2. Use a wrench to remove the screws securing the latch, then take the latch out for inspection.
3. Clean any debris or rust from the latch mechanism with a suitable solvent.
4. If the latch is damaged, replace it with a new one.
5. Reinstall the latch and ensure it aligns properly with the door striker.

4. Reconnect Battery and Test System

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the vehicle and check if the "door ajar" warning light has turned off.
3. Test each door by opening and closing them to confirm the warning light responds correctly.
