Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a flashlight.
Ensure the vehicle is parked, turned off, and the keys are removed.
Disconnect the battery to prevent electrical shock while working on the vehicle.

2. Inspect and Replace Fuses

Locate the fuse box, which is usually found under the dashboard or in the engine compartment.
Use a fuse puller or pliers to remove each fuse related to the dashboard gauges.
Inspect each fuse for continuity. If any are blown, replace them with fuses of the same amperage.
Reconnect the battery and test the dashboard gauges to see if functionality has returned.

3. Check and Secure Connections

Remove the dashboard panel to access the gauge cluster.
Inspect the wiring harness connected to the gauge cluster for any signs of damage or corrosion.
If loose, secure the connectors firmly and ensure there are no exposed wires.
Reassemble the dashboard panel and reconnect the battery.

4. Software Reset

If the gauges remain non-functional, perform a vehicle reset by turning the ignition to the "on" position without starting the engine.
Wait for several minutes and then turn off the ignition.
Restart the vehicle to see if the gauges have reset and are now operational.
