Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, and safety gloves.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to avoid electrical shocks.

2. Battery Inspection

Sub-step 1: Reconnect the battery terminal and test the voltage with a multimeter. If it reads below 12.4 volts, proceed to jump-start or replace the battery.
Sub-step 2: Clean the battery terminals with a wire brush if there is corrosion. Ensure the connections are tight.

3. Starter Relay Check

Sub-step 1: Locate the starter relay within the fuse box (refer to the owner's manual for exact location).
Sub-step 2: Swap the starter relay with another relay of the same type to test if the relay is faulty.
Sub-step 3: If the clicking noise persists, replace the starter relay with a new one.

4. Starter Motor Inspection

Sub-step 1: If the battery and relay are functioning, remove the starter motor from the engine (usually requires removing the battery and possibly the intake manifold).
Sub-step 2: Inspect the starter motor for signs of wear or damage. Use a multimeter to test for continuity and proper function.
Sub-step 3: If faulty, replace the starter motor with a new one.

5. Reassembly and Final Checks

Sub-step 1: Reinstall all components removed during the inspection and repair process.
Sub-step 2: Reconnect the negative battery terminal and ensure all connections are secure.
Sub-step 3: Attempt to start the vehicle to verify successful repair.
