Solution

1. Preparation

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

2. Inspect and Clean Battery Connections

Open the hood and locate the battery.
Use a socket set to disconnect the negative battery terminal first, followed by the positive terminal.
Clean any corrosion from the battery terminals using a mixture of baking soda and water.
Reconnect the positive terminal first, then the negative terminal, ensuring they are tight.

3. Reset the Battery Light

Sit in the driver's seat and close all doors.
Insert the key fob into the ignition (if applicable) or ensure the vehicle is in "Run" mode.
Press the brake pedal and simultaneously press the accelerator pedal fully.
Hold both pedals for about 10 seconds until the battery light on the dashboard turns off.
Release the pedals and turn the ignition off, then back on to check if the light remains off.
