Solution

1. Preparation

Gather Tools and Parts: OBD-II scanner, flashlight, multimeter, socket set, torque wrench, coolant, engine oil, brake pads (if needed).
Safety Warning: Disconnect the battery before working on electrical components.

2. Address Fluid Leaks

Inspect for Leaks: Clean the area and check for leaks of oil, coolant, or transmission fluid.
Top Off Fluids: If low, add the appropriate fluids (engine oil, coolant).
Replace Gaskets or Seals: If leaks are detected, replace any damaged gaskets or seals.

3. Replace Worn Components

Belts and Hoses: Inspect and replace any damaged or worn belts and hoses.
- Sub-steps:
  - Loosen the tensioner using a socket wrench.
  - Remove the old belt or hose and replace it with a new one.
  - Tighten the tensioner to manufacturer specifications.
Brake Pads: If brake pads are found to be burnt:
- Remove the wheel and caliper to access the brake pads.
- Replace with new brake pads and ensure they are properly seated.

4. Check and Repair Electrical System

Inspect Wiring: Look for frayed or damaged wiring that could cause a short circuit.
Test Battery Voltage: Use a multimeter to check battery voltage; replace if below 12.4 volts.
Repair or Replace Components: Any faulty electrical components identified must be repaired or replaced as necessary.
