Solution

1. Preparation

Gather necessary tools and ensure safety measures are in place.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Battery Connections

Remove the positive (+) and negative (-) battery cables.
Clean the terminals and cable ends with a wire brush to remove any corrosion.
Reattach the battery cables securely, ensuring a tight fit.

3. Test and Replace the Battery (if necessary)

If the battery voltage is below 12.4 volts, charge the battery using a battery charger.
If the battery is unable to hold a charge, replace it with a new one (ensure it meets OEM specifications).

4. Examine the Starter Motor

Locate the starter motor (usually near the engine block).
Using a socket set, remove the starter motor's mounting bolts.
Visually inspect for any damage or wear.

5. Replace the Starter Motor (if faulty)

Disconnect the electrical connectors from the starter motor.
Remove the starter motor from the vehicle.
Install the new starter motor by reversing the removal steps and tightening bolts to the manufacturer's torque specifications.

6. Reconnect the Battery

Reattach the negative battery terminal.
Ensure all connections are secure.
