Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's 12V battery to ensure safety while working on electronic components.

2. Inspect and Adjust Door Alignment

Open the door fully.
Use a socket set to loosen the hinge bolts slightly (do not remove them).
Adjust the door position until it is aligned with the body.
Tighten the hinge bolts to the manufacturer’s torque specifications (typically around 20-25 Nm).

3. Inspect and Clean the Door Latch

Remove any dirt or debris from the latch area using a soft cloth and appropriate cleaner.
Apply a small amount of lithium grease to the latch mechanism for smoother operation.

4. Test and Repair Electronic Components

Reconnect the battery and power on the vehicle.
Use the touchscreen to check if the door locking mechanism functions correctly.
If malfunctioning, access the door panel by removing screws and clips. Inspect wiring for frays or disconnections.
Replace any damaged wiring or connectors.

5. Replace Door Latch (if necessary)

If the latch is damaged, remove it by unscrewing it from the door.
Install the new latch in the reverse order of removal, ensuring it is securely fastened.
Test the latch operation by manually closing the door.
