Solution

1. Preparation

Gather tools: Multimeter, OBD-II scanner, flathead screwdriver.
Ensure the vehicle is off and take necessary safety precautions (e.g., disconnecting the battery).

2. Inspect Door Switches

Remove the door panel using a flathead screwdriver to access the door switch.
Disconnect the switch connector and test with a multimeter to ensure it opens and closes properly when the door is operated.
If faulty, replace the door switch with a new one.

3. Check Door Latches

Inspect each door latch for proper alignment and functionality.
Clean any debris or obstructions from the latch area that may prevent the door from closing securely.
Adjust or replace the latch if necessary, ensuring it engages properly when the door is closed.

4. Test Interior Light Switch

Locate the interior light switch (if applicable) and verify it is set to the "door" position.
If the switch is defective, replace it according to manufacturer specifications.
