Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire brush (for cleaning), safety gloves.
Ensure the vehicle is parked on a flat surface and the engine is off before starting work.

2. Clean Battery Connections

Sub-steps:
1. Disconnect the negative battery terminal using a socket wrench.
2. Remove the positive terminal.
3. Use a wire brush to clean any corrosion from the terminals and cable connectors.
4. Reconnect the positive terminal followed by the negative terminal, ensuring they are tight.

3. Reset Battery Light

Sub-steps:
1. Turn the ignition to the "On" position without starting the engine.
2. Press the accelerator pedal three times within 10 seconds.
3. Turn the ignition off and then start the engine.
4. Check if the battery light is still illuminated.

4. Test Charging System

Sub-steps:
1. Reconnect the multimeter to the battery terminals.
2. Start the engine and read the voltage; it should be between 13.7 to 14.7 volts.
3. If the voltage is out of range, further inspection of the alternator and related components is necessary.
