Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set, and wire brush.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Inspect and Replace Headlight Bulbs

Sub-step 1: Open the hood and locate the headlight assembly.
Sub-step 2: Remove the headlight assembly by unscrewing the retaining screws.
Sub-step 3: Disconnect the electrical connector from the bulb.
Sub-step 4: Remove the old bulb and replace it with a new, compatible headlight bulb (consult the owner’s manual for specifications).
Sub-step 5: Reconnect the electrical connector and reassemble the headlight assembly.

3. Check and Repair Wiring Harness

Sub-step 1: Inspect the wiring harness for any visible damage, such as fraying or corrosion.
Sub-step 2: Use a wire brush to clean any corroded connections.
Sub-step 3: Repair any damaged wires using heat-shrink tubing and solder, or replace the wiring harness if necessary.

4. Test and Replace the Headlight Relay

Sub-step 1: Locate the headlight relay in the fuse box (refer to the owner’s manual for the specific location).
Sub-step 2: Remove the relay and test it with a multimeter for continuity.
Sub-step 3: If the relay is faulty, replace it with a new one.

5. Battery and Charging System Check

Sub-step 1: Use a multimeter to check the battery voltage; it should be around 12.6 volts when the car is off.
Sub-step 2: Start the vehicle and measure the voltage again; it should be between 13.7 to 14.7 volts.
Sub-step 3: If the voltage is low, consider charging the battery or replacing it if necessary.
