Keyless/Power Door Locks/Security System Description

Security Alarm System

The security alarm system arms automatically after the doors, hood, and trunk lid are closed and locked. For the system to arm, the ignition switch must be in the LOCK (0), with the key removed from the ignition switch, and the MICU must receive inputs that the doors, hood, and trunk lid 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, or by grabbing the outer door handle with the keyless access remote in range.

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 10-12 V, including the key cylinder switches. The security indicator in the gauge control module begins to flash immediately after the doors, hood, and trunk lid are closed and locked, and shortly 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, or there is a short in to ground in its circuit (0 V), 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 vehicle, or something bumping into the vehicle could cause the alarm to sound.

NOTE: There is no glass breakage or motion detection 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 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 trunk lid is forced open
- A door is unlocked without using the built-in key or the remote
- The hood is opened
- The audio unit is disconnected
- The remote panic is operated

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 by pressing any button on the remote.

NOTE: The security system can be customized to suit client needs using the multi-information display (MID). 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 remote is pressed and held for about 2 seconds, the alarm sounds and the exterior 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 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. Remotes 1 and 2 (Identified on the back of each remote) are linked to the DPMS, keyless access control unit, the climate control settings, the custom memory settings (in the MID), and the illumination settings. Depending on which remote 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 10 mph.
- AUTO DOOR UNLOCK: Door unlocking can be turned off, or turned on when shifting to Park or turning the ignition switch OFF.
- WHENEVER UNLOCKING: Door unlocking can be set to unlock all doors or only the driver's door on the first push.
- KEYLESS DOOR LOCK ACKNOWLEDGMENT: The beep and the front parking 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 in five steps (MIN/LOW/MID/HIGH/MAX).
- INTERIOR LIGHT DIMMING TIMER: 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 remotes 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 remote blinks twice when linked, and once when unlinked.

The keyless entry system allows you to lock and unlock the vehicle with the remote. 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 once, only the driver's door unlocks, if keyless memory setting "WHENEVER UNLOCKING" 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 "WHENEVER UNLOCKING" is set to All Doors. The doors do not lock with the remote if a door is not fully closed, or if the remote's built-in key is in the ignition switch.

If the UNLOCK button is pressed, released, then pressed and held, the power 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 in the "DOOR" position, the individual map lights come on when the UNLOCK button is pressed. If a door is not opened, the lights go off in about 30, 60, or 90 seconds (depending on the keyless memory setting "SECURITY RELOCK TIMER"), and the doors relock. If the doors are locked with the remote within 30 seconds, the lights go off immediately.

Power Door Lock System

The power door lock system locks and unlocks all four doors with the driver's or passenger's master door lock switch. The doors can be locked and unlocked using the remote's built-in key in the driver's door key cylinder switch. If the key is turned counterclockwise, all the doors lock. If the key is turned clockwise once, the driver's door unlocks, and when the key is released, then turned again, the other doors unlock.

The doors can also be locked by pushing down on the lock knob on the driver's door. Pulling up on the lock knob only unlocks the driver's door. The lock knobs on the other doors only lock and unlock that door.

If the remote's built-in key is in the ignition, and a door is open, the doors will not lock using the master door lock switches and the driver's MPCS will automatically unlock the doors if you push down on the driver's door lock knob.
