Keyless/Power Door Locks/Security System Description

Security Alarm System

The security alarm system is integrated with the multiplex integrated control system. For the system to arm, the ignition switch must be in the LOCK (0) position, 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 armed or disarmed at any time by locking or unlocking the driver's door with the key or pressing the LOCK/UNLOCK button on the transmitter. The alarm can also be armed by locking (with the lock knob) then closing the driver's door.

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 5.0 V in sleep mode or 12 V in awake mode, including the key cylinder switches. The security indicator in the gauge control module begins to flash immediately after the doors, tailgate, and hood are closed and locked, and then, after 20 seconds, the flashing intervals of the security indicator change to indicate that the alarm is fully armed. If the security indicator does not flash, the system is not arming. If the LOCK button is pressed a second time within 5 seconds (Keyless LOCK acknowledgement is turned ON) and the vehicle is completely closed and locked, the keyless buzzer sounds, and the parking lights and the side marker lights flash one time to confirm the security alarm system is armed.

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 5-12 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 5-12 V, 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 tailgate is forced open
- A door is unlocked without using the key or the transmitter
- The hood is opened
- The audio unit (or navigation unit, rear controller and screen) is disconnected
- The transmitter panic is operated
- The ignition switch is turned ON (II)

When the system sounds the alarm, the horns sound, and the parking lights and the side marker 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 transmitter.

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 about 2 seconds, the horns sound, and the parking lights and the side marker lights flash for about 20 seconds.

The panic mode can be cancelled at anytime by pressing any button on the remote or by turning the ignition switch 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. Transmitters 1 and 2 (Identified on the back of each transmitter) are linked to the DPMS, the climate control settings, the custom memory settings (in the MID), the audio, the navigation and the illumination settings. Depending on which transmitter unlocks the vehicle, these settings are chosen.

Some functions of the security, keyless entry, and power door locks can be customized using the MID keyless memory setting. They include:

- AUTO DOOR LOCK: Door locking can be turned off, or turned on when shifting from Park or at a speed above 15 mph.
- AUTO DOOR UNLOCK: Door unlocking can be turned off, or turned on when shifting to Park or turning the ignition switch to LOCK (0).
- KEY AND REMOTE UNLOCK MODE: Door unlocking can be set to unlock all doors or only the driver's door on the first push.
- KEYLESS DOOR LOCK ACKNOWLEDGMENT: The keyless buzzer, the parking lights and the side marker lights can be turned on or off when pressing the LOCK/UNLOCK button on the remote.
- SECURITY RELOCK TIMER: Select the time (30, 60, or 90 sec.) that the doors relock if you unlock the doors with the remote, but do not open any of them.
- HEADLIGHT AUTO OFF TIMER: Select time (0, 15, 30, or 60 sec.) to turn the headlights off after removing the key from the ignition opening, then closing the driver's door.
- AUTO LIGHT SENSITIVITY: Automatic lighting sensor sensitivity can be adjusted five steps (MIN/LOW/MID/HIGH/MAX).
- INTERIOR LIGHT DIMMING TIME: Select the dimming time (15, 30, or 60 sec.) of the interior lights after closing the door with the key removed from the ignition.

The transmitters can be linked and unlinked to the keyless memory settings by pressing the LOCK and UNLOCK buttons at the same time for about 1 second. The LED on the transmitter blinks twice when unlinked, and once when linked.

The keyless entry system allows you to lock and unlock the vehicle with the transmitter. When you press the LOCK button, all the doors lock (unless any one of the doors is not fully closed or the key is in the ignition switch).

When you press the UNLOCK button the first time, only the driver's door unlocks, if keyless memory setting "KEY AND REMOTE UNLOCK MODE" is set to Driver's Door. The other doors unlock when you press the UNLOCK button a second time. All the doors unlock when you press the UNLOCK button the first time if keyless memory setting "KEY AND REMOTE UNLOCK MODE" is set to All Doors.

NOTE: The doors will not lock with the transmitter if a door is not fully closed, or if the ignition key is in the ignition switch.

If the UNLOCK button is pressed, released, then pressed and held, the windows and the moonroof begin to open. The windows and the moonroof stop if the button is released. The windows and moonroof cannot be closed with the remote. See power windows for more information and troubleshooting.

When the interior lights switch is set to the "DOOR" mode, the individual map lights will come on when the UNLOCK button is pressed. If a door is not opened, the lights will go off in about 30, 60, or 90 seconds (depending on the keyless memory setting "SECURITY RELOCK TIMER"), and the doors will relock. If the doors are locked with the transmitter within 30 seconds, the lights will go off immediately.
