2. Inspect Battery Connections

Sub-step 1: Remove any corrosion from the battery terminals using a wire brush.
Sub-step 2: Tighten any loose battery connections securely.
Tools Required: Wire brush, wrench.

3. Check Battery Voltage

Sub-step 1: Reconnect the battery terminal.
Sub-step 2: Use a multimeter to measure the battery voltage. A healthy battery should read approximately 12.6 volts or higher.
Tools Required: Multimeter.

4. Test the Alternator

Sub-step 1: Start the engine and measure the voltage at the battery. It should be between 13.7 and 14.7 volts if the alternator is functioning properly.
Sub-step 2: If the voltage is outside this range, the alternator may need replacing.
Tools Required: Multimeter.

5. Reset the Battery Light

Sub-step 1: If all components are functioning well, use an OBD-II scanner to clear any DTCs that might be causing the battery light to stay on.
