Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, and screwdriver set.
Ensure the vehicle is turned off and parked safely. Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Door Switches

Locate the door switches for each door.
Use a multimeter to test the continuity of each switch; ensure they close when the door is closed.
If a switch is faulty, replace it with a new one.

3. Check Vehicle Settings

Reconnect the battery terminal and start the vehicle.
Access the vehicle control screen and navigate to the interior lights settings.
Ensure the settings are configured correctly (e.g., "Turn off lights after exit" is enabled).

4. Wiring Inspection

Turn off the vehicle and inspect the wiring harness connected to the interior lights.
Look for any visible signs of wear, fraying, or corrosion.
Repair or replace any damaged wiring as necessary.

5. Final Assembly

Once all checks and repairs are complete, reassemble any components that were removed.
Reconnect the negative battery terminal and ensure all tools are cleared from the vehicle.
