Solution

1. Preparation

Tools Required: Torque wrench, socket set, multimeter, OBD-II scanner
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect Door Alignment

Open each door and visually inspect the hinges and latch for proper alignment.
If misaligned, adjust the door hinges using a socket set to ensure a proper fit.

3. Check Door Latch Mechanism

Remove the door panel using a socket set to access the latch mechanism.
Inspect the latch for foreign objects, debris, or signs of damage.
Clean the latch mechanism with a suitable cleaner and lubricate with a silicone-based lubricant.

4. Test Door Switch Sensors

Locate the door switch sensor, which is typically near the latch assembly.
Disconnect the sensor connector and use a multimeter to check for continuity when the door is closed.
If the sensor fails the test, replace it with a new one.

5. Reassemble and Test

Reinstall the door panel and ensure all clips and screws are secured.
Close the doors and check if the warning light is still illuminated.
If the issue persists, consider resetting the vehicle’s electronic control unit (ECU) using the OBD-II scanner.
