1. Clean any corrosion from the battery terminals using a wire brush.
2. Tighten the terminal connections securely.
3. If the battery is weak or dead, remove it from the vehicle using a socket set.
4. Replace with a new battery, ensuring it matches the specifications of the original.
5. Reconnect the terminals, starting with the positive terminal followed by the negative terminal.

3. Starter Relay and Fuse Inspection

Sub-steps:
1. Locate the fuse box and remove the cover.
2. Identify the starter relay and the associated fuses.
3. Replace any blown fuses and the starter relay if necessary.
4. Reinstall the fuse box cover securely.

4. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor, usually situated near the engine block.
