1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdrivers, pliers).
Disconnect the battery negative terminal to prevent any electrical shock or further damage.

2. Repair Damaged Wiring

Identify Faulty Wires: Based on the visual inspection, locate any damaged or frayed wires.
Cut the Damaged Section: Use wire cutters to remove the damaged portion of the wire.
Strip Insulation: Strip about 1/2 inch of insulation from both ends of the cut wire.
Reconnect Wires: Use heat-shrink connectors or solder the wires back together, ensuring a secure connection.
Insulate Repaired Area: Wrap the repaired section with electrical tape or heat-shrink tubing to prevent future exposure.

3. Replace Blown Fuses

Locate Fuse Box: Identify the vehicle's fuse box location (refer to the owner’s manual if necessary).
Remove and Inspect Fuses: Pull out any blown fuses using a fuse puller or pliers.
Install New Fuses: Replace with the correct amperage fuses as specified in the owner’s manual.
