Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a screwdriver.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Test Door Switches

Sub-steps:
1. Remove the door panel of each door using a screwdriver and socket set to access the door switch.
2. Disconnect the wiring harness from the door switch.
3. Use the multimeter to check for continuity on the switch when pressed. If there is no continuity, the switch is faulty and needs replacement.

3. Inspect Wiring and Connectors

Sub-steps:
1. Inspect the wiring harness connected to the door switches for any signs of wear, cuts, or corrosion.
2. Repair any damaged wires using electrical tape or splicing as necessary.
3. Reconnect the wiring harness and secure the door panel back in place.

4. Replace Faulty Switches (if necessary)

Sub-steps:
1. If any door switch was found faulty, remove the old switch by unscrewing it from the door.
2. Install the new switch by securing it in place with screws.
3. Reconnect the wiring harness to the new switch.

5. Reconnect Battery and Test

Sub-steps:
1. Reconnect the negative battery terminal.
2. Test each door to ensure the interior lights turn off when closed.
3. Verify that the "Door Ajar" warning light is no longer illuminated.
