Solution
1. Preparation
  • Park the vehicle on a level surface and engage the parking brake.
  • Gather necessary tools and ensure you have access to a suitable OBD-II scanner.
  • Ensure the vehicle is powered off before beginning work.
2. Update Software
  • Using the touchscreen, navigate to 'Software' and check for updates.
  • If an update is available, connect to Wi-Fi and download the update.
  • Follow the prompts to complete the installation process.
3. Inspect and Test the Drive Unit
  • If no software issues are identified, visually inspect the drive unit for any signs of damage or leaks.
  • Test the drive unit's performance using the Tesla diagnostics tool.
    • If abnormal noises or vibrations are detected, further disassembly may be needed.
4. Battery and Electrical System Check
  • Use a multimeter to check the voltage of the high-voltage battery pack.
  • Ensure all connections are secure and free from corrosion.
  • If the battery voltage is low, consider charging or replacing the battery.
5. Adjust Regenerative Braking Settings
  • From the touchscreen, navigate to ‘Driving’ settings.
  • Adjust the regenerative braking setting to see if this alleviates the jerking sensation during acceleration.
