Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, multimeter, safety gloves, safety goggles.
Ensure the vehicle is parked on a flat surface, and the engine is cool before beginning any inspection or repairs.

2. Addressing Fluid Leaks

Sub-steps:
1. Identify the source of any fluid leaks discovered during the visual inspection.
2. If oil is leaking, replace any damaged gaskets or seals.
3. Clean up any spilled fluids using appropriate absorbent materials.
4. Refill any low fluids to the manufacturer-specified levels.

3. Repairing Electrical Issues

Sub-steps:
1. Inspect damaged wiring and connectors found during the inspection.
2. Replace any frayed or burnt wires with new wiring of the same gauge.
3. Use heat shrink tubing or electrical tape to insulate repaired areas.
4. Ensure all connectors are securely mounted and free of corrosion.

4. Brake System Maintenance

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for wear; replace if thickness is below the manufacturer’s specification.
3. Check rotors for warping or overheating; replace if necessary.
4. Reassemble the brake components and wheel, ensuring proper torque specifications are met.
