Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document all error codes.
Research each code to determine the underlying issue and follow appropriate repair procedures based on the specific faults.

3. Check Fluid Levels

Open the hood and check all essential fluids using dipsticks or sight glasses.
- Engine oil: Top off or change if low or dirty.
- Brake fluid: Ensure it is at the recommended level; fill with the correct type if needed.
- Coolant: Check the reservoir and refill if necessary with the appropriate coolant mixture.

4. Tire Pressure Check

Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires to match the manufacturer's recommended pressure (usually found on a label inside the driver’s door).

5. Brake System Inspection

Inspect brake fluid lines and calipers for leaks.
Check the condition of brake pads and rotors; replace if worn beyond specifications.
If necessary, bleed the brake system to remove any air.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any stored codes after repairs are made.
Ensure that the warning lights have turned off.
