Solution

1. Preparation

Tools Required: Multimeter, wrench set, screwdriver, safety gloves, safety glasses.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Clean Battery Connections

Remove the positive (+) and negative (-) battery cables.
Inspect for any corrosion; clean terminals and cable ends with a wire brush.
Reconnect the battery cables securely.

3. Test and Replace Battery if Necessary

Use the multimeter to check the battery voltage again; if below 12.4 volts, charge the battery or replace it if it fails to hold a charge.
Ensure the battery is properly secured in place.

4. Check Starter Motor and Relay

Locate the starter relay in the fuse box.
Swap the starter relay with a similar relay to test if the initial relay is faulty.
If issues persist, remove the starter motor for inspection.

5. Remove and Inspect Starter Motor

Tools Required: Socket set, torque wrench.
Disconnect wiring harness from the starter motor.
Remove the mounting bolts using a socket set.
Inspect the starter motor for wear or damage; replace if needed.

6. Reinstallation

Reinstall the starter motor by reversing the removal steps.
Reconnect the wiring harness securely.
Reconnect the battery terminals; positive first, followed by negative.
