Security Alarm System
22-114Keyless/Power Door Locks/Security System
System Description
The security alarm system is armed automatically after the doors, hood, and trunk are closed and locked. For the
system to arm, the ignition switch must be to LOCK (0), the key must be removed from the ignition switch, and the
MICU must receive signals that the doors, hood, and trunk 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 i
nputs that are grounded, and have 0 V, are the driver’s door lock knob
switch (LOCK position), and the audio unit or navigation unit (if equipped). 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 (speedo) begins to flash immediately after the vehicle is completely closed and locked, and 15 seconds later,
the security system arms. If the security indicator does not flash, the system is not arming. 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.
If one of the switches is misadjusted or shorted internally, or there is a short in the circuit, the security system will not
arm. As long as the control unit continues to receive a ground signal (0 V), 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. 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 to 10 to 12 V. The system sounds the alarm when any of these
occur:
 A door or the trunk is forced open.
 A door is unlocked without using the 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 horn sounds and the exterior 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.

NOTE: If both of the front and console accessory power
sockets do not work, check the No. 35 (7.5 A) fuse in the
under-dash fuse/relay box. 1. Remove the center panel.  With audio:– ’06-08 models (see page 23-80)
– ’09 model (see page 23-256)
 With navigation: – ’06-08 models (see page 23-155)
– ’09 model (see page 23-355)
2. Disconnect the 2P connector (A) from the front accessory power socket (B).
3. Inspect the connector terminals to be sure they are all making good contact.
 If the terminals are bent, loose, or corroded, repair them as necessary and recheck the system.
 IftheterminalslookOK,gotostep4.
4. Turn the ignition switch to ACC (I).
5. Measure the voltage between front accessory power socket 2P connector terminal No. 1 and body
ground. There should be battery voltage.
 If there is battery voltage, go to step 6.
 If there is no voltage, check for: – Blown No. 29 (15 A) fuse in the under-dash fuse/relay box.
– Faulty front accessory power socket relay.
– Poor ground (G 503).
– Anopeninthewire. 6. Check for continuity between front accessory
power socket 2P connector terminal No. 2 and body
ground. There should be continuity.
 If there is continuity, replace the power socket; go to step 7.
 If there is no continuity, check for: – Poor ground (G 502).
– Anopeninthewire.
7. Remove the socket (A).
8. Remove the housing (A) from the panel.
9. Install the front accessory power socket in the reverse order of removal.

23-6 Audio System
System Description
The audio unit acts as the processor for all audio functions. Select audio functions from the audio unit, the audio
remote (on the steering wheel), or by using the navigation voice control system. The audio display provides the
current audio status. For vehicles with navigation, additional audio information is available by touching the audio
button on the navigation audio screen (See the owner’s manual and the navigation system manual for more details.).
The XM receiver passes its signal to the audio unit. In addition, it communicates with the audio unit via the GA-Net bus.
Any open connections in the GA-Net bus circuit causes audio and navigation functions to appear inoperative.
For vehicles with navigation, pressing the open/close switch on the navigation display panel allows access to the CD
slot and PC card.
A security signal is daisy-chained between the audio and vehicle components for integration into the vehicle’s security
system.
Some audio systems are equipped with speed-sensitive volume compensation (SVC). The navigation or audio unit
receives the vehicle speed pulse (VSP) from the ECM/PCM. The system processes the speed input and increases the
navigation or audio system volume level as the vehicle speed increases to compensate for the various interior noises
that occur at higher speeds. When the vehicle slows down, the volume returns to its normal level. The SVC has four
settings: SVC OFF, LOW, MID and HIGH that can be adjusted using the navigation or audio unit. The SVC comes from
the factory with the MID setting as the default.
To change the audio unit SVC setting, press the tune folder sound knob repeatedly until the SVC is displayed, rotate
the knob to adjust the SVC to the desired setting (SVC OFF, LOW, MID, or HIGH).
To change the navigation unit SVC setting, press the AUDIO button, and then select the SOUND icon on the navigation
display. Press the navigation display to select the desired setting (OFF, LOW, MID, HI).
The navigation system allows voice control for the audio, XM, PC card, and CD player. The GA-Net (audio unit)
communicates the voice control commands. When using the navigation TALK/BACK button, the audio is muted on all
speakers and you hear navigation sound on the front channels. When using the navigation or route guidance (RG), the
front speakers provides the navigation sound and the rear speakers continue to play. For more information, see the
navigation section. The outline of the interruption function is shown in this table.
