why is my Tesla Model 3 Highland (2024-present) dashboard light flickering

Solution

1. Preparation

• Tools Required: Multimeter, OBD-II scanner (compatible with Tesla), basic hand tools (screwdrivers, pliers).
• Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
• Disconnect the 12V battery negative terminal to prevent any electrical shorts during inspection.

2. Inspect and Test 12V Battery

• Sub-steps:
  1. Use a multimeter to measure the voltage of the 12V battery.
  2. If the voltage is below 12.4V, consider replacing the battery.
  3. Check battery connections for corrosion; clean if necessary.
  4. Reconnect the 12V battery after inspection.

3. Examine Electrical Connections

• Sub-steps:
  1. Remove any panels covering the dashboard area to access electrical connections.
  2. Inspect all connectors and wiring for any signs of damage or loose connections.
  3. Tighten any loose connections and replace any damaged wiring or connectors.
  4. Reassemble the panels securely.

4. Update Software

• Sub-steps:
  1. Reconnect the vehicle to Wi-Fi if it isn’t already.
  2. Go to the software update section of the Tesla interface and check for updates.
  3. Follow prompts to download and install any available updates.
  4. Allow the vehicle to reboot after the update is complete.

5. Perform a System Reset

• Sub-steps:
  1. With the vehicle in park, hold down both scroll wheels on the steering wheel until the screen goes black and then the Tesla logo appears.
  2. Wait for the system to reboot fully before testing the dashboard lights again.
