How do you turn off an alarm for a 2005 Saturn Ion


Disarming an Armed System/Silencing an Alarm
If system arming has been requested by the keyless entry transmitter, it must be disarmed.
Important: Using the power door unlock switch or manually unlocking the doors does not disable the CTD armed mode. Also, disconnecting the battery or pulling fuses does not disable the armed mode, since the BCM stores the CTD mode status in memory.
?€¢
To disarm the CTD system in arm pending mode, SECURITY indicator flashing and doors open, perform 1 of the following:


-
Press the UNLOCK button on the keyless entry transmitter.


-
Insert a valid key into the ignition and start the vehicle.


?€¢
To disarm the CTD system in the armed mode:


-
Press the UNLOCK button on the keyless entry transmitter.


-
Insert a valid key into the ignition and start the vehicle.


?€¢
To disarm the CTD system when activated, alarming mode.

Where is the alarm system on 2005 lincoln ls?


Anti-Theft - Perimeter The anti-theft perimeter protection feature is controlled by the front electronic module (FEM), the rear electronic module (REM), and the driver door module (DDM). The alarm can be armed using:
  • the LOCK button in the remote keyless entry (RKE) transmitter to the DDM, which sends a message through the standard corporate protocol (SCP) communications network to the FEM.
  • the driver or passenger door lock switch if the corresponding door is open when LOCK is actuated.
  • the key in the driver door lock cylinder.
  • the RKE keypad by pressing 7/8 and 9/0 simultaneously.
The FEM and REM then monitor all features, which activate the alarm in the event of an unauthorized entry.
The luggage compartment lid lock cylinder does not disarm the vehicle's perimeter alarm. The luggage compartment alarm can be temporarily inhibited through the luggage compartment lid disarm switch, located in the luggage compartment lock cylinder or by opening the lugguage compartment with the RKE transmitter or the RKE keypad. Once the luggage compartment lid closes, the perimeter alarm system immediately starts monitoring the luggage compartment. The perimeter alarm can only be disarmed:
  • by unlocking the vehicle using the RKE transmitter.
  • by unlocking the vehicle using the driver door lock cylinder switch.
  • by cycling to RUN a valid programmed key in the ignition switch.
  • by entering the correct vehicle unlock code on the RKE keypad.
Additionally, an ignition switch tamper circuit and a signal hardwire line from the FEM to the REM are monitored.
If any of the above features receive any activation once the alarm is armed, the alarm activates the visual and audible alerts. ......

Car won't start.Theft light blinks,clicking sound under hood and thumping like horn wants to go off.Seems like it's stuck in anti theft mode


anti theft light should blink every few seconds.

try disconnecting the battery for 15 minutes.

