Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wrench set
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Inspect and Clean Battery Connections

Sub-steps:
1. Remove the negative (-) battery terminal using a socket wrench.
2. Inspect the terminal for corrosion; clean it using a wire brush if necessary.
3. Reconnect the negative terminal securely.

3. Resetting the Battery Light

Sub-steps:
1. Reconnect the negative battery terminal and ensure it is tight.
2. Start the vehicle and allow it to run for a few minutes.
3. If the battery light is still on, use the OBD-II scanner to clear any stored trouble codes.
4. Turn off the vehicle, then restart it to check if the battery light has reset.

4. Further Inspection (if necessary)

If the battery light remains illuminated after the reset:
1. Confirm that the battery and alternator are functioning correctly based on earlier diagnostic steps.
2. Replace any faulty components as indicated by diagnostic trouble codes or physical inspection results.
