Section 8 (Anti-Theft System): Description

1998 Mercury Mountaineer 5.0 P, AWDSECTION Description
WARNING: This page is about a different car, the 1997 Mercury Mountaineer and 1997 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

The anti-theft system is designed to prevent unauthorized entry into the passenger or engine compartment. When triggered, the system will provide audible and visual alarms. The horn will sound, and headlights, parking lights and alarm indicator will flash. In addition, the starter system will be disabled, preventing the vehicle from being started until the alarm system has been deactivated.

The system is controlled by a Remote Anti-Theft Personality (RAP) module. Whenever the system is armed, unauthorized entry will be detected by switches located in each door, a lock tamper detection switch at the liftgate lock cylinder, a hood switch, or the ignition key lock cylinder sensor. An alarm indicator is located on the instrument panel.
