Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shocks.

2. Inspect Battery Connections

Remove the negative battery terminal using a socket wrench.
Clean any corrosion from the battery terminals and cable ends using a wire brush.
Tighten the battery terminals securely before reconnecting.

3. Check Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuses related to the dashboard and electronics as per the owner's manual.
Remove each fuse one at a time and visually inspect for continuity or use a multimeter.
Replace any blown fuses with the same amperage rating.

4. Inspect Wiring Harness

Carefully remove the dashboard cover if necessary to access the wiring harness.
Visually inspect the wiring for signs of wear, fraying, or damage.
Repair or replace any damaged wires as needed.

5. Test Dashboard Display Unit

Reconnect the battery and turn on the ignition.
Use a multimeter to check the voltage at the dashboard display connector.
If voltage is inconsistent or absent, further investigate the wiring leading to the display unit.
