Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery negative terminal to prevent electrical shorts during repairs.

2. Inspect and Test the Ignition Switch

Remove the steering column cover using a screwdriver.
Disconnect the ignition switch connector and visually inspect for damage or corrosion.
Use a multimeter to test the ignition switch for continuity in all positions (Off, On, Start).
Replace the ignition switch if faulty.

3. Examine Wiring and Relays

Inspect the wiring harness connected to the ignition switch for wear or damage.
Test the ignition relay by removing it and checking for continuity with a multimeter.
Replace any faulty wiring or relays as necessary.

4. Check the Engine Control Module (ECM)

Locate the ECM and check for any visible damage or loose connections.
Use the OBD-II scanner to check for software updates or faults in the ECM.
Reflash or replace the ECM if necessary.

5. Throttle Body and Idle Air Control Valve Inspection

Remove the air intake duct to access the throttle body.
Inspect the throttle body for carbon buildup or obstruction; clean with throttle body cleaner if needed.
Check the idle air control valve for proper operation and clean or replace as necessary.
