Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic socket set, and screwdrivers.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect Door Latches

Remove the door panel using a socket set and screwdriver to access the latch mechanism.
Check for proper operation of the latch and that it clicks securely when closed.
Clean any debris or corrosion from the latch and apply a suitable lubricant to ensure smooth operation.

3. Test and Replace Door Switch

Locate the door switch on each door frame.
Manually press the switch while observing if the dashboard light changes; if it doesn’t, the switch may need replacing.
Disconnect the old switch and install a new one by reversing the removal process.
Ensure the new switch is seated properly and functions correctly.

4. Check Wiring and Connections

Inspect the wiring harness connected to each door switch for fraying or damage.
Use a multimeter to check for continuity in the wiring; repair or replace any damaged wires as necessary.
Ensure all connections are secure and free from corrosion.

5. Reconnect Battery and Test

Reconnect the vehicle battery after all repairs and checks are complete.
Start the vehicle and check the dashboard for the "door ajar" warning light.
Cycle through each door to ensure the warning light activates and deactivates appropriately.
