Solution

1. Preparation

Gather tools and equipment needed for the repair.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the 12V battery to prevent electrical shock during inspection.

2. Update Software

Power on the vehicle and navigate to the settings menu on the touchscreen.
Select “Software” and check for updates.
If an update is available, follow the prompts to install the latest software version.

3. Inspect Throttle Pedal Assembly

Remove the floor mat and any covers obstructing access to the throttle pedal.
Visually inspect the throttle pedal for any signs of wear or obstruction.
Ensure the throttle pedal moves freely without resistance. If it's stuck, clean the area or replace the assembly if damaged.

4. Test Battery Connections

Reconnect the 12V battery and ensure all terminals are clean and tight.
Test the high-voltage battery's voltage with a multimeter; it should be within the manufacturer's specified range.
If the voltage is low, consider charging the battery or having it checked at a service center.

5. Recheck for Error Codes

After performing the above steps, reconnect the OBD-II scanner.
Check for any new error codes and document them for further analysis.
If codes related to the drive system appear, refer to the manufacturer’s repair guidelines.
