Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and electrical cleaner.
Ensure the vehicle is parked on a level surface and turn off the ignition.

2. Update Software

Connect the vehicle to Wi-Fi.
Access the settings menu on the dashboard display.
Navigate to the software update section and follow prompts to install any available updates.

3. Inspect Battery and Connections

Use a multimeter to measure battery voltage; it should be approximately 12.6 volts when the vehicle is off.
Disconnect the battery terminals (negative first, then positive).
Clean the battery terminals with electrical cleaner and a wire brush.
Reconnect the terminals (positive first, then negative) and ensure they are tight.

4. Check Wiring and Grounding

Remove the dashboard cover to access wiring.
Inspect all connectors and wires for damage; repair or replace as necessary.
Check grounding points: remove, clean, and reattach to ensure a solid connection.

5. Test Components

Reconnect the battery and turn on the vehicle.
Monitor the dashboard for flickering. If flickering persists, consider replacing the dashboard display unit or further inspecting the internal components.
