Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, OBD-II scanner, and cleaning supplies.
Ensure the vehicle is in a safe, well-ventilated area and parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Battery Connections

Remove the positive battery terminal first, then the negative terminal.
Clean the battery terminals and cable ends with a wire brush to remove corrosion.
Reconnect the battery terminals, starting with the positive terminal followed by the negative terminal.

3. Test and Replace the Battery (if necessary)

Reconnect the multimeter to the battery; if the voltage is below 12.4 volts, proceed to replace the battery.
Remove the battery using the socket set; unbolt the battery hold-down bracket.
Install the new battery in reverse order, ensuring all connections are tight and secure.

4. Inspect and Test the Starter Motor

Locate the starter motor; typically found near the engine block.
Check the wiring and connections for damage or corrosion.
If necessary, remove the starter motor using the socket set and inspect it for functionality.
Replace the starter motor if it fails the bench test or shows signs of wear.

5. Recheck the System

Reconnect the battery and attempt to start the vehicle.
If the vehicle still does not start, further diagnosis may be required for the ignition switch or fuses.
