Solution

1. Preparation

Gather tools and materials.
Tools Required: Multimeter, OBD-II scanner, screwdrivers, socket set.
Safety Warnings: Ensure the vehicle is turned off and keys are removed from the ignition.

2. Door Inspection

Open each door one at a time and inspect the door latch mechanism.
- Check for any obstructions preventing the door from closing completely.
- Lubricate the latch mechanism if needed.
Close the doors and observe if the lights turn off.

3. Check Door Switch Sensors

Locate the door switch sensors (usually located in the door frame).
Disconnect the wiring harness from each door switch.
Use a multimeter to test for continuity:
- Connect the multimeter leads to the switch terminals.
- Check if the circuit is open when the door is closed and closed when the door is open.
Replace any faulty door switch sensors.

4. Inspect Light Control Switch

Locate the interior light control switch (commonly on the overhead console).
Ensure it is set to the 'off' position.
If problems persist, remove the switch and test for functionality using a multimeter.
Replace the switch if it is faulty.

5. Reassemble and Test
