Solution
1. Preparation
  • Gather tools and parts required for repair.
  • Disconnect the negative battery terminal to ensure safety.

Tools Required:

  • Multimeter
  • Socket set
  • Screwdriver set
  • OBD-II scanner
2. Inspect and Replace Bulbs
  • Remove the headlight assembly as per the service manual.
  • Inspect the headlight bulbs for any signs of burnout or damage.
  • Replace any faulty bulbs with OEM or high-quality aftermarket bulbs.
  • Reinstall the headlight assembly and reconnect wiring.
3. Check and Replace Fuses/Relays
  • Locate the fuse box and identify the headlight fuses and relays.
  • Remove the fuses and visually inspect them for any blown elements.
  • Replace any blown fuses with the same amperage rating.
  • Test the relays by swapping with a known good relay if available.
4. Repair Wiring Connections
  • Inspect the wiring harness for any visible damage, fraying, or corrosion.
  • Clean any corroded connectors with electrical contact cleaner.
  • Repair or replace damaged wiring and ensure all connections are secure.
5. Test Electrical System
  • Reconnect the negative battery terminal.
  • Start the engine and use the multimeter to measure battery voltage; it should be around 13.7V - 14.7V with the engine running.
  • If voltage is low, inspect the alternator and charging system.
