Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, safety gloves.
Disconnect the negative battery terminal to prevent electrical shock while working.

2. Inspect and Clean Battery Terminals

Sub-steps:
1. Remove the positive terminal first, followed by the negative terminal.
2. Clean the terminals and cable ends using a wire brush and a mixture of baking soda and water to remove corrosion.
3. Reconnect the terminals securely, starting with the positive terminal.

3. Test and Replace Battery (if necessary)

Sub-steps:
1. If the battery voltage is below 12.4 volts, charge the battery using a battery charger.
2. If the battery fails to hold a charge or is more than 3-5 years old, replace it with a new one.
3. Use a battery with the correct specifications as per the manufacturer's recommendations.

4. Check and Replace Alternator (if necessary)

Sub-steps:
1. If the alternator output voltage is outside the specified range, consider replacing the alternator.
2. Remove the serpentine belt by loosening the tensioner pulley.
3. Disconnect the electrical connectors and mounting bolts from the alternator.
4. Install the new alternator by reversing the removal steps, ensuring all connections are secure.

5. Finalize and Reconnect

Reconnect the negative battery terminal.
Start the engine to ensure the battery light is no longer illuminated.
