Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Screwdrivers
Torque wrench

2. Inspect the Dimmer Switch

Locate the dimmer switch on the dashboard.
Rotate the dimmer switch to its maximum setting to ensure that it is not set too low.
If lights illuminate, the issue was a simple adjustment. If not, proceed to the next step.

3. Check Fuses

Open the fuse box cover, usually located under the dashboard or near the driver's side.
Identify the fuse related to the dashboard lights (refer to the fuse diagram).
Remove the fuse and inspect it; replace it if blown.
Reinstall the fuse and recheck if the dashboard lights work.

4. Scan for DTCs

Connect the OBD-II scanner to the vehicle's port.
Turn on the ignition without starting the engine.
Scan for any trouble codes and note them down.
Address any codes that specifically relate to electrical issues.

5. Inspect Wiring and Connectors

Remove the dashboard cover to access the wiring harness.
Visually inspect for frayed wires, corrosion, or loose connections.
If any issues are found, repair or replace the damaged wiring or connectors.

6. Test Voltage at Dashboard Circuit

Reconnect battery and turn on the ignition.
Set the multimeter to measure DC voltage.
Probe the dashboard light circuit connection to check for voltage.
If no voltage is present, trace back to the source for further testing.

7. Replace Dashboard Bulbs

If all previous steps are clear, remove the dashboard assembly.
Unscrew and replace any burnt-out bulbs with new ones.
Reassemble the dashboard and test the lights.
