Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather tools and parts necessary for the procedure.

2. Check Battery and Connections

Tools Required: Socket set, multimeter
Inspect battery terminals for corrosion. Clean terminals with a wire brush if needed.
Ensure battery cables are tightly connected. Re-tighten if loose.

3. Reset Battery Light

Tools Required: OBD-II scanner
Connect the OBD-II scanner to the vehicle's diagnostic port, typically located under the dashboard.
Turn the ignition key to the "On" position without starting the engine.
Follow the scanner's instructions to clear any trouble codes related to battery or charging system.
Disconnect the scanner after the codes are cleared.

4. Test Drive

Start the engine and check if the battery light has turned off.
Drive the vehicle for approximately 10-15 minutes to ensure that the warning light remains off.
