Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set, and trim removal tools.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts while working.

2. Inspect and Test Door Switches

Sub-step 1: Remove the door panel using trim removal tools to access the door switch.
Sub-step 2: Disconnect the wiring harness from the door switch.
Sub-step 3: Use a multimeter to test for continuity; ensure the switch is functioning properly (should have continuity when pressed).
Sub-step 4: If defective, replace the door switch with a new one.

3. Check Door Latch Mechanism

Sub-step 1: Inspect the latch mechanism for dirt, corrosion, or mechanical failure.
Sub-step 2: Clean the latch with a suitable cleaner and lubricate it with white lithium grease.
Sub-step 3: If the latch is damaged, replace it with a new one.

4. Door Alignment Adjustment

Sub-step 1: Visually inspect the alignment of the door; it should be flush with the body of the vehicle.
Sub-step 2: If the door is misaligned, loosen the hinge bolts and adjust the door position.
Sub-step 3: Retighten the hinge bolts to the manufacturer's torque specification (usually around 10-15 Nm).

5. Reassemble and Test

Sub-step 1: Reconnect the door switch wiring harness and reattach the door panel.
Sub-step 2: Reconnect the battery and check if the door ajar warning has cleared.
Sub-step 3: Perform a test drive to ensure that the warning does not reappear and that all doors lock and unlock correctly.
