Solution

1. Preparation

Ensure the vehicle is parked on a level surface with the engine off and cooled down.
Gather tools and safety equipment.

2. Inspect and Address Fluid Leaks

Tools Required: Rags, flashlight
- Check for engine oil or coolant leaks; clean any spills.
- If leaks are found, replace the affected gaskets or seals and top off fluids.

3. Check and Replace Transmission Fluid

Tools Required: Socket set, transmission fluid
- Locate the transmission dipstick and remove it.
- Check fluid level and condition (should be red and not burnt).
- If necessary, drain and replace the transmission fluid according to manufacturer specifications.

4. Brake Inspection and Replacement (if applicable)

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner
- Remove the wheel and inspect brake pads, rotors, and calipers.
- If pads are worn down or overheating, replace brake pads and clean rotors.
- Ensure calipers are functioning properly and not sticking.

5. Electrical Inspection

Tools Required: Multimeter, wiring diagram (if available)
- Inspect wiring harness for insulation damage.
- Use a multimeter to check for shorts or faulty components.
- Repair or replace any damaged wiring or components as needed.

6. Final Assembly

Reassemble any components that were removed during inspection.
Tighten all bolts to manufacturer specifications and ensure nothing is left loose.
