Solution

1. Preparation

Gather tools and materials: multimeter, wrench set, screwdriver, safety gloves, and safety glasses.
Ensure the vehicle is in a safe, well-ventilated area.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery to prevent electrical shock.
2. Clean any corrosion from the battery terminals using a wire brush and baking soda solution.
3. Reconnect the battery terminals securely.

3. Starter Relay Check

Sub-steps:
1. Locate the starter relay in the fuse box.
2. Remove the relay and inspect for any damage or corrosion.
3. Swap it with a similar relay (ensure both are identical) to test functionality.

4. Starter Motor Testing

Sub-steps:
1. Disconnect the wiring harness from the starter motor.
2. Use a multimeter to check for voltage at the starter terminal when the ignition switch is turned on.
3. If voltage is present but the starter does not engage, it may need replacement.

5. Ignition Switch Inspection

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Test the ignition switch for continuity using a multimeter when turned to the start position.
3. Replace the ignition switch if it does not show continuity.
