Solution

1. Preparation

Tools Required: Multimeter, socket set, wrench set, wire brush, safety goggles, gloves.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Battery Inspection

Clean battery terminals using a wire brush to remove corrosion.
Tighten any loose connections at the battery.
If the battery voltage is low (below 12.4 volts), recharge or replace the battery as needed.

3. Starter Relay Replacement

Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
Remove the starter relay by pulling it straight out of the socket.
Replace with a new or known good relay.

4. Starter Motor Inspection

If clicking persists, locate the starter motor (typically found near the engine and transmission junction).
Disconnect the electrical connector from the starter motor.
Use a socket set to remove the mounting bolts and take out the starter motor for inspection.
Check for physical damage or wear on the starter motor.

5. Reinstallation

If the starter motor is functional, reattach it by reversing the removal steps and ensuring all bolts are tightened to the manufacturer’s specifications.
Reconnect the electrical connector to the starter motor.

6. Final Assembly

Reconnect the negative battery terminal.
Start the vehicle to check if the clicking noise is resolved.
