Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather tools: OBD-II scanner, multimeter, wrench set, cleaning supplies (baking soda and water solution for corrosion).
Safety Warning: Disconnect the negative battery terminal before working on electrical components.

2. Addressing Battery Issues

Clean Battery Terminals
- Mix baking soda with water to form a paste.
- Use a wire brush to scrub the terminals and cable ends to remove corrosion.
- Rinse with water and dry thoroughly.
- Reconnect terminals securely.
Test and Replace Battery
- Using a multimeter, check the battery voltage. If it is below 12.4 volts, consider replacing the battery.
- If replacement is necessary, disconnect the terminals, remove the old battery, and install the new one, ensuring proper terminal connection (positive first, then negative).

3. Inspect and Replace Alternator (if necessary)

Inspect Alternator Belt
- Check for frays or cracks in the serpentine belt.
- Replace if damaged.
Remove Alternator
- Disconnect the negative battery terminal again.
- Remove the serpentine belt from the alternator.
- Unplug the electrical connector and remove the mounting bolts securing the alternator.
- Carefully lift the alternator out of the engine bay.
Install New Alternator
- Position the new alternator in place and secure it with mounting bolts.
- Reconnect the electrical connector and install the serpentine belt.
- Reconnect the negative battery terminal.

4. Reset Battery Light

After addressing any issues, start the vehicle.
If the battery light remains illuminated, use the OBD-II scanner to clear any stored codes that may be keeping the light on.
