1989 300e. The anti theft alarm went off while driving the car now the engine won't start. We shut the car off and locked and unlucked the doors several times. The alarm reset and we began driving again. A few minutes later it went off again. We repeated the above steps. Now the engine won't crank and every now and then the door locks try to lock on its own and the marker lights will flash about twice and hour. We tried disconnecting the battery and alarm module and letting is set. We hooked everything back up and the engine still will not start.

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

99 explorer alarm disables. Motor dies

Anti-theft system can keep vehicle from starting , Alarm is for vehicle content theft , open door without key alarm sounds (horns) ! PATS - passive anti theft system PATS enables and disables the engine from starting ,it will not cause the engine to die ! You have some other kind of problem ! If the vehicle engine doesn't turn over an red light on top of dash flashes fast ,then you have anti-theft system problem !
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.

How do i bypass the anti theft system in a 2002 Stratus

Unfortunately if you are referring to the factory anti-theft system - it will have to have computers replaced. Once the Engine Computer sees a Theft Alarm request it will remain there forever and it will shut down the fuel system until seeing an OK To Start from the Theft Alarm.
If it is after market alarm - find it and disconnect wiring - restore connections to original
does that help?
If you are having trouble with the system? Make sure the battery is good and fully charged. There are entry switches on the back side of the lock cylinders on both front doors (probably knocked off when the door is "Slim Jim'd") and the trunk lock.
If your battery is dead and you try to jump it - you will have to turn off the alarm again after hooking up the jumper

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.

VEHICLE WONT START

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.
Installation
  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).

    34bdf35.gif
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).
