Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the gear is in "Park."
Gather tools: multimeter, socket set, and a cleaning brush for terminals.
Disconnect the vehicle from any charging source.

2. Battery Inspection

Sub-step 1: Open the front trunk (frunk) and locate the 12V battery.
Sub-step 2: Use a multimeter to measure the voltage. If below 12.4 volts, replace the battery.
Sub-step 3: Remove the negative terminal (black) first, then the positive terminal (red) using a socket set.
Sub-step 4: Clean terminals with a brush to remove corrosion, if present.
Sub-step 5: Reattach the terminals, connecting the positive first, then the negative.

3. Starter Relay Check

Sub-step 1: Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
Sub-step 2: Remove the relay and test it with a multimeter for continuity.
Sub-step 3: If faulty, replace the relay with a new one.

4. Wiring Inspection

Sub-step 1: Inspect the wiring harness connected to the battery and starter for any visible damage.
Sub-step 2: Repair or replace any damaged wires as necessary to ensure a good connection.

5. Final Steps

Sub-step 1: Recheck all connections to ensure they are secure.
Sub-step 2: Attempt to start the vehicle again to confirm the issue is resolved.