Anti-Theft-Perimeter The perimeter anti-theft system consists of the following components:
  • anti-theft indicator (THEFT)
  • remote anti-theft personality (RAP) module
  • hood switch
  • keyless entry remote transmitter
  • deck lid ajar switch
NOTE: The remote entry features will not function when the ignition switch is in the RUN or ACC position.
Up to four keyless entry remote transmitters (15K601) can be programmed at one time.
The keyless entry remote transmitters :
  • Are programmable.
  • Must be set at the same time.
  • House four buttons.
  • House three buttons (Mexico Anti-Theft System only).
Programming
Refer to Section 501-14B.
Inputs and Outputs
The remote anti-theft personality (RAP) module receives input from the following components for anti-theft operation:
  • Hood switch.
  • Deck lid ajar switch.
  • Keyless entry remote transmitter.
  • Power door lock switches (LH and RH).
  • Door courtesy input.
The RAP module distributes output to the following for the anti-theft system:
  • Power door unlock relay.
  • Power door lock relay.
  • Liftgate unlock relay (Wagon)
  • Park lamps relay.
  • HORN relay.
  • Dome lamp.
  • THEFT indicator.
  • Deck lid release.
Arming
The anti-theft system can be armed if:
  • The ignition switch is in the OFF position.
  • The panic alarm is off.
  • All doors are closed.
NOTE: If a door is open, the anti-theft system is prearmed and waiting for all the doors to be closed. The THEFT indicator will remain illuminated for up to 30 minutes waiting for all the doors to be closed. If a door remains open after 30 minutes, the THEFT indicator will turn off and the system will return to a disarmed state. After all doors are closed and the 30 second prearm (continuous THEFT indicator illumination) is complete, the system is armed.
NOTE: If the theft LED does not flash after 30 seconds, check the LED FLASH PID to see if the feature is enabled.
The anti-theft system will be armed when the lock button on the keyless entry remote transmitter is pressed, all doors are closed and 30 seconds have elapsed.
When the system is armed, the THEFT indicator will flash quickly until the system is triggered or disarmed.
Disarming
NOTE: Using a key in a door lock cylinder to unlock is not a valid method of disarming the anti-theft system.
Untriggered System
NOTE: If the driver arms the system and remains in the vehicle, an untriggered system can be disarmed by turning the ignition switch to the ON position.
An untriggered alarm system can be disarmed by pressing the unlock button on the keyless entry remote transmitter.
Triggered System
NOTE: If the hood or trunk are open when the system is armed, it must be closed and opened again before it can trigger an alarm.
An armed anti-theft system can be triggered by the following conditions:
The deck lid door, liftgate, hood or any door is opened using a key, inside door handle, hood release, etc.
  • The keyless entry remote transmitter can activate a panic alarm which is similar to the anti-theft alarm, but does not cause the THEFT indicator to flash.
A triggered alarm system can be disarmed by:
  • Pressing the unlock or panic button on the keyless entry remote transmitter.
  • Turning the ignition switch to the ON position.
Alarm State When Battery Power Is Cycled
When the RAP module is supplied power the first time at the vehicle assembly plant, the system will be in the disarmed state. The RAP module will remember whether it is armed, disarmed or triggered in its non-volatile memory. When the battery positive cable is removed and then reconnected, the system will return to the state it was in just before the battery was disconnected. If the system is in any prearm state, then the system will return to a disarmed state when the battery is disconnected and then reconnected.

My 2001 tahoe alarm keeps "auto" arming itself after about 30 seconds. How do I stop it from "auto" arming? Its driving me crazy


this alarm works with the remote and the key, if you lock with the key it arms if you lock with remote it arms,when you unlock it it should disarm, if your having a problem with it not working try the pass/side lock with key, that should shut it down but if it keeps rearming without locking doors then it may be aftermarket, also in your manualy it will show you that some factory alarms are also self arming this is programed through the cluster, using the buttons on the dash, you scroll through the options and shut off auto arming, this is done the same way you scroll for mileage or trip time or oil change life. hope this helps.

How do i reset my alarm on a 97 jeep Grand


Here is excerpt from the 1998 Jeep Grand Cherokee Service Manual ... i know you posted under 1997 JGC but this information may be helpful ... by "reset alarm" i believe you meant disarming the alarm?

Arming
Passive arming of the Vehicle Theft Security System (VTSS) occurs when the vehicle is exited with the key removed from the ignition switch, the headlamps are turned off, and the doors are locked using power lock switch. The power lock switch will not function if the key is in the ignition switch or the headlamps are on with the driver’s door open. The VTSS will not arm if either front door or the liftgate are locked using the key in the lock cylinder.
Active arming of the VTSS occurs when the Remote Keyless Entry (RKE) transmitter is used to lock the vehicle, even if the doors and/or the liftgate are open when the RKE transmitter Lock button is depressed. However, the VTSS arming will not be complete until all the doors and the liftgate are closed.
Following successful passive or active VTSS arming, the VTSS set lamp on the top of the instrument panel will flash rapidly for about 15 seconds after the illuminated entry system times out. This indicates that the VTSS arming is in progress. If the light stays on steadily during the arming, it indicates that the hood switch is closed (the hood is open). The VTSS will still arm if the hood is open, but the engine compartment will not be protected. Once the 15 second arming function is complete, the set lamp will flash at a slower rate to indicate that the VTSS is armed. Disarming Passive disarming of the Vehicle Theft Security Sytem (VTSS) occurs when the vehicle is unlocked using the key to unlock either front door or the liftgate. Active disarming of the VTSS occurs when the vehicle is unlocked by depressing the Unlock button of the Remote Keyless Entry (RKE) transmitter. Once the alarm has been activated (horn sounding, exterior lights flashing, and the the engine no-run feature), either disarming method will also deactivate the alarm. Depressing the Panic button on the RKE transmitter will also disarm the VTSS, but the horm will sound and teh exterior lamps will flash for about three minutes as a part of the Panic feature function. ..." And as an additional note, if you have the courtesy interior lights set at 30 seconds like i do, you have to wait until lights go out (with alarm still sounding) before you can disarm the alarm via passive disarm method... what a pain when you don't have the actual RKE handy... Good Luck!

