Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire strippers, electrical tape, heat shrink tubing.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Repair Damaged Wiring

Identify Damaged Wires: Based on the visual inspection, locate any damaged sections of wiring.
Cut and Strip Wires: Use wire strippers to remove insulation from both ends of the damaged wire sections.
Splice Wires Together: Use solder or crimp connectors to join the wires securely.
Insulate Connections: Wrap the repaired sections with electrical tape or use heat shrink tubing to seal the connections.

3. Replace Blown Fuses

Locate Fuse Box: Identify the fuse box and the specific fuse related to the malfunctioning component.
Remove Blown Fuse: Use a fuse puller or pliers to extract the blown fuse.
Install New Fuse: Replace it with a new fuse of the same amperage rating.

4. Secure Ground Connections

Locate Ground Points: Find all ground points related to the electrical systems in question.
Clean and Tighten: Remove any corrosion and ensure that all ground connections are tight and secure.

5. Reconnect Battery and Test

Reconnect the Battery: Ensure that all tools are removed from the engine bay and reconnect the battery.
Test Functionality: Start the vehicle and check the functioning of the previously malfunctioning electrical components.
