Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire brush, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and the ignition is off before performing any electrical work.

2. Clean Battery Connections

Disconnect the negative terminal first, followed by the positive terminal.
Use a wire brush to clean any corrosion from the battery terminals and cable ends.
Reconnect the positive terminal first, then the negative terminal.

3. Replace Blown Fuses

Identify the location of the fuse box and the specific fuses related to the malfunctioning components.
Use the appropriate fuse puller to remove the blown fuses.
Replace with new fuses of the same amperage rating.

4. Repair or Replace Damaged Wiring

Inspect damaged wiring identified during diagnostics.
If damaged, either repair the wiring using appropriate gauge wire and connectors or replace the entire harness if necessary.
Use heat-shrink tubing or electrical tape to insulate any repairs.

5. Secure Ground Connections

Locate all ground connections under the hood and in the cabin.
Remove, clean, and re-tighten any loose ground connections to ensure proper conductivity.
