Solution

1. Preparation

Ensure the vehicle is parked safely and powered on.
Gather necessary tools and replacement parts.
Disconnect the vehicle's 12V battery to prevent electrical shock.

2. Access the Frunk Latch Assembly

Remove the front trunk liner by unscrewing the retaining clips using a socket set.
Carefully pull back the liner to expose the latch mechanism and wiring.

3. Inspect and Clean the Latch Mechanism

Visually inspect the latch for any debris or obstructions.
If dirty, clean the latch and surrounding area with a suitable cleaner.
Check the latch alignment and ensure it is not bent or broken.

4. Test the Frunk Actuator

Reconnect the battery and test the frunk actuator by triggering the release button.
If the actuator does not operate, disconnect the connector and test for continuity using a multimeter.
Replace the actuator if it is not functioning properly.

5. Reassemble the Frunk Components

Once repairs or replacements are complete, reposition the liner and secure it with the retaining clips.
Ensure all components are securely fastened.

6. Final Test

Reconnect the vehicle's battery.
Test the frunk opening mechanism multiple times using the touchscreen, mobile app, and manual release.
