Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, brake fluid tester, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery before starting any electrical work.

2. Inspect and Replace Brake Components

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Check brake pads for wear; replace if they are below the manufacturer's specifications.
Inspect the brake rotors for warping or scoring; replace if necessary.
Reassemble the brake components and wheel, ensuring all bolts are tightened to manufacturer specifications.

3. Electrical Inspection

Remove any covers or panels to access the wiring harnesses and connectors.
Visually inspect all wiring for signs of melting or damage.
Use a multimeter to test the connections for proper voltage and continuity.
Repair or replace any damaged wiring or connectors as needed.

4. Brake Fluid Check

Locate the brake fluid reservoir and check the fluid level.
Use a brake fluid tester to ensure fluid is not contaminated.
If necessary, bleed the brake lines to remove any air and refill with new brake fluid that meets manufacturer specifications.

5. Final Assembly

Reconnect the battery and ensure all components are securely fastened.
Perform a final inspection of all areas worked on.
