Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Retrieve Diagnostic Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner instructions to read and record error codes.

3. Address Fluid Levels

Check oil level using the dipstick; add oil if low (use recommended oil type).
Inspect coolant level in the reservoir; top up with the appropriate coolant.
Verify brake fluid level; add fluid if necessary.

4. Inspect the Battery

Use a multimeter to check the battery voltage; it should be around 12.6 volts or higher.
Clean battery terminals and cables if corrosion is present.
Replace the battery if voltage is low or it fails to hold a charge.

5. Brake System Inspection

Visually check brake lines for leaks or damage.
Inspect brake pads and rotors for wear; replace if necessary.
Test the brake fluid for moisture content; replace if contaminated.

6. Verify Tire Pressure

Check the tire pressure using a tire gauge; inflate to the manufacturer’s specification.
Inspect for any visible tire damage or wear.
