Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, fuse puller, and wire strippers.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery and Connections

Clean the battery terminals using a wire brush to remove corrosion.
Tighten the battery cable connections to ensure a solid contact.
If the battery is weak or old (over 3-5 years), consider replacing it with a compatible unit.

3. Inspect and Replace Fuses

Open the fuse box and locate the relevant fuses for the malfunctioning systems.
Use a fuse puller to remove and inspect each fuse.
Replace any blown fuses with new ones of the same amperage rating.

4. Wiring Inspection

Visually inspect wiring harnesses for any signs of wear, fraying, or exposed wires.
Repair or replace damaged wiring as necessary, using appropriate connectors and electrical tape for insulation.

5. Alternator Testing

Reconnect the battery terminal.
Start the vehicle and measure the alternator output using a multimeter; it should read between 13.5V to 14.5V.
If the output is below this range, consider replacing the alternator.

6. Final Check

Reconnect all components and terminals that were disconnected during inspection.
Reconnect the negative battery terminal and ensure everything is secure.
Perform a system check to ensure all electrical components are functioning properly.
