Solution

1. Preparation

Gather Tools and Materials: OBD-II scanner, socket set, torque wrench, multimeter, shop towels, and safety gloves.
Safety Precautions: Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery before starting any repairs.

2. Address Engine Oil and Coolant Issues

Check Fluid Levels:
- Remove the engine oil dipstick and wipe it clean.
- Insert it back and remove to check the oil level.
- If low, add the correct type of engine oil as specified in the owner’s manual.
- Repeat the process for coolant in the reservoir; if low, add the manufacturer's recommended coolant.

3. Inspect and Repair Brake System

Remove Wheel:
- Use a lug wrench to loosen the lug nuts and lift the vehicle with a jack.
- Remove the wheel to access the brake assembly.
Inspect Brake Components:
- Check the brake pads for wear; replace if they are less than 3mm thick.
- Inspect the brake caliper for any signs of overheating or damage. Replace if necessary.
Reassemble:
- Reinstall the wheel, tighten lug nuts in a crisscross pattern to the manufacturer's torque specification.

4. Fix Electrical Short Circuits

Inspect Wiring:
- Use a multimeter to check for continuity in wiring harnesses, focusing on areas near the engine and battery.
- Replace any frayed or damaged wires.

5. Clear Codes and Test Drive

Clear Error Codes:
- Use the OBD-II scanner to clear any stored codes.
Test Drive the Vehicle:
- Monitor for any reoccurrence of the burning smell and verify that no new codes appear.
