Solution

1. Preparation

Gather tools: Multimeter, socket set, wrench set, battery terminal cleaner, safety gloves, and safety glasses.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Maintenance

Clean battery terminals using a battery terminal cleaner to remove any corrosion.
Tighten terminals to ensure a secure connection.
If the voltage is low, jump-start the vehicle or replace the battery if necessary.

3. Starter Relay and Fuse Inspection

Locate the starter relay in the fuse box; remove it using a socket.
Inspect the relay for continuity using a multimeter; replace if faulty.
Check the fuse related to the starter circuit and replace it if blown.

4. Starter Motor Inspection

Locate the starter motor; it is typically situated near the transmission.
Disconnect the wiring harness from the starter motor.
Remove the starter motor using the appropriate socket; note the mounting bolt torque specifications for reinstallation.
Test the starter motor directly by connecting it to a power source; replace if it does not operate.

5. Reassembly and Testing

Reinstall the starter motor and secure it with the correct torque.
Reconnect the wiring harness and battery terminals.
Reconnect the negative battery terminal.
