Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdriver set.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Battery Terminals

Remove the battery terminals using a wrench.
Clean the terminals and battery posts with a wire brush to remove corrosion.
Reattach the terminals securely, ensuring a tight fit.

3. Replace Blown Fuses

Identify the blown fuses using the diagram on the fuse box cover.
Remove the blown fuses with a fuse puller or pliers.
Replace with new fuses of the same amperage rating.

4. Test and Replace the Alternator (if necessary)

Connect a multimeter to the battery terminals with the engine running.
Check the voltage; it should read between 13.7 to 14.7 volts.
If the voltage is outside this range, remove the alternator by:
- Disconnecting the wiring harness and the negative battery terminal.
- Removing the mounting bolts with a socket set.
- Installing a new alternator and reconnecting all wiring.

5. Repair or Replace Damaged Wiring

Inspect wiring harnesses for any frayed or exposed wires.
Use electrical tape to secure minor damage or replace sections of wire if needed.
Ensure all connectors are firmly attached and free from corrosion.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and test all electrical components for proper operation.
