Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver, OBD-II scanner.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent accidental short circuits.

2. Battery Inspection

Sub-steps:
1. Reconnect the battery and check voltage with the multimeter; it should read above 12.4 volts.
2. Clean any corrosion from the battery terminals using a wire brush and a solution of baking soda and water.
3. Tighten the battery terminals securely.

3. Starter Relay Testing

Sub-steps:
1. Locate the starter relay in the fuse box (refer to the owner’s manual for the exact location).
2. Swap it with a similar relay (e.g., horn relay) to test if the relay is faulty.
3. If the vehicle starts, replace the faulty starter relay.

4. Starter Motor Replacement (if necessary)

Sub-steps:
1. If the clicking noise persists, disconnect the negative battery terminal again.
2. Remove the starter motor by loosening the mounting bolts and disconnecting the electrical connectors.
3. Install the new starter motor, ensuring it is secured with the correct torque specifications (typically 15-25 lb-ft).
4. Reconnect the electrical connectors and negative battery terminal.
