Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is off and cool. Disconnect the battery before starting work on electrical components.

2. Inspect and Clean Engine Components

Sub-steps:
1. Remove the engine cover (if applicable) using the socket set.
2. Visually inspect the wiring harness for melted insulation or burnt wires.
3. Check for oil leaks around gaskets and seals; replace any damaged gaskets.
4. Clean any oil spills with an appropriate degreaser.

3. Brake Inspection and Repair

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake components.
3. Inspect brake pads for thickness; replace if they are less than 3mm.
4. Check rotors for signs of overheating (discoloration or scoring); replace if necessary.
5. Reassemble the wheel and lower the vehicle.

4. Electrical System Assessment

Sub-steps:
1. Use a multimeter to check the battery voltage; replace the battery if voltage is below 12.4V.
2. Inspect the alternator for proper operation and check for loose connections.
3. Replace any damaged fuses or wiring found during inspection.

5. Final Assembly and Testing

Reconnect the battery and ensure all tools are removed from the engine bay.
Start the engine and let it idle to check for burning smells.
Conduct a short test drive to ensure everything is functioning properly.
