Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner.
Ensure the vehicle is in park and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Sub-step 1: Clean battery terminals with a battery terminal cleaner to remove corrosion.
Sub-step 2: Tighten loose connections on both the positive and negative terminals.
Sub-step 3: If the battery voltage is below 12.4 volts, recharge or replace the battery.

3. Starter Motor Inspection

Sub-step 1: Locate the starter motor; it is typically found near the transmission.
Sub-step 2: Inspect wiring connections to the starter; ensure they are secure and free from damage.
Sub-step 3: If the connections are intact, test the starter motor by applying direct voltage from the battery to see if it engages.

4. Relay and Fuse Check

Sub-step 1: Open the fuse box and locate the starter relay.
Sub-step 2: Swap the starter relay with another relay of the same type to see if the clicking noise persists.
Sub-step 3: Check the fuses related to the starting system to ensure they are intact.
