Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, wrench set, hammer, cleaning brush for terminals
Ensure the vehicle is in park (for automatic) or neutral (for manual) and the parking brake is engaged.

2. Battery Inspection

Disconnect the negative (-) terminal of the battery to prevent any electrical issues.
Remove the battery from the vehicle using a wrench, and inspect for any signs of corrosion or damage.
Clean the battery terminals with a cleaning brush and apply terminal protector.
Reinstall the battery and reconnect the terminals securely.

3. Starter Motor Check

Locate the starter motor beneath the vehicle, typically near the transmission.
Remove any protective covers if necessary.
Tap the starter lightly with a hammer to free any sticking components.
Reconnect the battery and attempt to start the vehicle.

4. Replace Battery (if necessary)

If the battery voltage is low (below 12.6 volts), replace the battery with a new one of the same specification.
Parts Required: New battery (ensure it matches the original specifications).
Install the new battery by reversing the removal steps and secure it properly.

5. Reassemble and Test

Recheck all connections, ensuring they are tight.
Start the vehicle to confirm the repair was successful.
