Solution

1. Battery Inspection

Sub-steps:
1. Ensure the vehicle is in park or neutral and the ignition is off.
2. Disconnect the negative (-) battery terminal using a socket wrench.
3. Clean any corrosion from the battery terminals using a wire brush.
4. Reconnect the negative battery terminal and tighten it securely.

2. Starter Motor Testing

Sub-steps:
1. Disconnect the positive (+) battery terminal.
2. Locate the starter motor, typically situated near the engine block.
3. Inspect wiring for damage and ensure connections are tight.
4. Use a multimeter to test for voltage at the starter motor while a helper turns the ignition to the start position.
5. If no voltage is present, further diagnose the ignition switch and wiring.

3. Starter Replacement (if necessary)

Sub-steps:
1. Ensure the vehicle is safely raised and supported on jack stands.
2. Disconnect the battery terminals (negative first, then positive).
3. Remove any components obstructing access to the starter (air intake duct, etc.).
4. Unbolt the starter motor from the engine block using the appropriate socket.
