Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdriver.
Ensure the vehicle is turned off and parked in a safe area.

2. Inspect Door Latches

Open each door and the trunk to inspect the latches.
Clean any dirt or debris from the latch mechanism and ensure it operates smoothly.
Adjust the latch position if misaligned to ensure proper closure.

3. Test Door Switches

Disconnect the battery to prevent any electrical shorts.
Locate the door ajar switches, usually mounted on the door frame.
Remove the switch by unscrewing it or pulling it out of its socket.
Use a multimeter to check for continuity:
- Press the switch and verify the multimeter reads continuity.
- If there is no continuity, replace the switch.

4. Inspect Wiring

Reconnect the battery and visually inspect the wiring harness connected to the door switches.
Look for any frayed wires, broken connections, or corrosion.
Repair or replace any damaged wiring as necessary.

5. Reassemble and Test

Reinstall any components removed during the inspection and testing.
Reconnect the battery and close all doors securely.
Start the vehicle and check if the door ajar light has turned off.
