Solution

1. Preparation

Tools Required: Safety glasses, gloves, OBD-II scanner, flashlight, basic hand tools (wrenches, sockets).
Ensure the vehicle is parked on a flat surface and the engine is off.
Allow the engine to cool down before starting any inspection.

2. Inspect for Fluid Leaks

Carefully examine the engine compartment, focusing on fluid reservoirs (engine oil, coolant, transmission fluid).
Use a flashlight to check for any signs of leaks or burnt fluid residue.
Clean up any leaks found and top off fluids as necessary.

3. Check Engine Oil

Remove the dipstick and check the oil level; add oil if low.
Inspect the oil for a burnt smell or dark color, indicating overheating.
If the oil is burnt, perform an oil change and replace the oil filter.

4. Inspect and Test Brake System

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to inspect the brake calipers and pads for wear or sticking.
Ensure that the caliper slides freely and replace any worn components.

5. Examine Electrical Connections

Visually inspect the wiring harness for any frayed wires or burnt connectors.
Use a multimeter to check for continuity in suspect wires.
Repair or replace any damaged wiring or connectors.

6. Replace Worn Belts and Hoses

Inspect belts for cracks, fraying, or excessive wear.
Replace belts with new ones if any damage is found.
Check hoses for leaks or brittleness and replace them if necessary.
