Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, wire brush or battery terminal cleaner.
Disconnect the negative terminal of the battery to ensure safety.

2. Inspect Battery Connections

Clean any corrosion on the battery terminals with a wire brush.
Tighten the battery terminal connections to ensure a good electrical connection.

3. Test the Starter Motor

Locate the starter motor underneath the vehicle.
Use a multimeter to check for voltage at the starter when the ignition key is turned to the start position.
If voltage is present but the starter does not engage, replace the starter motor.

4. Check Ignition Switch

Remove the steering column cover to access the ignition switch.
Test the ignition switch's continuity with a multimeter. Replace the switch if it fails to show continuity when turned to the start position.

5. Inspect Fuses

Locate the fuse box and check the fuses related to the starting system.
Replace any blown fuses and ensure the fuse connections are secure.
