Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean the battery terminals and cable ends with a wire brush to remove corrosion.
3. If the battery is weak (below 12.4 volts), charge it or replace it with a new battery.
4. Reconnect the battery terminals (positive first, then negative).

3. Starter Motor Inspection and Replacement

Sub-steps:
1. Locate the starter motor (typically found near the transmission).
2. Disconnect the wiring harness and remove the bolts securing the starter motor.
3. Carefully remove the starter motor from its housing.
4. Inspect the starter for any signs of wear or damage.
5. If necessary, replace the starter motor with a new one, ensuring it matches OEM specifications.
6. Reinstall the starter motor and reconnect the wiring harness.

4. Testing the System

Sub-steps:
1. Reconnect the negative battery terminal.
2. Attempt to start the engine to ensure it cranks and starts properly.
3. If the engine starts, monitor for any unusual noises or warning lights.
