Question about 1998 Volvo S70

1 Answer

Alarm haywire, can't override anti-theft system or turn on car

I locked the doors using inside automatic locks when I exited car. Husband stayed in car for a while. When he exited a passenger door a while later, alarm sounded. As he sat in driver seat trying to do something to stop alarm, I put my key in door lock, thinking that would stop the alarm. Instead, my key got stuck in door. Key couldn't lock doors, duplicate key couldn't start car or stop alarm from ignition.

It's the holiday, everything's closed, yet I found a AAA guy on the street. He tried to override it by disconnecting battery. Didn't work. He forced key out of door. Now driver door won't lock, key won't go in it, car won't start, lights flash every time anyone attempts any of these things, oh, and now the alarm horn doesn't go off. Sounds like a country song.

We don't have the remote controls anymore. Thought? Thanks.

    My car 1998 s70 T5 did the same on morning of 04 Jan 2009. I unlocked the boot with the key and the alarm sounded. Car is immobilised, alarm can't shut and I got the car without remotes.

    Dealer service agent wants me to tow it in to do a diagnostic and possible repair. THis exercise will be high on the budget side.

    Any ideas will be appreciated before I pay lots of money to the dealers.

    I have the same exact problem with my 1999 SAAB 9-5. Except mine just goes off randomly. When I turn it on it say Check Alarm or ALarm Failure.

  • Anonymous Mar 17, 2014

    Sometimes the car will start right away. Other times the alarm will go off when I try and start it. It won't go off when I open the door, it'll go off when I turn the key to the "on" potion and try to start it. Why is this happening and how to I get it to stop?

How do I disarm anti theft device on a 2001 ford taurus

Press the unlock button on your vehicle's key fob to deactivate the alarm. If you've misplaced your remote for the car, use the PATS programmed key to unlock the driver's side door. Then, put the key in the ignition and turn the key to the "on" position. The vehicle's battery should be on, but the engine shouldn't be running.

  • 2 Locate the override button on the alarm box, beneath the driver's side of the dashboard. Press the button and hold it in until the alarm beeps one time. The LED light for the alarm should stop blinking, indicating the anti-theft system is disabled.

  • 3 To reset the vehicle's alarm, put the PATS programmed key in the ignition and turn the key to the "on" position. Press the override button. When the alarm resets, it chirps two times and the LED light begins blinking.

    Anti theft activates while the car is running leaving me locked in the car

    i dont think that these vehicles for this year automaticly lock themselves so you must be locking yourself in with the switch inside the vehicle ,Now is this antitheft device the factory immobilisor as i have never seen fault on our europeon models which makes me think that this is a after market device and as such if i am correct in this then i would get my side cutters out and remove the thing as this is the sort i fault i see a lot of on here with american cars ,i think its a viper auto start /alarm and they seem to give no end of problems judging by the questions.For the life of me i cannot understand why anyone would want to lock themselves in a car in case of an accident and someone outside couldnt get you out in a hurry ,But who am i to judge but our europeon models do not lock themselves and never give a problem with the alarm going off when driving in fact they are one of the better cars for not giving immobilisor problems ,the door lock with its peculiar rod at the back that breaks with great frequency is a pain but alarms ? never a problem

    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).
    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.
    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.
    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.

    I work for a garage and we have a 1998 mystique that wont start we were wondering if there was some sort of anti-theft systeme that we dont know about and also we would like to have the were abouts of the...

