Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Connections
- Remove the negative terminal first, followed by the positive terminal.
- Clean any corrosion with a wire brush and a solution of baking soda and water.
- Reconnect terminals securely.
Test Battery Voltage
- Use a multimeter to check the voltage.
- If below 12.4 volts, charge the battery or replace it if it cannot hold a charge.
Replace Battery (if necessary)
- Remove the old battery and replace it with a new battery of the same specifications (typically 12V, Group Size 35).
- Secure the new battery in place and connect the positive terminal first, then the negative terminal.

3. Starter System Inspection

Starter Relay Testing
- Access the fuse box and locate the starter relay.
- Swap the relay with another relay of the same type to see if the issue resolves.
Starter Motor Check
- If clicking persists, access the starter motor beneath the vehicle.
- Check for loose connections or damaged wires leading to the starter.
- If necessary, remove the starter motor and test it separately using jumper cables.
- Replace the starter motor if it fails to engage.

4. Final Steps

Reconnect the battery terminals after all checks and repairs.
Ensure all connections are tight and secure.
Perform a visual inspection of the engine bay for any other potential issues.
