Solution

1. Preparation

Gather necessary tools (OBD-II scanner, multimeter, socket set).
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the vehicle battery to prevent electrical shock while inspecting wiring.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Record any error codes displayed and refer to the repair manual for details.

3. Inspect Fuses

Locate the fuse box (refer to the owner's manual for location).
Use a fuse puller to remove and inspect each fuse related to the dashboard and warning lights.
Replace any blown fuses with new ones of the same amperage.

4. Check Battery and Connections

Use a multimeter to measure battery voltage; it should read around 12.6 volts when off.
Inspect battery terminals for corrosion or loose connections and tighten as necessary.
Clean any corrosion with a wire brush and apply dielectric grease.

5. Fluid Level Check

Open the hood and visually check the oil, coolant, and brake fluid levels.
Top off any low fluids using the appropriate type specified in the owner's manual.

6. Inspect Dashboard Wiring

Carefully remove the dashboard panel if necessary to access wiring.
Check for any loose, damaged, or corroded wires and repair or replace as needed.
Reassemble the dashboard panel securely after inspection.