    Starting System
    The function of the starting system is to crank the engine at a speed fast enough to allow the engine to start. Heavy cables, connectors and switches are used in the system because of the large currents required.
    The starting system consists of a gear reduced starter motor, battery, remote control switch (ignition switch) and relay.
    Vehicles equipped with automatic transaxle have a transmission range sensor attached to the circuit which prevents operation of the starter motor unless NEUTRAL or PARK are selected.
    Vehicles equipped with a manual transaxle have a start inhibit switch in the starter control circuit, which prevents operation of the starter motor unless the clutch pedal is in the applied position.
    The anti - theft protection system provides protection from unauthorized entry into the passenger compartment.
    The system is controlled by an anti - theft alarm control. When armed, unauthorized entry into the vehicle is detected by lamp switches.
    Once triggered, the system flashes the headlamps, the parking lamps, the alarm indicator, and sounds the horn. In addition, the starter circuit is disabled to prevent starting the vehicle until the system is disarmed.
    System Arming
    The system will be armed by the remote entry transmitter when the following input sequence is followed:
    1. Turn the ignition switch off and remove the key.
    1. Close all doors (unlocked).
    1. Press the LOCK button on a transmitter to lock doors. Alarm warning lamp will turn on.
    1. Wait for the anti - theft warning lamp to turn off.
    The system will also be armed when the following input sequence is followed:
    1. Turn the ignition switch off and remove the key.
    1. Open a door. Alarm warning lamp will flash.
    1. Lock doors with power door switches. Alarm warning lamp will now glow steadily.
    1. Close all doors.
    1. Wait for the anti - theft warning lamp to turn off.
    Opening any door will activate the alarm after the alarm is armed.
    Disarming an Untriggered System
    The system can be disarmed by performing one of the following procedures.
    • Driver or RH front door is unlocked with a key.
    • Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
    • If remaining in the vehicle, turn the ignition switch to ON or ACC position.
    System Triggering
    The armed alarm system will be triggered if any door is opened without using a key or a remote entry transmitter to unlock the door first.
    Disarming a Triggered System
    Carry out either of the following steps will disarm the triggered alarm system.
    • Driver or RH front door is unlocked with a key.
    • Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
    Two minutes and 45 seconds after the system has been triggered, the horns and exterior lamps will shut off automatically. The system will then reset to an armed state and will trigger again if another intrusion occurs.
    Passive Anti-Theft System (PATS)
    The Passive Anti-Theft System (PATS), known as SecuriLock, is fully passive in operation and requires no special procedures by the driver to arm or disarm the system. It is invisible to normal scrutiny and is operated by a transponder within the key body. This communicates with the module through a transceiver mounted around the ignition switch lock barrel.
    The PATS functionality is incorporated within the powertrain control module.
    PATS keys contain an electronic device inside, and are physically larger than a non-PATS key.
    The transponder code reading is carried out when the key is inserted into the ignition lock barrel, and turned from position 0' to position II' or III' to crank the engine. If the PCM receives the correct code signal, the engine will start. Should the code received not be recognized, the engine will not crank as the PATS is still armed and the engine immobilized.
    Anti-Theft Indicator
    Whenever the ignition is switched on the anti-theft indicator will remain on for three seconds while the system carries out an initial ignition key-read.
    The anti-theft indicator will flash rapidly for three seconds to indicate the PATS has immobilized the vehicle.
    For additional information on the PATS fault codes, refer to the Diagnosis and Testing section.

    I got locked INSIDE my 2001 Lexus LX470 today. I

    This is the anti theft function working as it should. Your husband needed to override it with the key. The command told the car to lock down. Because the key was not in the car the anti theft set off the alarm and locked down the engine as well.
    This is exactly what you would want the car to do if you left it locked on the street with your windows down while shopping. Otherwise someone could reach in the window, unlock the door, slide in and start hot wiring the car.
    These lock functions are programmable and can be changed at the dealership.

    This is the problem due to your anti theft alarm system. You have not mentioned which brand of anti-theft alarm system you have? Anyhow, most of the systems have a reset switch inside the kit, open the kit and on the main board, u will find the reset button, press that and hold for 5 sec, the system will be reset. Otherwise, there are 2 or 3 fuses with the wiring of kit, remove those fuses and ur engine will wake up but the anti-theft system wont work then, hope this will solve the problem

    Button inside middle of the doors?

    The red button you are describing turns off the interior motion detector when you arm your anti-theft system. For example if you were to leave a pet in the car, it would turn off the interior motion detector. I don't recommend that you leave a pet in the car in hot weather or cold. But that is the function of that button. Also if you were to stay in the car and arm the anti-theft alarm it would keep you from setting off the detector that monitors motion inside the car. I don't know why you would want to arm the anti-theft alarm when you are inside the car, but you could if you wanted to. The next time you lock or unlock the car the interior motion detector will automatically be reactivated. Each time I use the remote to lock all the doors the alarm system is activated. I am not an expert, I have only had my 1998 Audi a4 2.8 for a week, so I am just learning about the car. Hope this helps. Vidar

    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 .
    1. Remove lower instrument panel center finish panel. Refer to Section 01-12 .
    1. Lower glove box.
    1. Remove two remote anti-theft personality module bracket retaining screws.
    1. Disconnect electrical connectors and alarm and lock system antenna (15603).
    1. Remove remote anti-theft personality module and bracket.
    1. Remove remote anti-theft personality module from mounting bracket.
    1. To install, follow removal procedure in reverse order.
    1. Tighten remote anti-theft personality module bracket retaining screws to 6-8 Nm (54-70 lb-in).

    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).
