Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery negative terminal to ensure safety.
Gather tools: multimeter, socket set, wrench set, hammer, and cleaning brush.

2. Battery Inspection and Replacement

Remove Battery Terminals
- Use a wrench to disconnect the negative (-) terminal first, followed by the positive (+) terminal.
Inspect and Clean
- Check for corrosion on the terminals and clean with a wire brush if necessary.
Test Battery
- Use a multimeter to confirm voltage. If below 12.4 volts, charge or replace the battery.
Reinstall Battery
- Connect the positive (+) terminal first and then the negative (-) terminal.

3. Starter Motor Examination

Remove Starter Motor
- Disconnect electrical connections and mounting bolts using a socket set.
Inspect Starter Motor
- Check for any visible damage or wear. Test the solenoid operation if possible.
Replace Starter Motor (if necessary)
- Install a new or refurbished starter motor, ensuring all connections are secure and correctly mounted.

4. Final Checks

Reconnect the battery, ensuring all connections are tight and clean.
Attempt to start the vehicle to verify if the issue is resolved.
