Solution

1. Preparation

Gather necessary tools and components.
Ensure the vehicle is in park or neutral with the parking brake engaged.
Disconnect the negative battery cable to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery cover (if applicable).
2. Clean battery terminals using a wire brush to remove corrosion.
3. Tighten the battery terminals securely.
4. If the battery voltage is below 12.4 volts, replace the battery with a new one (ensure it meets OEM specifications).

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor (usually found near the transmission).
2. Disconnect the electrical connectors from the starter.
3. Inspect the wiring for any damage or wear.
4. If necessary, remove the starter motor using a socket set and inspect it for mechanical failures or wear.
5. Replace the starter motor if testing indicates it is faulty or if there are signs of wear.

4. Reassembly

Sub-steps:
1. Reconnect all electrical connectors securely.
2. Reinstall the starter motor and torque bolts to manufacturer specifications (typically around 20-30 lb-ft).
3. Reattach the battery terminals, ensuring they are secure.
4. Reinstall the battery cover.

5. Testing

Sub-steps:
1. Reconnect the negative battery cable and ensure that it is tight.
2. Start the vehicle to check for the clicking noise.
3. Monitor the dashboard for any warning lights.
