Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and a replacement headlight bulb if needed.
  • Disconnect the vehicle battery to ensure safety while working on electrical components.
2. Inspect Headlight Switch
  • Remove the switch panel from the dashboard.
  • Check for any physical damage or loose connections.
  • If defective, replace the headlight switch.
3. Check and Replace Headlight Bulbs
  • Open the hood and locate the headlight assembly.
  • Remove the headlight assembly according to the manufacturer’s instructions.
  • Inspect the bulbs for filament breakage or discoloration.
  • Replace the bulbs with new ones of the same type (e.g., H11 for low beam, 9005 for high beam).
  • Reinstall the headlight assembly.
4. Test Voltage at Connector
  • Reconnect the battery.
  • Using a multimeter, set it to measure DC voltage.
  • Probe the headlight connector terminals while the headlight switch is on to check for voltage.
  • If voltage is absent, proceed to check the relay and fuse.
5. Inspect Relay and Fuse
  • Locate the fuse box and identify the headlight fuse (refer to the owner’s manual).
  • Remove the fuse and check for continuity using a multimeter.
  • If blown, replace it with a fuse of the same amperage.
  • Locate the headlight relay (usually in the fuse box) and replace it if necessary.
6. Final Checks
  • Reassemble any components removed during the process.
  • Reconnect the battery.
  • Test the headlights to ensure proper function.
