Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Turn off the ignition and remove the key.
Gather tools: OBD-II scanner, multimeter, wrenches, and a socket set.

2. Address Underlying Issues

Battery Check:
1. Disconnect the negative terminal of the battery.
2. Remove the battery from the vehicle if necessary for testing.
3. Use a multimeter to test the battery; if it is below 12.4 volts, consider replacing it.
Alternator Check:
1. Reconnect the battery terminals after inspecting.
2. Start the engine and measure the voltage at the battery terminals; it should read between 13.7-14.7 volts.
3. If the reading is low, inspect the alternator for signs of failure and consider replacing it.

3. Resetting Battery Light

Using the OBD-II Scanner:
- Connect the OBD-II scanner to the vehicle's port.
- Turn the ignition to the "ON" position without starting the engine.
- Navigate to the "Clear Codes" option on the scanner and follow prompts to reset any battery-related fault codes.
Manual Reset (if applicable):
- Disconnect the negative battery terminal for about 5-10 minutes.
- Reconnect the terminal ensuring a tight fit.
- Start the vehicle to check if the battery light has reset.
