Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools and equipment: OBD-II scanner, multimeter, basic hand tools, and a torque wrench.

2. Address Fault Codes

Use the OBD-II scanner to read the fault codes.
Identify the specific codes and their meanings; refer to a service manual if necessary.
Clear any temporary codes and check if they reappear after a short drive.

3. Inspect and Address Fluid Levels

Check engine oil level and condition using the dipstick; top off with the manufacturer-recommended oil if low.
Inspect coolant level in the reservoir; add coolant if needed, ensuring it is the correct type.
Check transmission fluid level according to the manufacturer’s specifications; add fluid if necessary.

4. Inspect Battery and Electrical System

Use a multimeter to test the battery voltage; replace if below 12.4 volts.
Inspect battery terminals for corrosion; clean and tighten if necessary.

5. Brake System Inspection

Check the brake fluid reservoir; top off if fluid is low and inspect for leaks.
Look for wear on brake pads and rotors; replace if necessary.

6. Tire Inspection

Verify the tire pressures using a tire pressure gauge; inflate to the recommended PSI.
Inspect tires for visible damage or uneven wear; replace if necessary.
