Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fluid catch pan.
Ensure the vehicle is parked on a flat surface and the engine is off. Allow the engine to cool before beginning work to avoid burns.

2. Address Fluid Leaks

Sub-steps:
1. Identify the source of any leaks found during the visual inspection.
2. Clean the affected area with a degreaser to remove any excess oil or fluid.
3. Replace any damaged hoses or seals that are leaking fluid.

3. Check and Replace Fluids

Sub-steps:
1. If fluid levels are low, top off engine oil, transmission fluid, and coolant with the manufacturer-recommended fluids.
2. If the fluid is discolored or burnt, drain and replace it, ensuring to follow the proper service procedure for each fluid type.

4. Electrical Repairs

Sub-steps:
1. Inspect all wiring and connectors for signs of damage or melting.
2. Replace any damaged wires or connectors as necessary.
3. Use electrical tape or heat shrink tubing to insulate repaired wires.

5. Brake Inspection and Repair

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads and rotors for excessive wear or damage.
3. Replace worn brake pads and ensure calipers are functioning correctly.
