Solution

1. Preparation

Gather necessary tools (see below).
Ensure the vehicle is in park (automatic) or neutral (manual) and that the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Clean the battery terminals using a wire brush to remove corrosion.
Reconnect the battery terminals securely.
If the battery is weak (below 12.4 volts), replace it with a new battery of the same specifications (usually Group 51R or 24F for Honda).
- Tools Required: Wrench set, wire brush, safety goggles, gloves.
- Safety Warning: Always wear safety goggles and gloves when handling batteries. Ensure the area is well-ventilated.

3. Starter Relay Check

Locate the fuse box under the hood and identify the starter relay (refer to the owner's manual for the exact location).
Swap the starter relay with another identical relay from the fuse box.
Attempt to start the vehicle again.

4. Starter Motor Inspection

If the clicking continues, access the starter motor by removing any obstructing components (e.g., engine cover).
Inspect the starter motor wiring for damage or loose connections.
If necessary, remove the starter motor:
- Unscrew the bolts securing it to the transmission.
- Disconnect the electrical connector.
- Replace with a new or remanufactured starter if defective.
