Solution

1. Preparation

Gather necessary tools and parts: OBD-II scanner, basic socket set, brake cleaner, rags, new brake pads/rotors if needed.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues during inspection.

2. Inspect and Clean Engine Bay

Step 1: Open the hood and visually inspect all hoses, wires, and connections for damage.
Step 2: Clean any spilled fluids using brake cleaner and rags.
Step 3: If oil is found, identify the source of the leak (valve cover gasket, oil filter, etc.).

3. Brake Inspection

Step 1: Remove the wheel to access the brake components.
Step 2: Inspect brake pads for wear; replace if they are less than 3mm thick.
Step 3: Check the brake rotors for warping or glazes; replace if necessary.
Step 4: Reassemble the brake components and wheel.

4. Transmission Fluid Check

Step 1: Locate the transmission dipstick and check fluid levels.
Step 2: If the fluid is dark or has a burnt smell, drain and replace the transmission fluid.
Step 3: Refill with manufacturer-recommended fluid type.
