Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, OBD-II scanner.
Ensure the vehicle is in a safe location with the ignition off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Battery Inspection

a. Check Battery Voltage
- Connect the multimeter to the battery terminals (positive to positive, negative to negative).
- If the voltage is below 12.4 volts, proceed to charge or replace the battery.
b. Clean and Secure Battery Terminals
- Remove the battery terminals using the socket set.
- Clean any corrosion with a wire brush and a mixture of baking soda and water.
- Reattach the terminals securely.

3. Starter Relay Check

a. Locate the Starter Relay
- Open the fuse box, typically located under the dashboard or near the engine compartment.
b. Swap the Relay
- Identify a similar relay (e.g., horn relay) and swap it with the starter relay.
- Attempt to start the vehicle again.

4. Starter Motor Inspection

a. Access the Starter
- Locate the starter motor, usually found near the engine near the transmission.
- Remove any covers or shields as necessary.
b. Inspect Connections
- Check wiring and connectors for fraying or corrosion.
- Tighten loose connections or replace damaged wiring as needed.

5. Final Check

Reconnect the negative battery terminal.
Attempt to start the vehicle again to see if the clicking noise persists.
