Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal using a socket set.

2. Inspect and Clean Battery Terminals

Remove the positive battery terminal first, then the negative terminal.
Clean the terminals and cable ends using a wire brush and a battery terminal cleaner.
Reconnect the terminals, starting with the positive terminal first, followed by the negative terminal.

3. Check and Replace Battery (if necessary)

If the battery voltage is low or the battery is more than 3-5 years old, consider replacing it.
Remove the old battery by loosening the hold-down bracket and disconnecting the terminals.
Install the new battery, ensuring the correct orientation and connections.

4. Inspect and Replace Alternator (if necessary)

If the alternator is not charging the battery properly, it may need replacement.
Disconnect the negative battery terminal.
Remove the serpentine belt from the alternator by using a serpentine belt tool to relieve tension.
Disconnect the wiring harness from the alternator.
Remove the alternator mounting bolts and take out the alternator.
Install the new alternator by reversing the removal steps and reconnecting the battery.

5. Reset the Battery Light

Start the vehicle after completing repair procedures.
If the battery light remains illuminated, disconnect the negative battery terminal again for about 10 minutes to reset the system.
Reconnect the negative battery terminal and start the vehicle to check if the light is off.
