Solution

1. Preparation

Tools Required: Safety gloves, safety glasses, jack and jack stands, socket set, OBD-II scanner.
Park the vehicle on a level surface and ensure it is turned off. Allow the vehicle to cool before beginning any inspection.

2. Brake Inspection

Sub-steps:
1. Lift the vehicle using the jack and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect the brake pads for excessive wear; replace if they are worn down to the backing plate.
4. Check the brake rotors for signs of overheating, such as discoloration or warping.
5. Reassemble the wheel and lower the vehicle.

3. Fluid Leak Inspection

Sub-steps:
1. Check under the vehicle for any pooling fluids.
2. Inspect the engine bay for signs of fluid leaks from hoses or seals.
3. If any fluids are found, identify the source and replace the faulty component (e.g., hoses, seals).

4. Electrical System Check

Sub-steps:
1. Connect the OBD-II scanner to the vehicle’s port.
2. Review any fault codes related to the battery, motor, or electrical system.
3. If codes indicate issues, further inspect the affected components, such as the battery management system or wiring harness.

5. Cooling and Ventilation

Sub-steps:
1. Ensure the cooling system is functioning correctly; check coolant levels.
2. Inspect the radiator and cooling fans for debris or blockages.
3. Clean or replace any obstructed components to improve airflow.
