Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, wrenches)
Safety Warnings: Disconnect the negative terminal of the battery before starting work on the electrical system.

2. Inspect and Clean Battery Connections

Disconnect the negative terminal using a wrench.
Inspect the positive and negative terminals for corrosion or damage.
Clean the terminals and battery posts using a battery terminal cleaner or a mixture of baking soda and water.
Reconnect the terminals securely, ensuring a tight fit.

3. Reset Battery Management System

Reconnect the negative battery terminal securely.
Insert the key into the ignition and turn it to the "ON" position without starting the engine.
Wait for about 10 seconds, then turn the key back to the "OFF" position.
Start the vehicle normally and observe if the battery light remains illuminated.

4. Test Electrical System

Use the multimeter to measure the voltage at the battery terminals while the engine is running.
Voltage should be between 13.7 to 14.7 volts if the alternator is functioning correctly.
If the voltage is low, further diagnose the alternator and wiring.
