Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent any electrical shorts.
Gather necessary tools and replacement parts.

2. Battery Inspection and Replacement

Check Battery Condition
- Remove the battery from the vehicle if it is determined to be faulty.
- Clean the terminals with a wire brush to remove any corrosion.
Replace Battery (if necessary)
- If the battery is weak or dead, replace it with a new, fully charged battery (ensure it matches the specifications for the Honda Civic).
- Reconnect the terminals, first the positive and then the negative.

3. Starter Motor Inspection

Remove Starter Motor
- Locate the starter motor, usually found near the transmission.
- Disconnect the electrical connections from the starter.
- Unbolt the starter motor using a socket set and remove it from the vehicle.
Test Starter Motor
- Use a multimeter to check if the starter receives voltage when the ignition is turned on.
- If no voltage is present, the issue may lie in the ignition switch or wiring.
- If voltage is present but the starter does not engage, replace the starter motor.

4. Reassemble and Final Check

Reinstall the starter motor and reconnect all electrical connections.
Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay.
