Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, flashlight.
Ensure the vehicle is parked on a flat surface, turn off the engine, and allow it to cool down.

2. Identify and Fix Leaks

Locate leaking components: Look for oil leaks around the oil pan, valve covers, or gaskets.
Replace faulty seals or gaskets: Use the socket set to remove and replace any worn-out seals or gaskets.
Refill fluids: Top off any fluids that were low due to leaks.

3. Brake Inspection and Repair

Remove the wheel: Use a jack and jack stands to lift the vehicle safely.
Inspect brake components: Check pads, calipers, and rotors for signs of wear or overheating.
Replace worn brake pads: If needed, remove the caliper bolts and replace the brake pads with new ones, ensuring they are properly seated.
Reinstall the wheel: Torque the wheel lug nuts to the manufacturer's specifications.

4. Exhaust System Inspection

Check for damage: Inspect the exhaust manifold, catalytic converter, and pipes for cracks or holes.
Tighten loose connections: Use a socket set to secure any loose bolts on the exhaust system.
Replace damaged parts: If any components are damaged, replace them with OEM parts.
