Solution

1. Preparation

Gather tools and components: OBD-II scanner, multimeter, socket set, and replacement headlight bulbs.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Headlight Bulbs

Open the hood and locate the headlight assembly.
Remove the headlight bulb socket by twisting it counterclockwise.
Inspect the bulb for any signs of damage or discoloration.
Replace the bulb if necessary with a new one, ensuring it is securely seated.

3. Check Battery Connections

Disconnect the negative terminal of the battery using a socket set.
Inspect the battery terminals for corrosion; clean if necessary using a wire brush.
Reconnect the battery terminal and ensure it is tight and secure.

4. Test the Alternator

Start the engine and set the multimeter to the DC voltage setting.
Place the positive probe on the alternator output terminal and the negative probe on the engine ground.
The voltage should read between 13.5 to 14.5 volts; if not, the alternator may need replacement.

5. Examine Wiring Harness

Inspect the wiring harness connected to the headlights for any signs of wear or fraying.
Repair or replace damaged wiring as necessary.
Ensure all connectors are securely fastened.
