Solution

1. Preparation

Gather tools: OBD-II scanner, tire pressure gauge, multimeter, basic hand tools.
Ensure the vehicle is in a safe and accessible location with sufficient lighting.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Scan for error codes and note any codes that appear.
Refer to a diagnostic trouble codes (DTC) guide to interpret the codes and determine the necessary repairs.

3. Inspect Fluid Levels

Open the hood and check engine oil level using the dipstick; add oil if low.
Inspect coolant reservoir and top up with the appropriate coolant mixture if necessary.
Check brake fluid level and refill with DOT-approved fluid if needed.
Inspect transmission fluid level and quality; add fluid if low.

4. Battery Inspection

Disconnect the negative terminal of the battery using a wrench.
Inspect battery terminals for corrosion; clean with a wire brush if necessary.
Reconnect the battery terminal securely and check voltage using a multimeter (should be 12.6V or higher).

5. Tire Pressure Check

Use a tire pressure gauge to check the pressure of each tire.
Inflate tires to the recommended PSI as indicated on the driver's side door jamb.
Inspect tires for any signs of wear, damage, or punctures.

6. Fuse Inspection

Locate the fuse box (usually under the dashboard or in the engine bay).
Refer to the fuse box diagram to find fuses related to dashboard and warning lights.
Remove any blown fuses and replace them with new fuses of the same amperage.
