Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, screwdriver set, and a flashlight.
  • Ensure the vehicle is in "off" mode and parked safely.
2. Inspect the Interior Light Switch
  • Locate the interior light switch, usually found on the overhead console.
  • Ensure it is set to "door" or "off" instead of "on."
  • If a mechanical fault is detected, replace the switch:
    • Remove the switch using a screwdriver.
    • Disconnect the wiring harness.
    • Install the new switch by reversing the process.
3. Check Door Sensors
  • Open each door and inspect the door latch mechanism for dirt or debris.
  • Press the door latch manually to simulate the door being closed and check if the lights turn off.
  • If a sensor is faulty:
    • Remove the door panel using a screwdriver.
    • Disconnect the wiring for the door sensor.
    • Replace the sensor if malfunctioning and reassemble the door panel.
4. Test the Interior Light Relay
  • Locate the fuse box, usually under the dashboard or in the engine compartment.
  • Identify the relay for the interior lights using the fuse diagram.
  • Test the relay with a multimeter for continuity.
  • Replace the relay if it shows signs of failure.
