Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe location with enough space to work.
Disconnect the negative terminal of the 12V battery to prevent electrical shock.

2. Battery Inspection and Testing

Sub-step 1: Reconnect the negative terminal of the 12V battery.
Sub-step 2: Test the battery voltage again; if it’s below 12.4 volts, proceed to replace the battery.
Sub-step 3: If voltage is acceptable, visually inspect the battery terminals for corrosion. Clean if necessary using a battery cleaning solution.

3. Jump-Start Procedure

Sub-step 1: Position a functioning vehicle close enough to use jumper cables safely.
Sub-step 2: Connect the red jumper cable to the positive terminal of the dead battery, then to the positive terminal of the functioning vehicle.
Sub-step 3: Connect the black jumper cable to the negative terminal of the functioning vehicle, then attach the other end to a non-painted metal surface on the dead vehicle.
Sub-step 4: Start the functioning vehicle and allow it to charge the dead battery for a few minutes before attempting to start the Tesla.

4. Key Fob Verification

Sub-step 1: If the vehicle still does not start, verify the key fob's battery by opening it.
Sub-step 2: Replace the key fob battery if it is low or dead, ensuring correct polarity during installation.

5. Final Checks

Sub-step 1: Reconnect any disconnected battery terminals securely.
Sub-step 2: Attempt to start the vehicle again. If problems persist, consult Tesla service for further diagnostics.
