Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect Door Latch and Striker Plate

Open the affected door and examine the latch mechanism and striker plate.
Adjust the striker plate if misaligned using a socket set.
Ensure the door closes firmly against the latch without gaps.

3. Test and Replace Door Ajar Switch

Locate the door ajar switch, typically found within the door latch assembly.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity; if there is no continuity when the door is closed, replace the switch.
To replace, unscrew the old switch, install the new switch, and reconnect the wiring harness.

4. Inspect Wiring Harness

Visually inspect the wiring harness for any signs of wear, fraying, or disconnections.
If damage is found, repair or replace the wiring as necessary using electrical tape or heat-shrink tubing.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Close all doors and start the vehicle.
Check if the "door ajar" warning light is extinguished and if the central locking system functions properly.
