Solution

1. Preparation

Tools Required: Jack stands, socket set, multimeter, OBD-II scanner, basic hand tools.
Safely park the vehicle on a level surface and engage the parking brake. Allow the engine to cool before proceeding.

2. Address Fluid Leaks

Sub-steps:
1. Locate any visible fluid leaks under the vehicle.
2. If oil is leaking, replace any damaged oil gaskets or seals.
3. For coolant leaks, inspect hoses and the radiator for cracks and replace as necessary.

3. Brake System Inspection

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for thickness; replace if worn down to 3mm or less.
3. Check rotors for heat spots; replace if warped or excessively worn.
4. Clean brake calipers and ensure proper function.

4. Electrical System Repair

Sub-steps:
1. Use a multimeter to test the battery voltage; replace if below 12.4 volts.
2. Inspect all wiring connections for fraying or melting; repair or replace damaged wires.
3. Replace any burnt fuses found during inspection.

5. Engine Component Replacement

Sub-steps:
1. If any engine components are identified as burnt, such as wiring harnesses or sensors, remove and replace them.
2. Ensure all connections are secure and free of corrosion after replacement.
