Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, OBD-II scanner, safety gloves.
Disconnect the battery negative terminal to ensure safety while working.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion from battery terminals with a wire brush.
- Tighten battery terminal connections if they are loose.
Testing:
- Use a multimeter to check the battery voltage. If it is below 12.4 volts, charge or replace the battery.

3. Ignition Switch Testing

Access Ignition Switch:
- Remove the steering column cover using a screwdriver.
Test for Continuity:
- Disconnect the ignition switch and use the multimeter to check for continuity in the 'Start' position. If there is no continuity, replace the ignition switch.

4. Starter Motor Inspection

Locate Starter Motor:
- Access the starter motor under the vehicle, typically near the engine block.
Test Voltage:
- Use a multimeter to check for voltage at the starter terminal while someone attempts to start the vehicle. If no voltage is present, check the wiring and the ignition switch.
Replace Starter Motor:
- If voltage is present but the starter does not engage, remove the starter motor using a socket set and replace it with a new unit.

5. Reassembly and Final Steps

Reconnect all components and covers that were removed.
Reconnect the battery negative terminal.
Ensure all tools are removed from the engine compartment.
