Solution

1. Preparation

Gather tools including a multimeter, socket set, and safety gloves.
Ensure the vehicle is in a safe working area and the ignition is off.

2. Battery Inspection and Replacement

Inspect Battery Connections:
- Disconnect the negative terminal of the battery first to prevent any electrical short.
- Clean any corrosion from battery terminals using a wire brush.
- Reconnect the terminals securely and ensure they are tight.
Test and Replace Battery if Necessary:
- If the battery voltage is below 12.4 volts, charge the battery or replace it.
- Install the new battery, ensuring correct polarity (positive to positive, negative to negative).

3. Starter Relay and Motor Inspection

Check Starter Relay:
- Locate the starter relay in the fuse box.
- Swap it with a similar relay to test if the relay is faulty.
Inspect Starter Motor:
- If the clicking persists, remove the starter motor using a socket set.
- Inspect for any loose connections or damage to the starter motor itself.
- Test the starter by applying direct battery voltage; if it does not engage, replace the starter motor.

4. Final Assembly

Reinstall the starter motor, ensuring all bolts are torqued to manufacturer specifications.
Reconnect the battery terminals, starting with the positive terminal, then the negative.
Ensure all tools are removed from the engine bay before closing the hood.
