Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, battery terminal cleaner, and safety gloves.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-step 1: Use a multimeter to measure the battery voltage. If below 12.4 volts, charge or replace the battery.
Sub-step 2: Clean the battery terminals with a battery terminal cleaner or a mixture of baking soda and water, ensuring all corrosion is removed.
Sub-step 3: Reconnect the battery terminals securely.

3. Starter Relay Check

Sub-step 1: Locate the starter relay in the fuse box.
Sub-step 2: Remove the starter relay and check for continuity using a multimeter.
Sub-step 3: Replace the relay with a known good relay if faulty.

4. Starter Motor Inspection

Sub-step 1: Locate the starter motor and inspect the wiring and connections for any damage or looseness.
Sub-step 2: Use a wrench to secure any loose connections.
Sub-step 3: If necessary, remove the starter motor for testing or replacement.

5. Reassemble and Test

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Attempt to start the vehicle to check for the clicking noise.
