Solution

1. Preparation

Gather tools and parts required for repairs.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Scan and Clear Codes

Use the OBD-II scanner to connect to the vehicle's data link connector (DLC).
Retrieve and document the error codes.
Clear the codes and check if any reappear after a test drive.

3. Battery Inspection

Using the multimeter, test the battery voltage; if below 12.4 volts, replace the battery.
Check battery terminals for corrosion and clean if necessary.

4. Fuse Inspection and Replacement

Locate the fuse box under the dashboard or hood.
Identify and inspect fuses related to the dashboard lights; replace any blown fuses with the correct amperage.

5. Wiring Inspection

Visually inspect the wiring harness connected to the dashboard and other affected systems.
Repair or replace any damaged wires or connectors.

6. Reconnect Battery

Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay before starting the vehicle.
