DESCRIPTION AND OPERATION
The anti-theft protection system provides two types of vehicle protection. The first is designed to provide the vehicle with protection from unauthorized entry into the passenger compartment. The second monitors the status of the ignition switch lock cylinder (11582).
The system is controlled by an anti-theft alarm control (19A366). When armed, unauthorized entry into the vehicle is detected by lamp switches (13713) (located in the passenger compartment door jambs). In addition, the system triggers an alarm if the ignition switch lock cylinder is removed from the steering column.
NOTE: The system immediately monitors the ignition switch lock cylinder upon removal of the key from the ignition. It is not necessary to arm the system for monitoring ignition switch lock cylinder.
Once triggered, the system flashes the low beam headlamps, the parking lamps (13201), 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 off ignition switch and remove key.
NOTE: At this point the anti-theft system automatically monitors the ignition switch lock cylinder (11582). If the lock cylinder is removed, the anti-theft alarm will activate for 2 minutes and 45 seconds. To arm the system, follow remaining steps.
2. Close all doors (unlocked).
3. Press the LOCK button on a transmitter to lock doors. Alarm warning lamp will turn on.
4. Wait approximately 30 seconds for the anti-theft warning lamp to turn off.
The system will also be armed when the following input sequence is followed:
5. Turn off ignition switch and remove key.
6. Open a door. Alarm warning lamp will flash.
7. Lock doors with power door lock switches (14028). Alarm warning lamp will now glow steadily.
8. Close all doors.
9. Wait approximately 30 seconds for the anti-theft warning lamp to turn off.
Opening the driver or RH front 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.
- Unlock front door (20124) with a key.
- Unlock front door by pressing the UNLOCK button of a remote entry transmitter.
- If remaining in the vehicle, turn ignition switch to ON or ACC.
The rear door of Bronco is not tied in with the anti-theft system. Using the key on the rear door will not disarm or trigger the theft system.
System Triggering
The armed alarm system will be triggered if either of the following steps is taken.
- Any door is opened without using a key or a remote entry transmitter to unlock the door first. Opening the rear door on Bronco will not trigger the system.
- Removal of the ignition switch lock cylinder.
Disarming a Triggered System
Performing either of the following steps will disarm the triggered alarm system.
- Driver or RH front door is unlocked with a key.
- Driver's 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. The vehicle's starter circuit will remain disabled until the system is disarmed.
Components
The system is composed of the following components:
- Anti-theft control module (19A366)
- Anti-theft warning lamp
- Door key disarm switches (driver and passenger doors)
- Remote entry module (15K602)
- Ignition switch lock cylinder sensor (19A438)
The following components already exist on the vehicle and are also used in the anti-theft system:
- Power door lock switches
- Lamp switches (13713) (all doors except Bronco rear door)
- Remote entry transmitter
- Horn relay
- Low beam headlamps
- Parking lamps (13201)
- Starter relay
The alarm system operating sequences are designed to be passive; therefore, the system can be armed or disarmed when following normal vehicle exit and entry procedures.
PANIC Alarm Activation
1. Press the PANIC button of a remote keyless transmitter. The exterior lights and horn will flash for approximately four minutes or until:
a. the PANIC button is pressed again, or
b. the ignition switch lock cylinder (11582) is turned on.
The panic feature is controlled with the remote keyless entry module and is completely independent of the anti-theft system.
