Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, and flashlight.
  • Ensure the vehicle is turned off and parked on a level surface.
  • Disconnect the vehicle from any charging source.
2. Inspect Battery Connections
  • Sub-step 1: Open the front trunk (frunk) and locate the 12V battery.
  • Sub-step 2: Check all battery terminals for tightness; tighten if necessary.
  • Sub-step 3: Clean any corrosion using a wire brush and a mixture of baking soda and water, then rinse with clean water and dry.
3. Test Battery Voltage
  • Sub-step 1: Set the multimeter to measure DC voltage.
  • Sub-step 2: Connect the multimeter probes to the 12V battery terminals (positive to positive, negative to negative).
  • Sub-step 3: Check if the voltage reads between 12.4V to 12.6V for a healthy battery; if below, consider replacing the battery.
4. Inspect Fuses
  • Sub-step 1: Locate the fuse box, usually near the front of the vehicle under the dash or frunk.
  • Sub-step 2: Remove the cover and visually inspect all fuses for any that appear blown.
  • Sub-step 3: Replace any blown fuses with the same amperage rating.
5. Check Wiring and Connectors
  • Sub-step 1: Inspect the wiring harness connected to the dashboard and battery for any visible damage or fraying.
  • Sub-step 2: Ensure all connectors are seated properly and free of corrosion.
  • Sub-step 3: Repair or replace damaged wiring and connectors as necessary.
