Solution
1. Preparation
  • Ensure the vehicle is parked safely on a level surface.
  • Disconnect the vehicle from any charging sources.
2. Battery Inspection
  • Check the battery state:
    • Access the battery status via the touchscreen.
    • If the battery is low, charge the vehicle until it reaches a sufficient level (at least 20%).
3. Gear Selector Inspection
  • Inspect the gear selector:
    • Remove any debris or obstructions around the gear selector area.
    • If the selector feels loose or unresponsive, consider inspecting the internal mechanism for wear or damage.
4. Brake Sensor Check
  • Check the brake pedal sensor:
    • Locate the brake sensor switch under the dashboard.
    • Inspect for proper connection and functionality.
    • If faulty, replace the brake pedal sensor.
5. Electrical System Check
  • Inspect the vehicle's electrical system:
    • Use a multimeter to check for any blown fuses related to the transmission control module.
    • Replace any blown fuses as needed, following the vehicle’s fuse box diagram.
6. Reset Vehicle Systems
  • Perform a soft reset of vehicle systems:
    • Hold down the brake pedal and press the scroll wheel buttons on the steering wheel until the screen goes black and restarts.
