Keyless/Power Door Locks/Security System

System Description

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 system 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 acknowledgement 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 any time by unlocking the driver's door with the key or by pressing any button on the remote transmitter.

Panic Mode
The panic mode sounds the alarm in order to attract attention. When the PANIC button on the remote transmitter 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 transmitter or by turning the ignition switch ON (II). The panic mode will not function if the ignition switch is ON (II).

Power Door Lock System
The power door lock system locks and unlocks all four doors with the driver's master door lock switch and the passenger's door lock switch. The doors and the tailgate (without power) can be locked and unlocked using the key in the driver's door key cylinder switch. If the key is turned counterclockwise, all the doors and tailgate 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 and tailgate unlock.

The doors and tailgate 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 key is in the ignition switch, and a door is open, the doors will not lock using the master door lock switch.

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 keyless receiver unit built into the power window master switch. The keyless entry system allows you to lock and unlock the vehicle with the remote 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). For Touring model, the remote transmitters 1 and 2 (Identified on the back of the remote) are linked to the DPMS, and the custom memory settings (in the MID). Depending on which remote transmitter unlocks the vehicle, these settings are chosen. The remote transmitter can also be unlinked to cancel this feature.

Some functions of the security, keyless entry and power door locks can be customized using the MID keyless memory setting (Touring model only). 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.
- ONE TOUCH UNLOCK (Touring model): Door unlocking can be set to unlock all doors or only the driver's door with one touch of the button.
- KEYLESS DOOR LOCK ACKNOWLEDGEMENT: The beep, the parking lights and taillights can be turned on or off when pressing the LOCK button a second time on the remote transmitter.
- SECURITY RELOCK TIMER: Select the time (30, 60, or 90 sec.) that the doors relock if you unlock the doors with the remote transmitter, 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 and closing the driver's door.
- 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.
- FRONT WIPERS OPERATION: Select the windshield intermittent wiper dwell time control to manually adjustment type or automatic type link with the vehicle speed.
- COMPASS CALIBRATION: Calibrate the compass area zone.
- MEMORY SEAT LINK: The remote transmitters can recall the memorized driving position by pressing the LOCK and UNLOCK buttons at the same time for about 1 second.

When you press the UNLOCK button the first time, only the driver's door unlocks. The other doors unlock when you press the UNLOCK button a second time. All the doors unlock when you press the UNLOCK button first time if you press the LOCK button and the PASSENGER SIDE SLIDING DOOR button at same time for about 1 second, the LED in the remote transmitter will blink twice. To cancel this feature, press the LOCK button and the PASSENGER SIDE SLIDING DOOR button at the same time, the LED will blink once.

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

For EX, EX-L, and Touring models:
If the UNLOCK button is pressed, released, then pressed and held, the windows begin to open. The windows stop if the button is released. See power windows for more information and troubleshooting.

For Touring model:
When the interior lights switch is in the middle (door) position, 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 15, 30, or 60 seconds (depending on
the keyless memory setting "INTERIOR LIGHT DIMMING TIMER"), and the doors will relock. If the doors are locked with the remote transmitter within 30 seconds, the light will go off immediately.

If the doors are unlocked using the remote transmitter, and no doors are open, the multiplex integrated control system will relock the doors in about 30 seconds.

For EX, EX-L, and Touring models, the security system will rearm itself.
