Solution

1. Preparation

Tools Needed: OBD-II scanner, multimeter, basic hand tools (screwdrivers, pliers), wire brush or terminal cleaner.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery Inspection

Remove the battery from the vehicle if corrosion is present.
Clean the terminals using a wire brush or terminal cleaner until shiny.
Reinstall the battery, ensuring a tight and secure connection.

3. Fuse Replacement

Open the fuse box and locate the specific fuse for the malfunctioning component.
Remove the blown fuse using fuse pullers or pliers.
Replace it with a new fuse of the same amperage rating.

4. Ground Connection Repair

Locate ground connections affected by corrosion or looseness.
Clean the connection points with a wire brush.
Tighten or replace any loose ground wires to ensure a solid connection.

5. Wiring Harness Repair

Inspect any damaged wiring visually; look for frays, breaks, or burn marks.
If damaged, repair using electrical tape or heat shrink tubing, or replace sections of the wiring harness as necessary.
