Sub-steps:
1. Remove the battery terminals from the battery.
2. Clean the terminals and cable ends with a wire brush or battery terminal cleaner.
3. Reattach the terminals securely.

3. Starter Motor Inspection/Replacement

Sub-steps:
1. Locate the starter motor (usually near the engine block).
2. Disconnect the battery.
3. Remove any covers or components blocking access to the starter.
4. Unplug the wiring harness from the starter.
5. Remove the mounting bolts with a socket set and take out the starter.
