Tools Required:

OBD-II scanner
Multimeter
Socket set
Wrench set

2. Inspect and Clean Battery Connections

Sub-step 1: Remove the negative battery terminal using a wrench.
Sub-step 2: Inspect the terminal and cable for corrosion; clean with a mixture of baking soda and water if necessary.
Sub-step 3: Reattach the negative terminal securely.

3. Reset Battery Light

Sub-step 1: Reconnect the negative battery cable.
Sub-step 2: Start the engine and observe the dashboard for the battery light.
Sub-step 3: If the light remains on, use the OBD-II scanner to clear any error codes related to the charging system.

4. Test the Charging System

Sub-step 1: With the engine running, use a multimeter to check the voltage at the battery terminals; confirm it’s between 13.7V and 14.7V.
Sub-step 2: If the voltage is not within the range, further inspection of the alternator and related components may be needed.
