Solution

1. Preparation

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

2. Inspect and Clean Battery Connections

Sub-steps:
- Remove the battery terminals, starting with the negative terminal.
- Clean the terminals and the battery posts with a wire brush to remove corrosion.
- Reconnect the terminals securely, ensuring a tight fit.

3. Replace Blown Fuses

Sub-steps:
- Locate the fuse box (usually found under the dashboard or in the engine compartment).
- Identify any blown fuses by checking the fuse element or using a multimeter.
- Replace any blown fuses with the correct amperage rating.

4. Test and Replace the Battery (if necessary)

Sub-steps:
- Measure the battery voltage again; if it is below 12.4 volts, consider replacing the battery.
- Remove the old battery by disconnecting the terminals in reverse order (negative first).
- Install the new battery, connecting the positive terminal first followed by the negative.

5. Check and Replace the Alternator (if necessary)

Sub-steps:
- Test the alternator output using a multimeter; it should read between 13.8 to 14.4 volts while the engine is running.
- If the output is low, remove the alternator by disconnecting the battery, removing the serpentine belt, and unbolting the alternator from its bracket.
- Install a new alternator, reconnecting all electrical connections and the serpentine belt.
