Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, brake cleaner, multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety when working on electrical components.

2. Address Engine Component Issues

Inspect and Replace Worn Components:
- If leaks are found, replace gaskets or seals as needed.
- If electrical wires are damaged, repair or replace them.
- Torque specifications for gaskets should follow manufacturer guidelines.

3. Brake System Inspection and Repair

Remove Wheel and Inspect Brakes:
- Raise the vehicle and remove the wheel(s).
- Inspect brake pads for thickness; replace if less than 3mm or if they show signs of burning.
- Check rotors for warping or discoloration; machine or replace if necessary.
Reassemble:
- Reinstall the wheel and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs depending on the model).

4. Electrical System Inspection

Test and Replace Faulty Components:
- Use a multimeter to test the battery voltage; replace if below 12.4 volts.
- Check the alternator output while the engine is running; it should be between 13.8 to 14.4 volts. Replace if outside this range.
