Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, multimeter, flashlight.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Allow the engine to cool down before proceeding to avoid burns.

2. Inspect Electrical Components

Sub-steps:
1. Open the hood and visually inspect all wiring harnesses for burnt or frayed wires.
2. Use a multimeter to check for any short circuits in the wiring.
3. Disconnect any damaged wires and replace them with new wiring of the same gauge.

3. Examine Brake System

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for excessive wear or overheating signs.
3. If pads are worn, replace them with new ones according to manufacturer specifications.
4. Check the brake rotors for warping or damage; replace if necessary.

4. Inspect Fluid Levels

Sub-steps:
1. Check the engine oil level and condition; change oil if it appears burnt or low.
2. Inspect coolant levels and ensure there are no leaks in the cooling system.
3. If coolant is low, fill to the proper level and check for leaks after repairs.
