Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, jumper cables, and a new battery if needed.
Ensure vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal from the battery to prevent any short circuits.
Sub-step 2: Clean any corrosion from the battery terminals using a wire brush and a suitable cleaning solution.
Sub-step 3: Reconnect the terminals securely and retest battery voltage.

3. Starter Relay Testing

Sub-step 1: Locate the starter relay in the fuse box (refer to the owner's manual for location).
Sub-step 2: Remove the relay and inspect for any signs of damage.
Sub-step 3: Swap the starter relay with another identical relay from the fuse box.
Sub-step 4: Attempt to start the vehicle again.

4. Starter Motor Testing

Sub-step 1: If the clicking persists, locate the starter motor (usually near the transmission).
Sub-step 2: Disconnect the electrical connections to the starter.
Sub-step 3: Use jumper cables to connect the starter directly to the battery; observe if the starter engages.
Sub-step 4: If the starter does not engage, replace the starter motor.
