Solution

1. Preparation

Gather tools including a multimeter, socket set, and OBD-II scanner.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.
Disconnect the 12V battery to ensure safety while inspecting electrical components.

2. Inspect and Repair Electrical Components

Check Wiring:
- Inspect wiring harnesses in the front area for any signs of fraying or corrosion.
- Use a multimeter to test for continuity and ground issues.
Repair or Replace Damaged Wires:
- If damaged, cut out the affected section and splice in new wire using solder or appropriate connectors.
- Ensure all connections are insulated properly.

3. Inspect Brake System

Remove Front Wheels:
- Use a socket set to remove the lug nuts and take off the front wheels.
Inspect Brakes:
- Check brake pads and rotors for signs of excessive wear or overheating.
- Replace brake components if they show signs of damage or if pads are worn below the minimum thickness.
Reassemble:
- Reinstall the wheels and torque the lug nuts to the manufacturer's specifications.

4. Check Battery Cooling System

Inspect Cooling Ducts:
- Open the front trunk and remove any covers to access the battery cooling system.
- Ensure there are no obstructions in the cooling ducts.
Test Cooling Fans:
- Turn on the vehicle and monitor the operation of the cooling fans for proper functionality.
Replace Fans if Necessary:
- If fans do not operate, replace them with new units according to manufacturer specifications.
