Solution

1. Preparation

Tools Required: Socket set, screwdrivers, OBD-II scanner, multimeter.
Ensure the engine is cool and the vehicle is parked on a flat surface.
Disconnect the battery to avoid any electrical hazards.

2. Inspect and Address Oil Leaks

Sub-steps:
1. Visually inspect the engine for oil leaks around the valve cover, oil pan, and gaskets.
2. Clean any oil spills with degreaser to identify new leaks.
3. Replace any faulty gaskets or seals as necessary; torque to manufacturer specifications (consult manual for specific values).

3. Check and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brakes.
2. Inspect brake pads and rotors for wear; replace if pads are below minimum thickness or if rotors show signs of overheating.
3. Ensure brake calipers are functioning properly, lubricate sliding pins, and reassemble.
4. Reinstall the wheel and torque to manufacturer specifications.

4. Inspect Wiring and Electrical Components

Sub-steps:
1. Visually inspect all wiring for signs of melting or damage, particularly in areas close to the exhaust.
2. Use a multimeter to test for shorts in the affected circuits.
3. Replace any damaged wiring or connectors; ensure connections are secure and insulated.

5. Check and Top-Up Fluid Levels

Sub-steps:
1. Inspect coolant reservoir and engine oil levels; top up as necessary.
2. If coolant is low, check for leaks in hoses, the radiator, and the water pump.
3. If any fluid appears burnt, consider a complete fluid replacement.
