Ford Focus Mk3 Interior Alarm Motion Sensor Control Unit Module AV6N-15K607-AE

Ford Focus Mk3 Interior Alarm Motion Sensor Control Unit Module is an original security system component responsible for precise motion detection within the vehicle cabin. This specialized control module works with the factory alarm, increasing the level of interior protection and responding to unwanted breaches of the passenger space. Thanks to its design compliant with Ford standards, it ensures consistent operation with other vehicle electronic components.

Purpose and function in the alarm system

The presented interior alarm motion sensor is a component of the Lidar and radar sensors category, responsible for monitoring the cabin space in the Ford Focus Mk3. The module analyzes changes in the vehicle's interior environment and sends a signal to the alarm controller when it detects movement or a breach of the protected zone. In practice, this means that once the alarm is armed, the sensor monitors the vehicle's interior, supporting protection against:

• unauthorized door or window opening,
• attempts to enter the cabin by breaking a window,
• unauthorized interference in the passenger space. Thanks to factory integration with the Ford Focus Mk3 electrical system, the module works with the existing alarm system architecture without the need for additional adapters.

Control module construction and vehicle integration

The motion sensor control module is designed as an OEM component, matched to the specific requirements of the Focus Mk3 platform. The appropriate housing geometry and connector placement facilitate installation in the location provided by the manufacturer, which helps maintain correct motion detection characteristics. Key design features include:

• a dedicated electrical connector, allowing for a secure connection to the vehicle's wiring harness,
• control logic designed for a specific model, ensuring compatibility with the factory alarm,
• a housing adapted for operation in car interior conditions (temperature changes, vibrations, typical operational loads). As a result, the sensor maintains stable operating parameters and can be used as a replacement for the factory-installed component without interfering with the original installation.

Benefits of using an original motion sensor

Using an original motion sensor control module in the Ford Focus Mk3 allows for maintaining the consistency of the entire security system. Factory fitment reduces the risk of communication errors with other controllers and minimizes problems with false alarm triggers. The most important advantages include:

• maintaining the sensitivity and detection characteristics intended by the manufacturer,
• no need for modifications to electrical harnesses or software,
• consistency with other vehicle security system components. In the case of windshield replacement or interference with the headliner, a properly functioning interior motion sensor is essential for maintaining full alarm functionality. It is worth paying attention to the correct seating of the module and its stable connection to the installation.

Component condition and installation aspects

The offered interior alarm motion sensor comes from the Ford group and is intended for re-installation in a vehicle, following prior verification of compatibility with the specific equipment version of the Focus Mk3. Before installation, it is recommended to check the alarm system configuration and compare the used module with the component currently installed in the car. During installation, it is worth paying attention to:

• correct routing of the electrical harness,
• stable mounting of the module in the designated place,
• alarm operation test after completion of work (arming, simulation of interior breach). For users planning work related to the windshield or other elements associated with sensors and the alarm system, practical tips regarding the selection of original components and their installation may be useful, as described in the article Spider web on the windshield? Why it is better to choose a used original with the manufacturer's logo when replacing.

Expanding the security system in a Ford

If you are planning a comprehensive repair or upgrade of the electronic security zone in your Ford and need other components from the same group, such as additional detection modules, sensors monitoring the vehicle's surroundings, or elements supporting the operation of assistance systems, check the available parts in the Ford Lidar and radar sensors category.
