Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrench set, and load tester.
Ensure the vehicle is parked on a flat surface and the engine is turned off.

2. Clean Battery Terminals

Disconnect the negative (-) battery terminal first, followed by the positive (+) terminal.
Clean the terminals and cable ends with a wire brush or terminal cleaner to remove corrosion.
Reconnect the positive (+) terminal first, then the negative (-) terminal.

3. Reset the Battery Light

Start the engine to see if the battery light remains illuminated.
If the light persists, turn off the engine and disconnect the negative battery terminal again.
Wait for 10-15 minutes before reconnecting the terminal to reset the vehicle’s computer.
Reconnect the negative terminal and start the engine again.

4. Inspect and Replace if Necessary

If the battery light is still on, inspect the alternator and battery for defects.
Replace the battery or alternator if they fail testing.
