Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the vehicle from any charging source.

2. Battery Inspection

Step 1: Remove the frunk lid to access the 12V battery.
Step 2: Inspect the battery terminals.
- Use a wire brush to clean any corrosion.
- Tighten any loose connections using a socket set.
Step 3: Measure the battery voltage with a multimeter.
- If the voltage is below 12.4V, the battery may be discharged.

3. Jump-starting the Vehicle

Step 1: Use jumper cables to connect the 12V battery to a functioning vehicle.
- Connect the positive (red) cable to the positive terminal of the dead battery.
- Attach the other end to the positive terminal of the working battery.
- Connect the negative (black) cable to the negative terminal of the working battery.
- Attach the other end to a metal ground on the Model Y.
Step 2: Attempt to start the Model Y after a few minutes of connection.
Step 3: If successful, allow the vehicle to charge for at least 30 minutes before disconnecting.

4. Battery Replacement (if necessary)

Step 1: If the 12V battery is confirmed faulty, remove it carefully.
- Disconnect the negative terminal first, followed by the positive terminal.
- Remove any securing brackets and lift out the battery.
Step 2: Install the new 12V battery.
- Place it in the compartment and secure it with brackets.
- Connect the positive terminal first, then the negative terminal.
Step 3: Reinstall the frunk lid.
