Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-steps:
- Reconnect the negative terminal to the battery after confirming it is charged.
- Clean any corrosion from the terminals using a wire brush and a mixture of baking soda and water.
- Tighten the battery terminals securely.

3. Starter Motor Replacement (if needed)

Sub-steps:
- Raise the vehicle using jack stands and ensure it is secure.
- Disconnect the positive battery terminal.
- Remove any components blocking access to the starter (e.g., heat shield).
- Unbolt the starter motor from its mounting (typically 2-3 bolts).
- Disconnect the electrical connectors from the starter.
- Install the new starter motor by reversing the removal steps.
