Solution

1. Preparation

Gather Tools and Materials: OBD-II scanner, multimeter, socket set, torque wrench, brake cleaner, replacement brake pads (if necessary).
Safety Precautions: Disconnect the vehicle's battery to prevent electrical shorts while inspecting.

2. Addressing Overheating Brakes

Remove Wheel:
1. Loosen lug nuts with a socket set.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheel to access the brakes.
Inspect Brake Pads and Rotors:
1. Check brake pads for wear; replace if less than 3mm thickness.
2. Inspect rotors for scoring or overheating (blue discoloration).
Replace Brake Pads (if necessary):
1. Remove caliper bolts with a socket set.
2. Carefully lift the caliper off the rotor.
3. Remove and replace the brake pads.
4. Reassemble caliper and wheel; torque lug nuts to manufacturer specifications.

3. Check Electrical System

Inspect Wiring:
1. Look for damaged or burnt wires around the battery and charging system.
2. Replace any damaged connectors or wiring.
Test Battery Health:
1. Use a multimeter to check battery voltage; should read around 12.6 volts when fully charged.
2. If voltage is low, consider replacing the battery.

4. Fluid Leaks

Identify and Fix Leaks:
1. Clean any spilled fluids using brake cleaner.
2. Replace any leaking hoses or seals.
