Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Tools Required: OBD-II scanner, multimeter, socket set, fuse puller.

2. Battery and Connections Inspection

Remove the battery terminals (negative first, then positive).
Clean the terminals and connectors with a wire brush.
Reconnect the battery terminals (positive first, then negative) and ensure they are tight.

3. Fuse Replacement

Identify the blown fuses from the inspection.
Use a fuse puller to remove the blown fuses.
Replace with fuses of the same amperage rating.
Confirm the fuse box cover is securely closed.

4. Ground Connections Repair

Locate all ground connections, especially near the battery and engine.
Remove any corroded ground wires and clean the contact points.
Replace any damaged ground wires with new ones.
Reattach ground connections securely.

5. Voltage Testing and Component Repair

Reconnect the battery and use a multimeter to test voltage at problematic components.
If components are not receiving power, trace the wiring to find breaks or shorts.
Repair or replace any damaged wiring as necessary.
