Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, fuse puller, basic socket set.
Ensure the vehicle is in park and turned off. Disconnect the 12V battery to prevent electrical shock.

2. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuses related to the dashboard and instrument cluster using the fuse diagram.
Use a fuse puller to remove the suspected blown fuses. Inspect them visually or use a multimeter to check continuity.
Replace any blown fuses with new ones of the same amperage.

3. Inspect and Test the 12V Battery

Using a multimeter, measure the voltage of the 12V battery. It should read around 12.6 volts when fully charged.
If the battery voltage is low, charge the battery or replace it if it's old or defective.
Ensure that the battery terminals are clean and securely connected.

4. Wiring Inspection

Reconnect the 12V battery.
Remove the dashboard cover to access the wiring harness and connectors.
Visually inspect all wiring for frays, corrosion, or loose connections.
If any wires are damaged, repair or replace them as needed.

5. Touchscreen Reset

Perform a soft reset by holding down the scroll wheels on the steering wheel until the touch screen restarts.
Observe if the dashboard lights up after the reset.
