Solution

1. Preparation

  • Gather tools: OBD-II scanner, multimeter, screwdriver set, and cleaning supplies.
  • Ensure the vehicle is parked safely with the ignition off.

2. Inspect Door Switches

  • Locate the door switches, which are typically found within the door frame.
  • Remove the door panel if necessary to access the switches.
  • Clean the switches and verify they are functioning correctly by pressing them manually.
  • Replace any faulty door switches.

3. Check Interior Light Settings

  • Start the vehicle and navigate to the driver’s information system.

  • Adjust settings if necessary and confirm that the lights respond accordingly.

4. Test Battery Voltage

  • Use a multimeter to measure the battery voltage.
  • A healthy battery should read around 12.6 volts when the vehicle is off.
