Solution

1. Preparation

Gather tools: Multimeter, socket set, hammer, wire brush, safety gloves, and safety glasses.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Maintenance

Disconnect the negative terminal of the battery to prevent any electrical shorts.
Clean the battery terminals using a wire brush to remove any corrosion.
Reconnect the battery terminals securely, starting with the positive terminal first, then the negative terminal.

3. Starter Motor Inspection

If the clicking persists after checking the battery, locate the starter motor (usually near the engine block).
Tap the starter lightly with a hammer or a similar tool to free any stuck components.
Attempt to start the vehicle again. If it starts, the starter may need replacement.

4. Battery Replacement (if necessary)

If the battery voltage is below 12.4 volts, consider replacing the battery.
Remove the old battery by disconnecting the terminals (negative first, then positive).
Install the new battery, connecting the positive terminal first, followed by the negative.

5. Starter Replacement (if necessary)

If the starter is determined to be faulty, remove it by disconnecting the wiring harness and the mounting bolts.
Install the new starter by reversing the removal process, ensuring all connections are secure.
Torque the mounting bolts to the manufacturer's specifications (typically around 15-20 ft-lbs).
