Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, jumper cables.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery to prevent electrical shorts.

2. Battery Inspection and Replacement

Check Battery Voltage:
- Use a multimeter to measure the battery voltage. If below 12.6 volts, proceed to jump-start or replace the battery.
Clean Battery Terminals:
- Disconnect the negative terminal first, followed by the positive. Clean any corrosion using a wire brush and baking soda solution.
Reconnect Battery:
- Reconnect the positive terminal first, then the negative.
Replace Battery (if necessary):
- If battery is faulty, remove it using a socket set, install the new battery, and secure it properly.

3. Starter Motor Inspection

Test Starter Operation:
- Use jumper cables to bypass the starter. Connect the positive terminal of the battery to the starter solenoid terminal and the negative to the starter housing.
- If the starter engages, it may be defective; replace the starter motor.

4. Ignition Switch Inspection

Check Ignition Switch:
- Remove the steering column cover using a socket set.
- Test the ignition switch for continuity when turned to the start position.
- Replace the ignition switch if it fails the continuity test.

5. Final Checks

Inspect Fuses:
- Locate the fuse box and check the starting system fuses. Replace any blown fuses.
Scan for Error Codes:
- Use the OBD-II scanner to check for any diagnostic trouble codes that may indicate further issues.
