Solution

1. Preparation

Gather tools: multimeter, socket set, and wrenches.
Ensure the vehicle is in park and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Battery Inspection

Visual Check: Inspect the battery for signs of corrosion or physical damage.
Clean Terminals: If corrosion is present, clean the terminals with a mixture of baking soda and water, and a wire brush.
Reconnect: Reconnect the battery terminals securely.

3. Starter Relay Replacement

Locate Relay: Identify the starter relay in the fuse box (refer to the owner's manual for specific location).
Remove Relay: Gently pull the relay out of the socket.
Install New Relay: Insert a new relay into the same socket; ensure it is firmly seated.

4. Starter and Ignition System Check

Starter Inspection: If the clicking persists, remove the starter motor (usually involves removing the heat shield and disconnecting wiring).
Test Starter: Test the starter with a multimeter; it should draw a significant voltage when engaged.
Replace Starter: If faulty, install a new starter motor, ensuring all connections are secure.
