Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, multimeter, safety gloves, and goggles.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shock.

2. Inspect and Repair Electrical Components

Inspect wiring harnesses for damage or burnt sections.
- If damage is found, replace the affected wiring sections using appropriate gauge wire.
Check connections at the battery and main electrical distribution points for corrosion.
- Clean terminals with a wire brush and apply dielectric grease to prevent future corrosion.

3. Brake System Inspection

Remove the wheels to access the brake components.
- Use a jack to lift the vehicle and secure it with jack stands.
Inspect brake pads for excessive wear or burning.
- Replace if pads are below manufacturer specifications (typically 3 mm).
Check brake rotors for signs of overheating (blue discoloration).
- Resurface or replace rotors if necessary.

4. Coolant System Check

Inspect the radiator and hoses for leaks or damage.
Ensure the coolant level is adequate; refill with the manufacturer-recommended coolant type if low.
Pressure test the cooling system to identify any hidden leaks.

5. Final Assembly and Testing

Reinstall any components removed for inspection and repair.
Reconnect the battery and start the vehicle.
Monitor for any unusual smells or warning lights during a short test drive.
