Solution

1. Preparation

Ensure the vehicle is in a safe location with enough space to work.
Gather tools: multimeter, socket set, and any necessary cleaning supplies.
Disconnect the main battery for safety.

2. Inspect and Clean Battery Connections

Sub-step 1: Open the frunk (front trunk) and locate the 12V battery.
Sub-step 2: Using a socket set, carefully remove the negative terminal first, followed by the positive terminal.
Sub-step 3: Inspect the terminals for corrosion; clean with a mixture of baking soda and water if necessary.
Sub-step 4: Reconnect the positive terminal first, then the negative terminal, ensuring they are securely tightened.

3. Test or Replace the 12V Battery

Sub-step 1: Using a multimeter, check the voltage of the 12V battery. It should read around 12.6 volts when fully charged.
Sub-step 2: If the voltage is below 12.4 volts, charge the battery using a compatible battery charger.
Sub-step 3: If the battery cannot hold a charge or is significantly below the voltage threshold, replace the 12V battery with a new one.

4. Reset the Vehicle Systems

Sub-step 1: Reconnect the main battery if disconnected.
Sub-step 2: Power on the vehicle and perform a soft reset by holding down the steering wheel buttons until the screen resets.
Sub-step 3: Check for any error messages on the dashboard and clear them if possible.
