Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect Door Latches

Open each door and inspect the latch mechanism for debris or damage.
Clean any dirt or obstructions from the latches.

3. Test Door Switch

Locate the door switch (usually found on the door frame).
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity when the switch is pressed; it should show continuity when the door is closed and none when open.

4. Replace Faulty Components

If the door switch is faulty, replace it:
- Remove the old switch by unscrewing or unclipping it.
- Install the new switch in the reverse order.
If wiring is damaged, repair or replace the affected sections.

5. Reconnect Battery

Reconnect the vehicle battery if it was disconnected during repairs.
Ensure all connections are secure.

6. Clear Error Codes

Use the OBD-II scanner to clear any previous error codes related to the door sensors.
Monitor the system to ensure the warning light does not reappear.
