Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, torque wrench, new battery (if needed), and starter relay (if needed).
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery cover if applicable.
- Clean the terminals using a wire brush to remove any corrosion.
- Reconnect the battery terminals securely.
Replace Battery (if faulty):
- Use the socket set to remove the battery hold-down bracket and disconnect the positive terminal first, followed by the negative terminal.
- Carefully lift the old battery out and replace it with a new one, ensuring it is oriented correctly.
- Reconnect the positive terminal followed by the negative terminal and secure the hold-down bracket.

3. Starter Relay Replacement

Remove the Starter Relay:
- Locate the fuse box under the hood and identify the starter relay.
- Use your hand or a relay puller to remove the old relay.
Install New Relay:
- Insert the new relay into the same location, ensuring it is seated properly.

4. Starter Inspection (if necessary)

Inspect Starter Connections:
- If clicking persists, check the connections at the starter motor for tightness and corrosion.
Test the Starter:
- If accessible, use a multimeter to check for 12 volts at the starter solenoid while attempting to start. If no voltage is present, further diagnosis of wiring may be needed.
