Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Multimeter, OBD-II scanner, screwdriver set, cleaning cloth.
Parts Required: Replacement door ajar switches (if necessary).
Ensure the vehicle is parked on a flat surface and the ignition is turned off.

2. Inspect Door Ajar Switches

Open each door and locate the door ajar switch (typically mounted in the door frame).
Disconnect the wiring harness from the switch.
Use a multimeter to test for continuity across the switch terminals while pressing the switch. A reading of zero ohms indicates a functioning switch.
If the switch does not show continuity when pressed, replace it with a new one.
Reconnect the wiring harness once repairs are complete.

3. Check Interior Light Control Settings

Start the vehicle and access the settings menu on the infotainment system.
Navigate to the "Lighting" or "Interior Lights" section.
Verify that the settings for automatic light control are appropriately set to turn off when doors are closed.
Make any necessary adjustments and save the settings.

4. Inspect Wiring Harness

Carefully examine the wiring harness leading to the door switches for any signs of wear, fraying, or corrosion.
If any damage is found, repair or replace the affected wiring as needed.
Ensure all connections are secure and free from moisture or debris.
