Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, brake cleaner.
Ensure vehicle is parked on a level surface and the engine is off and cool.

2. Address Fluid Leaks

Identify Leak Source
- Clean the area around the suspected leak with brake cleaner.
- Start the engine and observe for any new leaks.
Replace Damaged Components
- If oil or coolant is leaking, replace the faulty gasket, seal, or hose.
- Use manufacturer-recommended fluids for refills.

3. Inspect and Replace Brake Components

Remove Wheel
- Loosen lug nuts and lift the vehicle using a jack.
- Remove the wheel to access brake components.
Inspect Brake Pads and Rotors
- Check brake pads for thickness; replace if below the manufacturer's minimum specification.
- Inspect rotors for scoring or warping; replace if necessary.
Reassemble and Torque
- Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.

4. Check Electrical Systems

Inspect Wiring
- Look for damaged or frayed wires near the engine and undercarriage.
- Repair or replace any damaged wiring.
Test Electrical Components
- Use a multimeter to check for proper voltage in critical circuits.
- Replace any failing components (e.g., sensors, connectors).
