Solution

1. Preparation

Gather tools: Multimeter, jumper cables, socket set, hammer, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent accidental short circuits.

2. Battery Inspection and Replacement

Check Battery Voltage
- Reconnect the multimeter to the battery terminals.
- If voltage is below 12.4 volts, charge the battery or replace it if it's unable to hold a charge.
Clean Battery Terminals
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion using a mixture of baking soda and water and a wire brush.
- Reattach terminals securely.
Replace Battery (if necessary)
- If the battery is faulty, remove it using a socket set.
- Install a new battery of the same specifications.
- Reconnect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection

Check Starter Connections
- Locate the starter motor (usually near the engine block).
- Inspect the wiring and connections for any damage or looseness; tighten as necessary.
Test Starter Functionality
- If the starter is accessible, tap it with a hammer while an assistant turns the key to the start position.
- If the engine cranks, the starter may need replacement.
Replace Starter Motor (if necessary)
- Disconnect the battery again.
- Remove the starter motor using a socket set, noting the orientation of wires.
- Install a new starter motor, ensuring all connections are secure.
