Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, fluid catch pan.
Ensure the vehicle is parked on a level surface, and the engine is cool before starting work.

2. Fluid Inspection

Oil Check:
- Remove the dipstick, wipe it clean, reinsert it, then remove it again to check the oil level.
- If oil is low, add the manufacturer-recommended oil type.
- If oil appears burnt, drain the oil and replace it with fresh oil and a new oil filter.
Transmission Fluid Check:
- With the vehicle running, locate the transmission dipstick; remove and check fluid level.
- If the fluid is low or burnt, drain and replace with the appropriate transmission fluid.

3. Brake Inspection

Remove the wheel to access the brake components.
Inspect brake pads and rotors for wear; replace any that are excessively worn or damaged.
Check for caliper functionality; ensure it is not sticking and causing overheating.

4. Component Inspection

Examine belts and hoses for wear; replace any that are cracked or frayed to prevent further issues.
Look for any electrical components that may be overheating; repair or replace as necessary.
