Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery for safety.

2. Battery Inspection

Tools Required: Wrench set, wire brush, multimeter
Sub-steps:
1. Remove the negative terminal (black) followed by the positive terminal (red) from the battery.
2. Clean any corrosion from the battery terminals using a wire brush.
3. Ensure the terminals are tight and securely connected when reattaching.

3. Resetting the Battery Light

Tools Required: OBD-II scanner
Sub-steps:
1. Reconnect the battery terminals (positive first, then negative).
2. Start the vehicle and allow it to run for a few minutes.
3. Connect the OBD-II scanner to the vehicle's diagnostic port.
4. Navigate to the "Erase Codes" function on the scanner and select it to clear any error codes.
5. Disconnect the scanner and turn off the vehicle.

4. Final Checks

Start the vehicle again and check if the battery light is still illuminated.
If the light remains on, further investigation into the alternator and battery health may be necessary.
