Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Record any error codes found and clear them if necessary.

3. Battery Inspection

Open the front trunk and check the main battery connections.
Ensure all terminals are tight and free of corrosion. Clean if necessary.
Test the battery voltage with a multimeter; it should be around 12.6 volts or higher when fully charged.

4. Perform Software Update

Access the vehicle’s settings menu on the touchscreen.
Navigate to the software section and check for any available updates.
Follow the prompts to download and install updates if available.

5. Tire Pressure Check

Use a tire pressure gauge to measure each tire's pressure.
Inflate or deflate to the recommended PSI as indicated on the driver’s door jamb.

6. Wiring Inspection

Inspect the dashboard wiring harness for any visible damage or loose connections.
Reconnect any loose plugs and secure all connections properly.
