Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, multimeter, brake pad gauge.
Ensure the vehicle is parked on a level surface and the engine is cool before beginning repairs.

2. Address Engine Oil Issues

Sub-steps:
1. Remove the oil dipstick and check oil level; add oil if low.
2. If oil appears burnt (dark and thick), drain and replace with new oil and filter.
3. Dispose of old oil following environmental regulations.

3. Repair or Replace Brake Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect brake pads for wear; replace if they are worn below the minimum thickness (typically 3mm).
4. Check rotors for warping or discoloration; replace if necessary.
5. Reassemble the wheel and lower the vehicle.

4. Inspect and Repair Electrical System

Sub-steps:
1. Examine all visible wiring and connectors under the hood for signs of damage.
2. Repair or replace any damaged wiring using appropriate gauge wire and connectors.
3. Use a multimeter to check for continuity in electrical circuits, ensuring proper connections.

5. Final Inspection

Double-check all fluid levels, connections, and components to ensure everything is secure and in proper working order.
