Solution

1. Preparation

Ensure the vehicle is in a safe location and parked on level ground.
Disconnect the battery to prevent any electrical hazards.
Gather all necessary tools and parts.

2. Inspect and Clean Electrical Connections

Remove covers from the battery and electrical components.
Check for corrosion or damage on battery terminals and wiring harnesses.
Clean any corrosion with a wire brush or contact cleaner.
Reconnect all connections securely.

3. Check and Replace Fluids

Inspect coolant levels in the reservoir; top off with manufacturer-recommended coolant if low.
If any fluids appear to be leaking, identify the source and replace the affected seals or gaskets as necessary.

4. Brake System Inspection

Remove the wheels to access the brake components.
Inspect brake pads for wear and replace if they are worn down.
Check brake calipers for sticking or overheating; replace if necessary.

5. Reassemble and Test

Reinstall wheels and securely torque all lug nuts to manufacturer specifications.
Reconnect the battery.
Start the vehicle and monitor for any unusual smells or warning lights.
