Solution

1. Preparation

Tools Required:
- Multimeter
- Wrench (for battery terminals)
- Torque wrench (if applicable)
Ensure the vehicle is parked safely and in a well-ventilated area.
Disconnect the main battery pack if necessary for safety.

2. Check 12V Battery

Inspect Battery Condition:
- Locate the 12V battery under the front trunk (frunk).
- Use a multimeter to confirm the voltage is above 12.4V. If it is below, proceed to the next step.
Charge or Replace 12V Battery:
- If the battery is low, connect a compatible battery charger to the terminals.
- If the battery does not hold a charge, prepare to replace it.
- Disconnect the negative terminal first, followed by the positive terminal.
- Remove the old battery and install the new one, connecting the positive terminal first.
- Tighten connections to manufacturer's specifications (usually around 10-12 ft-lbs).

3. Reset System

Perform a Soft Reset:
- With the vehicle in "Park," press and hold both scroll wheels on the steering wheel until the touchscreen resets.
- Wait for the reboot to complete and check if the vehicle starts.

4. Check High Voltage Battery

If the vehicle still does not start, check the high-voltage battery status through the Tesla app.
If the high-voltage battery is depleted, it may need to be charged using a Tesla Supercharger.
