Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, fuse puller, and basic hand tools (screwdriver set, socket set).
Ensure the vehicle is parked on a level surface, and the ignition is turned off.

2. Check and Replace Fuses

Locate the fuse box; refer to the owner’s manual for the specific fuse related to dashboard lights.
Use a fuse puller to remove the fuse in question.
Inspect the fuse for continuity using a multimeter. If blown, replace it with a fuse of the same amperage (typically 5A or 10A).

3. Inspect and Adjust the Dimmer Switch

Locate the dimmer switch on the dashboard, usually found near the headlight switch.
Rotate the dimmer switch to the maximum brightness position and observe if the dashboard lights illuminate.
If the dimmer switch is faulty, it may need replacement.

4. Check Wiring and Connectors

Remove the instrument cluster by unscrewing it from the dashboard (ensure to refer to specific steps in the service manual).
Inspect the wiring harness and connectors for any signs of wear, corrosion, or disconnection.
Clean any corroded connections with electrical cleaner and reattach securely.

5. Reassemble and Test

Reinstall the instrument cluster and ensure all screws are tightened to manufacturer specifications (typically around 5-7 Nm).
Reconnect the battery if previously disconnected.
Turn on the ignition to test the functionality of the dashboard lights before final assembly.