1995 Nissan Maxima alarm system


Hey, I bought my 1995 Nissan Maxima GLE brand new back in July 1994 with factory installed alarm, it just doen't make any sound when you arm or disarm it with remote. The only way you can tell whether it is armed or disarmed is from the lever position of your doors and the blinking red light under the dash. Only the newer versions of Nissan/Infiniti's has the "Audio/Silent" mode button on the remote which allows you to activate/deactivate you car alarm with an audiable sound or no sound at all. No worry, there is nothing wrong with your remote or car alarm.

Replaced the alternator, now anti theft won't disable


The ignition lock anti-theft switch (19A438) detects if the ignition key cylinder is broken or "slam pulled" during a theft. The ignition lock anti-theft switch is always monitored by the remote anti-theft personality (RAP) module. This allows the alarm system to be triggered in the case that the ignition lock anti-theft switch detects tampering of the ignition key cylinder (even in the event that the alarm is not active at the time).
Refer to the Section 501-14B for more details on the keyless entry remote transmitter (15K601).
The door open warning lamp switch (14018) communicates to the RAP module through the generic electronic module (GEM). This input to the RAP will cause the anti-theft alarm to be sounded if the anti-theft alarm was armed.
The door disarm switches are assembled into both LH and RH lock sets. The door disarm switch must be triggered before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.
The RAP module controls the anti-theft system and is the brains of the keyless entry system. The RAP module communicates with the GEM to request that the interior lights be turned ON/OFF with use of the keyless entry remote transmitter, and the GEM communicates to the RAP to inform when the door is opened. Refer to Section 418-00 for inter-module communication.
The RAP module has three wire connectors attached to it:
  • The antenna for the keyless entry remote transmitter.
  • 26 circuit connector (C256).
  • 22 circuit connector (C257).
In addition to the perimeter alarm that uses the door open warning lamp switch, the RAP module also uses the ignition lock anti-theft switch and the autolock/relock feature to prevent theft of the vehicle. For a full description of the autolock/relock system, refer to Section 501-14B .
The THEFT LED is found on the instrument panel between the tachometer scale and the needle pivot point. The LED is illuminated during prearming and flashes when armed or triggered.
Prearming and Arming the System
The system can be armed if:
  • The ignition is OFF.
  • The PANIC alarm is OFF.
  • All doors are closed.
There are two ways to prearm the system:
  • Press the LOCK button on the transmitter.
  • Open a door, press the power door lock button and close the door.
After 30 seconds the system will be armed and the theft indicator in the cluster will flash every two seconds.
Disarming an Untriggered System
An armed system will be disarmed with one of these valid actions:
  1. Pressing the UNLOCK button on the transmitter.
  1. Placing a key in the door and turning to UNLOCK.
  1. Turning the key to RUN or ACC.
The anti-theft alarm can be triggered by the following conditions:
  • The ignition cylinder is damaged with or without the RAP being armed.
  • A door is opened without disarming the armed RAP module.
The remote transmitter can activate a panic alarm which is similar to an anti-theft alarm, but does not deactivate the starter or cause the theft indicator to flash.
Disarming a Triggered System
If the system has been triggered, (the horn honks, the lights flash, and an external starter interrupt relay is engaged), the system can be disarmed by:
  1. Pressing the UNLOCK or PANIC button on the transmitter.
  1. Putting a key in the door and unlocking the door.
  1. Turning the ignition to RUN/ACC (Turning the key to RUN/ACC will not disarm an alarm that has been triggered by the ignition lock anti-theft switch.).

Section 13-11: Anti-Theft System, Active 1998 Windstar Workshop Manual DESCRIPTION AND OPERATION Anti-Theft Alarm System NOTE: The system immediately monitors the ignition key lock cylinder upon removal of the key from the ignition. It is not necessary to arm the system for ignition key lock monitoring.

