Keyless/Power Door Locks/Security System Description

Security Alarm System

The security alarm system automatically arms after the doors, hood, and tailgate are closed and locked. For the system to arm, the ignition switch must be in the LOCK (0) position, the key must be removed from the ignition switch, and the MICU must receive inputs 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 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) input, and the audio unit or navigation unit (if equipped) security input. In other words, all of the other switches are open, and have about 10 to 12 V, including the key cylinder switches. The security indicator in the gauge control module begins to flash immediately after the vehicle is completely closed and locked, and 15 seconds later, the security system arms (blink rate changes from slow to fast). If the security indicator does not flash, the system is not arming. Horns sound, and the parking lights, the side marker lights, the taillights, and the license plate lights flash to confirm the security system is armed if the LOCK button is pressed a second time within 5 seconds.

If one of the switches is misadjusted or shorted internally, or there is a short to ground in its circuit, the security system will not arm. As long as the control unit continues to receive a ground input (0 V) except for the driver's door lock/unlock knob switch input, it senses that the vehicle is not closed and locked, and the 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 truck, or someone bumping into the vehicle could cause the alarm to sound.

NOTE: 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, and the 10 to 12 V reference drops to 0 V. If the audio unit or navigation unit (if equipped) is disconnected, the input loses its ground, and the input voltage goes from 0 V to 10 to 12 V. The system sounds the alarm when any of these occur:

- A door or the tailgate is forced open.
- A door is unlocked without using the built-in key or the transmitter.
- The hood is opened.
- The audio unit or navigation unit (if equipped) is disconnected.
- The transmitter PANIC button is pressed.

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 or by pressing any button on the transmitter.

NOTE: The security system can be customized in the multi-information display (MID) to suit the client needs. For more information about keyless/security system options, refer to the Owner's Manual.

Panic Mode

The panic mode sounds the alarm in order to attract attention. When the PANIC button on the transmitter is pressed and held for 2 seconds, the horns sound and the exterior lights flash for about 20 seconds.

The panic mode can be canceled at anytime by pressing any button on the transmitter or by turning the ignition switch to ON (II). The panic mode will not function if the ignition switch is in ON (II).

Keyless Entry System

The keyless entry system is integrated with the multiplex integrated control system. The multiplex integrated control unit (MICU) receives LOCK, UNLOCK and PANIC signals from the immobilizer-keyless control unit (keyless receiver).

The keyless entry system allows you to lock and unlock the vehicle with the transmitter. When you press the LOCK button, all doors lock. When you press the UNLOCK button once, only the driver's door unlocks. The other doors will unlock when you press the button a second time (Depending on the settings in the MID, all the doors may unlock when you press the button the first time). The doors will not lock with the transmitter if a door is not fully closed, or if the key is in the ignition switch.

When the switch for the interior light and the ceiling light is in the center (DOOR) position, it comes on when the UNLOCK button is pressed. If a door is not opened, the light goes off in about 15 to 60 seconds, (depending on the customized selections), and the door relock in about 30 to 90 seconds (depending on the customized selections). If the doors are not locked with the remote, the light goes off immediately.

NOTE: The keyless system can be customized in the multi-information display (MID) to suit the client's needs. For more information about keyless/security system options, refer to the Owner's Manual.
