Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, load tester, wrench set, safety goggles, gloves.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery Terminal Cleaning

Sub-steps:
- Remove the positive and negative battery cables.
- Clean any corrosion from the terminals and cable ends using a wire brush and a mixture of baking soda and water.
- Rinse with water and dry thoroughly.

3. Battery Replacement (if necessary)

Sub-steps:
- If the battery fails the load test, remove the old battery by disconnecting the negative terminal first, followed by the positive terminal.
- Install the new battery in the reverse order: positive terminal first, then negative terminal.
- Ensure the battery is secured properly in the tray.
- Recheck the voltage with a multimeter to confirm proper installation.

4. Alternator Inspection

Sub-steps:
- If the alternator is suspected to be malfunctioning, remove the serpentine belt.
- Test the alternator output using a multimeter while it is running; ensure it falls within the specified voltage range.
- Replace the alternator if it fails to produce adequate voltage.

5. Final Check

Reconnect the negative battery terminal and ensure all connections are tight.
Start the vehicle and verify that all electrical components function correctly.
