Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire brush, flashlight
Disconnect the negative terminal of the battery to prevent electrical shock or short circuits.

2. Inspect and Replace Headlight Bulbs

Remove the headlight housing by unscrewing the retaining screws.
Disconnect the wiring harness from the back of the headlight assembly.
Remove the old bulb by twisting it counterclockwise and replace it with a new bulb.
Reconnect the wiring harness and reinstall the headlight housing.

3. Clean Battery Terminals

Use a wire brush to clean any corrosion from the battery terminals.
Reconnect the battery terminals ensuring they are tight.
Apply a thin layer of petroleum jelly to the terminals to prevent future corrosion.

4. Check and Replace Fuses

Locate the fuse box and find the fuse associated with the headlights (refer to the owner's manual for the exact location).
Pull the fuse out using a fuse puller and inspect it for continuity.
Replace the blown fuse with one of the same amperage.

5. Test and Replace Headlight Relay

Locate the headlight relay in the fuse box.
Remove the relay and test it using a multimeter to ensure it is functioning (check for continuity).
If faulty, replace the relay with a new one.

6. Inspect Wiring Harness

Visually inspect the wiring harness for any signs of fraying, damage, or corrosion.
Repair any damaged wires with electrical tape or replace the entire harness if severely damaged.
