Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, fuse tester.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery before working on electrical systems.

2. Read and Clear Error Codes

Connect the OBD-II scanner to the diagnostic port under the dashboard.
Turn the ignition to the "ON" position without starting the engine.
Read and record any error codes that appear on the scanner.
Clear the error codes and observe if they return after a short drive.

3. Inspect and Replace Fuses

Locate the fuse box (check the owner’s manual for the exact location).
Use a fuse tester to check each fuse related to the dashboard warnings.
Replace any blown fuses with new ones of the same amperage.

4. Check and Top Up Fluid Levels

Open the hood and check the engine oil, coolant, and brake fluid levels.
Add fluids as necessary to reach the correct levels as specified in the owner’s manual.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness and connectors for any signs of damage, corrosion, or loose connections.
Repair or replace any damaged components as needed.

6. Test Brake System

Check the brake fluid reservoir for adequate fluid.
Inspect brake pads for wear and replace if necessary.
Test the brake system functionality (press the brake pedal to ensure it feels firm).
