Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wrench set, battery terminal cleaner.
Disconnect the negative battery cable to ensure safety.

2. Battery Inspection

Remove the battery terminals (positive first, then negative).
Clean any corrosion on battery terminals and cable connectors using a battery terminal cleaner.
Reconnect the battery terminals securely.

3. Starter Relay Replacement

Locate the starter relay in the fuse box (consult the owner’s manual for specific location).
Remove the relay by gently pulling it out of its socket.
Replace it with a new or known good relay.
Reconnect the ignition and check if the clicking persists.

4. Starter Motor Inspection

If the clicking continues, locate the starter motor under the vehicle.
Remove the wires connected to the starter (note their positions).
Use a socket wrench to remove the bolts securing the starter to the engine.
Inspect the starter for signs of damage or wear; replace if necessary.

5. Reinstall and Test

Reconnect the wiring to the starter.
Reconnect the negative battery cable.
Attempt to start the vehicle again.
