Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to avoid electrical hazards while working on the sensor system.

2. Clean the Sensors

Locate the front-facing camera and sensors, usually mounted near the rearview mirror or front grille.
Use a soft microfiber cloth and a mild cleaning solution to gently clean the camera and sensor lenses.
Rinse the cloth frequently to avoid scratching the lenses.

3. Check and Adjust Calibration

Reconnect the battery and turn on the ignition without starting the engine.
Access the vehicle settings menu using the infotainment system or dashboard controls.
Navigate to the "Driver Assistance" or "Lane Departure Warning" settings.
Follow the prompts to recalibrate the system as per the manufacturer’s instructions.

4. Inspect for Damage

If issues persist, visually inspect the wiring and connectors leading to the camera and sensors for any signs of wear or corrosion.
Replace any damaged wiring or connectors found during the inspection.

5. Professional Alignment Check

If false warnings continue, take the vehicle to an authorized service center for a professional wheel alignment check.
Ensure that alignment values are adjusted to meet Ford’s specifications.
