Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, penetrating oil (if needed)
Safety Warnings: Disconnect the battery before working on electrical components.

2. Inspect Door Latches

Open each door and visually inspect the latch mechanism for any obstruction or misalignment.
Manually operate the latch to ensure it moves smoothly; apply penetrating oil if necessary.
Close each door and listen for a solid click indicating the latch is secure.

3. Test Door Ajar Switch

Locate the door ajar switch on each door (usually integrated into the door latch).
Disconnect the wiring harness from the switch.
Use a multimeter to check the switch continuity; it should show continuity when the door is closed and no continuity when open.
If the switch is faulty, proceed to replace it.

4. Replace Faulty Components

If the switch is defective:
- Remove the faulty switch by unscrewing it from the latch assembly.
- Install the new switch by reversing the removal process.
- Reconnect the wiring harness.
If the wiring is damaged:
- Repair or replace any damaged wires using appropriate connectors and soldering techniques.

5. Reconnect Battery and Test

After completing repairs, reconnect the battery.
Test each door to ensure that the door ajar warning light turns off when all doors are closed.