The anti-theft alarm system:
  • protects the vehicle from unauthorized entry into the passenger compartment, engine compartment and cargo area.
  • monitors the status of the ignition key lock cylinder.
  • is controlled by a remote anti-theft personality (RAP) module. The remote anti-theft personality module also controls the electronic door lock functions. Refer to Section 01-14B for more details.
  • when armed, detects unauthorized entry into the passenger compartment by using an input from the GEM module regarding the state of the door or liftgate (open or closed).
  • protects the engine compartment with a hood switch which is located on the LH cowl vent panel and is part of windshield wiper motor wiring (17A477) .
  • triggers an alarm if the ignition lock cylinder is forcibly removed from the steering column.
Once triggered, the system responds by:
  • flashing the low beam headlamps, the parklamps, rear lamps and the alarm indicator warning light emitting diode (LED).
  • sounding the horn (13832).
  • disabling the starter circuit until the system is disarmed.
---------------------------------------------------------------------------------------------
Remote Anti-Theft Personality Module
  • The remote anti-theft personality module is located behind the instrument panel (04320).
  • It contains a radio receiver that receives the RF signal from the keyless entry remote transmitter (15K601) through the alarm and lock system antenna (15603) and sends the appropriate command to the power door locks, the horn relay, or the generic electronic module.
  • The remote anti-theft personality module is equipped with an internal backup power supply which holds the programmed code in memory in the event the vehicle battery is disconnected.
-------------------------------------------------------------------------------
Remote Anti-Theft Personality Module Removal
  1. Disconnect battery ground cable (14301). Refer to Section 14-01 .
  1. Remove radio. Refer to Section 15-01 .

Components The system is composed of the following components:
  • remote anti-theft personality (RAP) module with integral antenna
  • alarm indicator LED
  • door lock cylinder switch RH, door lock cylinder switch LH
  • liftgate door lock cylinder switch (220A40)
  • hood switch (part of windshield wiper motor wiring (17A477))
  • ignition lock anti-theft switch (19A438)
The following vehicle components are also used by the anti-theft alarm system:
  • generic electronic module
  • power door lock switch (14028)
  • door open warning lamp switch (14018)
  • autolamp relay (14N089)
  • horn relay and bracket (13853) and horn (13832)
  • low beam headlamps
  • rear lamps (13404) and parking lamps (13200)
  • starter relay
  • door lock relays
  • keyless entry remote transmitter (15K601)
--------------------------------
Disarming an Untriggered System NOTE: A perimeter alarm will "shut off" after 165 seconds, but the system is still triggered and is not disarmed.

An armed but untriggered perimeter anti-theft system can be disarmed by one of the following four events:
  1. Unlock the doors by pressing the keyless entry remote transmitter (15K601) UNLOCK button once.
  2. Unlock any door with a key.
  3. Turn ignition switch to RUN or ACC.
  4. The remote entry PANIC button will disarm the anti-theft system only when the perimeter alarm is triggered and sounding.
------------------------------------------------
System Triggering NOTE: Although the remote entry PANIC alarm is not associated with the monitoring of the vehicle, the user will frequently say that the theft system was triggered when actually the keyless entry remote transmitter PANIC button was inadvertently pressed. A panic alarm will not flash the THEFT indicator.

The alarm can be triggered by the following events if the system has been armed and has not been disarmed first:
  • Open any door or liftgate.
  • Open the hood (16612) (if the hood was open when the system was armed, it must be closed before it can trigger the alarm).
  • Dislodge the ignition key lock cylinder.
  • The anti-theft system may be triggered inadvertently when the module is disconnected and then reconnected. To avoid inadvertent alarm triggering, disconnect the smaller 22-way connector first.
When the system is triggered the perimeter alarm will operate as follows: The remote anti-theft personality module will pulse the following outputs at approximately 1.3 Hz, 50 percent duty cycle for two minutes 45 seconds for North America. NOTE: Other perimeter alarms can be programmed for the system.

  • low beam headlamps
  • parking lamps
  • horn
  • THEFT indicator
The perimeter alarm can be retriggered, after a perimeter alarm has sounded for 165 seconds. After a perimeter alarm has timed out, if any trigger input is first seen as normal and is then seen in its trigger state, the perimeter alarm will be retriggered. The perimeter alarm can be triggered a total of three times between an arming sequence and a disarm event. An active panic alarm will be deactivated when a perimeter alarm is triggered (a perimeter alarm overrides a panic alarm).
