Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Maintenance

Sub-steps:
1. Disconnect the negative battery terminal using a socket set.
2. Clean the battery terminals and cable ends with a wire brush to remove corrosion.
3. Reconnect the battery terminals securely, starting with the positive terminal followed by the negative.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor under the vehicle.
2. Disconnect the electrical connections from the starter motor.
3. Using jumper wires, connect the starter motor directly to the battery to see if it engages.
4. If the starter does not engage, replace the starter motor.

4. Ignition Switch and Relay Check
