Content Theft Deterrent (CTD) Description and Operation
The CTD system (when armed) is designed to deter vehicle content theft by pulsing the horns and exterior lamps for approximately 2 minutes when an unauthorized vehicle entry is detected. However, the CTD system does not affect engine starting.
An unauthorized entry can be any of the following with the CTD system armed:
• Forced entry into the passenger compartment.
• When any door is opened without being unlocked by using the key to unlock either of the front doors or the UNLOCK command from a Keyless Entry Transmitter.
• Forced entry into the rear compartment.
The components of the system are:
• Keyless Entry Module (Remote Control Door Lock Receiver)
• Door Ajar Switches
• Body Control Module
• Front Door Lock Cylinder Switches
• Power Door Lock Switches

The CTD system is an internal function of the Body Control Module (BCM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the BCM detects an unauthorized entry, it activates the horns and exterior lamps. The BCM has five basic modes (disarmed, standby, delayed, armed, and alarm) for operating the CTD system. The different modes are described below.
The BCM has the CTD system in a disarmed mode until the following conditions are detected:
• Ignition key turned to the OFF position.
• Any door open.
• Doors locked by either the power door lock switch or the LOCK button on the transmitter.
The BCM enters the standby mode when the above conditions are detected. In standby mode, the BCM commands the SECURITY indicator to flash. If all the doors are closed and the LOCK button on the transmitter is used, the BCM enters the delayed mode.
When the last door is closed, the BCM enters the delayed mode for 30 seconds. In delayed mode the BCM commands the SECURITY indicator to illuminate ON steady.
After 30 seconds, the BCM enters the armed mode. Any forced entry activates the alarm mode.
When the BCM detects a forced entry, the BCM enters the alarm mode. The BCM activates the horns and exterior lamps for 2minutes. This is followed by a three minute time-out with the horn no longer active. If no new intrusions are detected after the time-out, the horn is not active.The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode .
There are no fuse's for the alarm , there are main power feeds to the BCM .

Who replaced the headlamp bulb ? Take it back . Everything your having problems with are all controlled by the BCM - body control module . May have crossed wire's ,shorted etc....
This vehicles BCM functions as the Power Mode Master (PMM). Refer to Power Mode Description and Operation for a complete description of the power mode functions.

As far as the sliding doors , pull the fuse's

double posted. wow.
when it beeped, did you look in the display (RPM)
it tells you why?? the VFD or EVIC tells you why.? (rpm dial)
do you park with the alarm on , on the street or a garage?????
if in a garage park and turn alarm off. it does turn off the alarm.
did you bump the panic button?
eg its under your pillow?? LOL or the cat chewed it?
read your other post, it's got lots of answer there.
to find cause.
if the horns stays off, if alarm is off then its not the horn button.

as many will say. there are 4 things that run the horn.
button horn
alarm
door locks.
panic.(part of alarm but not totally)
on my car, i have most themn turned off, like the lamp flashings.
and the horn chirp is off on all my cars, all i get is the door lock click sounds, nice (neighbor friendly)
so turn all all that and see if the horn still fails.

that panic button can fail,
if mind did id pull the fob battery and then use FOB 2.
to see of the FOB fails.

your other post said driving
this one says, parked. 3am clue.

I think you have a BCM - body control module problem ! The BCM controls the automatic door locks .
Automatic Door Lock Operation
This BCM controlled feature can be personalized to driver preference. Refer to Power Door Systems Connector End Views Personalization Description and Operation in Personalization.
The BCM will automatically lock the vehicle doors if the following conditions exist:
?€¢
All vehicles doors are closed.

?€¢
The ignition is in the ON position.

?€¢
The vehicle is shifted out of PARK.

The BCM will then unlock the doors when the ignition is placed in the OFF position. Do the exterior lights flash as well as the horn sounding ?
Body Control Module (BCM)
The
Content Theft Deterrent
system is an internal function of the Body Control Module (BCM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the BCM detects an unauthorized entry, it activates the horns and exterior lamps.
When the BCM detects an unauthorized entry, the BCM enters the alarm mode. The BCM activates the horns and exterior lamps for 2 minutes. This is followed by a 3 minute time-out with the horn no longer active. If no new intrusions are detected after the time-out, the horn is not active. The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode.

Sounds like you have a problem with the BCM. Almost all manufacturers put all controls now through the BCM, its a really convenient way to get a lot of cash out of you, since any single item in the BCM that goes require the entire BCM to be replaced.

The 2005 Dodge Caravans have software problem in the BCM that causes the power locks to quit working. The only fix is to bring the van to a dealer for a software flash update.Read more: http://wiki.answers.com/Q/Where_is_the_fuse_located_for_power_door_locks_on_a_2005_Dodge_Grand_Caravan #ixzz271oz6ROB


disconnect the battery cable and pull the BCM fuse and do system reset and the door locks may work fine again.



also ro try to get the power door locks working. pull and reinstall (but not replace) all fuses and fuse blocks (but not the relays). The locks may start working after that.

disconnecting and reconnecting the lamp and horn relays may fix same issue with the locks.
Several people suggested resetting the fuses under the hood, and it worked. Others tried unplugging and plugging back in the battery and that also worked for them.

CODE ALARM SYSTEM

Used on:
Impreza 1996-2001
Legacy 1995-1999
Forester 1998-2000

Battery GP-23A

Lock: Left button will lock all doors. Double chirp indicates locked.
Unlock: Right button will unlock driver's door only. Hold unlock button app 6 seconds, it will unlock all doors including rear gate. Single chirp indicated unlock.
If the car chirps or lights flash 4x the alarm was triggered.
Panic. Press both buttons to activate emergency honk and flashing lights.
Valet mode: With optional alarm onlyPress the red alarm button on the left of the steering wheel. The light will quickly double flash. To re-set back to normal mode, press the red alarm light button again

Battery failed and lights flashing?
Parking lights will flash when the vehicle's battery is disconnected and reconnected.
To stop lights from flashing, either:
Press remote transmitter "UNLOCK" button once OR turn the ignition switch to the "ON" position and press programming button for one second (see below).
The vehicle interior (courtesy) light and door open warning light (DOOR AJAR indicator) will then illuminate for 60 seconds when the ignition is turned off, or until the doors are locked with the remote transmitter. Yes, the dashboard instrument panel lights will flash when the parking lights flash.

Programming or Overriding the Alarm when you have lost the remote
Open driver's door.
Turn ignition key to 'On'
Press and *hold programming button* in (see diagram, button under dashboard)
After 15 seconds the the door locks will cycle 3 times. Do not release Programming button.
Press lock (left) button the remotes to be programmed. The door locks will cycle one time. Exit programming mode by releasing Programming button under dashboard and turning key to off.

Code Alarm Programming Button is under dashboard on the kick panel by the driver's left knee, left of the steering column. If you can't find it, it might still be tucked up in the wiring harness higher up in that same general area. The botton is recessed in a plastic ring (see diagram).
This button must be pressed while programming remotes or if the battery was disconnected and the lights are flashing.

This is probably caused by:

a loose door switch, or

a loose connection to a door switch, or

a defective (dirty / corroded) door switch.

There is a false signal being sent that a door is open / ajar.
