Solution
1. Preparation
  • Tools Required: Multimeter, socket set, terminal cleaner, soft cloth.
  • Ensure the vehicle is parked in a safe, well-ventilated area.
  • Disconnect any accessories connected to the vehicle to avoid electrical interference.
2. Inspect and Test the 12V Battery
  1. Access the 12V Battery: Remove any covers or panels to access the 12V battery located in the front trunk (frunk).
  2. Check Voltage: Use a multimeter to measure the 12V battery voltage.
    • It should read between 12.4 to 12.6 volts for a fully charged state.
  3. Charge or Replace: If the voltage is below 12.4 volts:
    • Charge the battery using a compatible charger.
    • If unable to hold a charge, replace the battery with a new, OEM-compatible battery.
3. Check High-Voltage Battery Status
  1. Inspect for Warnings: Use the touchscreen to check for any messages regarding the high-voltage battery.
  2. Check Battery Health: If accessible, use diagnostic software to assess the high-voltage battery health.
4. Secure Connections
  1. Inspect Battery Connections: Check the positive and negative terminals of the 12V battery.
    • Clean any corrosion using a terminal cleaner and a soft cloth.
    • Ensure the terminals are tightly secured.
5. Reset Vehicle Systems
  1. Perform Soft Reset: Hold down both scroll wheels on the steering wheel until the Tesla logo appears on the screen.
    • This may resolve any software-related issues preventing the vehicle from starting.
