Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, screwdriver set, and flashlight.
  • Disconnect the negative terminal of the battery to prevent electrical shorts.
2. Inspect Door Switches
  • Locate each door switch, typically found in the door frame.
  • Test each switch using a multimeter to ensure they are functioning correctly. A functioning switch should show continuity when pressed.
  • Replace any faulty switches with new ones.
3. Check and Adjust Light Settings
  • Locate the interior light switch on the dashboard.
  • Set the switch to "door" to allow lights to turn on and off with door openings.
  • Test the dimming feature to ensure it is working correctly.
4. Examine Wiring and Connections
  • Inspect the wiring harness connected to the door switches for any signs of wear, fraying, or corrosion.
  • Repair or replace any damaged wiring as necessary, ensuring all connections are secure.
5. Reset Body Control Module
  • Reconnect the battery terminal.
  • Use the OBD-II scanner to reset any fault codes in the body control module.
  • Monitor the system to confirm the lights function properly after reset.
