Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Check Battery Condition
- Use a multimeter to measure voltage.
- If the voltage is below 12.4 volts, consider jump-starting or replacing the battery.
Clean Battery Terminals
- Use a wire brush to clean any corrosion from the battery terminals.
- Reconnect the battery terminals tightly.
Replace Battery (if necessary)
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Replace with a new battery of the same specifications (typically a Group 51R for Civic).
- Reconnect terminals, starting with the positive terminal, then negative.

3. Starter Motor Inspection

Access Starter Motor
- Raise the vehicle using a jack and secure it with jack stands.
- Locate the starter motor beneath the engine.
Test Starter Motor
- Disconnect the starter motor wiring harness.
- Use a multimeter to check for voltage at the starter terminal while someone turns the ignition key to the start position.
- If no voltage is present, the ignition switch or relay may need to be checked.
Replace Starter Motor (if necessary)
- Remove the mounting bolts of the starter motor using a socket set.
- Carefully pull the starter motor out and replace it with a new unit.
- Reconnect the wiring harness and secure the starter motor with mounting bolts.
