my Tesla Model S Plaid/Refresh (2021-present) won't start just clicks what should I check?

Solution

1. Preparation

• Gather tools: multimeter, socket set, and cleaning supplies.
• Ensure the vehicle is in "Park" mode.
• Disconnect the vehicle from any charging source.

2. Inspect and Clean Battery Connections

• Open the front trunk to access the 12V battery.
• Using a socket set, carefully remove the negative terminal first, followed by the positive terminal.
• Inspect the terminals and cables for corrosion or damage.
• Clean the terminals with a wire brush and a solution of baking soda and water to neutralize corrosion.
• Reconnect the positive terminal first, followed by the negative terminal, ensuring they are securely tightened.

3. Replace the 12V Battery (if necessary)

• If the 12V battery voltage is below 12.4 volts after testing, it should be replaced.
• Remove the old battery by disconnecting terminal connections, unbolting, and lifting it out of the tray.
• Install the new battery by placing it in the tray, securing it with bolts, and reconnecting the terminals (positive first).

4. System Reset

• After reconnecting the battery, perform a system reset by pressing and holding the brake pedal and the start button until the vehicle's systems reboot.
• Allow the vehicle to power on completely before attempting to start.
