remote transmitter lock button is pressed a second time within 5 seconds of the first, and the Keyless lock acknowledgment is activated. The multiplex integrated control system will sound the horn one time and flash the parking lights and taillights to confirm the security system is armed. The multiplex integrated control system will sound the alarm when any of the following occur while the security system is set.

• A door or the tailgate 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 RES DVD player or rear display is disconnected (with RES)
• The navigation unit is disconnected (with navigation)
• The ignition switch is turned ON (II)

There is no glass breakage sensor or motion detector sensor.

A switch that is misadjusted or a poor connection can cause the alarm to sound for no apparent reason. In this case, a significant change in temperature, inside or outside the vehicle, the vibration from a passing vehicle, or something bumping into the vehicle may cause the loose connection or misadjusted switch to shift slightly and the alarm will sound.

If the multiplex integrated control system detects a drop in voltage on the switches (0 V) or voltage, on the driver's door lock switch (lock wire) or the audio unit security circuit, the horn will sound and the headlights and taillights will flash for about 2 minutes. The alarm can be stopped at anytime by unlocking the driver's door with the key or by pressing any button on the remote transmitter.
