Solution

1. Preparation

Gather necessary tools and safety equipment.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery Inspection and Replacement

Use a multimeter to confirm battery voltage. If the voltage is below 12.4 volts, charge the battery or consider replacement.
If replacing the battery, remove the terminal connections (negative first, then positive).
Replace with a compatible battery and reconnect terminals (positive first, then negative).

3. Fuse Replacement

Locate the fuse box (usually under the dashboard or hood).
Identify the blown fuses using the diagram on the fuse box cover.
Replace any blown fuses with fuses of the same amperage.

4. Wiring and Ground Connection Repair

Inspect all accessible wiring for signs of wear, fraying, or damage.
Repair or replace damaged wiring using appropriate gauge wire.
Check and clean ground connections; reattach securely.

5. Testing and Final Checks

Reconnect the negative battery terminal.
Start the vehicle and check if all previously malfunctioning systems are operational.
Perform a final scan with the OBD-II scanner to ensure no new error codes are present.
