Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, brake cleaner, and safety gear.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Address Engine Components

Step 1: Check for burnt wiring or components.
- Remove engine cover (if applicable) using the socket set.
- Visually inspect wiring harnesses and connectors.
Step 2: If any burnt components are found, replace them as necessary.
- Disconnect the battery before proceeding with any electrical repairs.

3. Brake System Inspection

Step 1: Remove the wheel to access the brake system.
- Use a jack to lift the vehicle and secure it with jack stands.
Step 2: Inspect the brake pads and rotors for excessive wear or glazing.
- If pads are worn down below the manufacturer’s specifications, replace them.
Step 3: Check the brake calipers for proper function.
- Ensure calipers are not stuck or causing excessive friction.

4. Fluid Leak Repair

Step 1: Identify the source of any fluid leaks.
- Clean the area where fluid is present and monitor for reoccurrence.
Step 2: Replace any leaking hoses or seals as needed.
- Ensure all replaced components are properly torqued to manufacturer specifications.

5. Final Checks

Reassemble any components removed during inspection.
Reconnect the battery and clear any error codes from the OBD-II scanner.
