Solution
1. Preparation
  • Tools Required:
    • OBD-II scanner
    • Multimeter
    • Socket set
    • Screwdriver set
  • Ensure the vehicle is parked on a flat surface and the engine is off. Disconnect the battery before performing any electrical work.
2. Inspect and Replace Headlight Bulbs
  • Remove the headlight assembly using the socket set.
  • Disconnect the electrical connector from the back of the bulb.
  • Remove the old bulb, taking care not to touch the glass with bare hands.
  • Install a new bulb (ensure it is the correct type) and reconnect the electrical connector.
  • Reinstall the headlight assembly and reconnect the battery.
3. Check Wiring and Connections
  • Visually inspect the wiring harness leading to the headlights for any signs of wear, fraying, or corrosion.
  • Use the multimeter to check for voltage at the connector with the headlights turned on. The reading should be close to the battery voltage (approximately 12-14 volts).
  • Repair any damaged wiring or replace the connector if necessary.
4. Test the Headlight Control Module
  • If bulbs and wiring are intact, locate the headlight control module (usually found near the front of the vehicle).
  • Disconnect the module and visually inspect for water ingress or corrosion.
  • Use the multimeter to test the module for proper output voltage and functionality. Consult the service manual for specific voltage values.
  • Replace the headlight control module if it is faulty.
