Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire strippers, electrical tape, and a wiring diagram for the vehicle.
Ensure the vehicle is parked on a flat surface and the ignition is off before beginning work.
Disconnect the negative terminal of the battery to prevent any electrical shock or short circuits.

2. Repair Damaged Wiring

Identify Damaged Wires: Based on the visual inspection, locate any frayed or damaged wires.
Cut and Strip: Cut out the damaged section of the wire and strip the insulation from the ends to expose fresh wire.
Reconnect: Use solder or wire connectors to join the wires securely. Ensure connections are insulated with electrical tape to prevent exposure.

3. Clean Corroded Connections

Locate Corroded Areas: Identify any corroded terminals or connectors.
Clean Connections: Use a wire brush or sandpaper to remove corrosion. Follow up with electrical contact cleaner.
Reassemble: Reconnect cleaned terminals and apply dielectric grease to protect against future corrosion.

4. Replace Blown Fuses

Identify Fuse Ratings: Check the vehicle manual for the appropriate fuse ratings.
Replace Fuses: Remove blown fuses and insert new ones of the same rating into the fuse box.

5. Reconnect Battery

Reconnect the negative terminal of the battery after all repairs are complete.
Verify that all tools and materials are removed from the engine bay.
