Solution

1. Preparation

Park the vehicle on a level surface.
Ensure the engine is cool and the vehicle is in "Park."
Gather tools: OBD-II scanner, multimeter, basic hand tools.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if less than 3 mm of material remains.
3. Check the brake rotor for warping or overheating; replace if necessary.
4. Reassemble the wheel and torque lug nuts to the manufacturer's specification.

3. Check Electrical Systems

Sub-steps:
1. Visually inspect all wiring and connections for signs of damage or burning.
2. Use a multimeter to check for continuity in suspect wires.
3. Repair or replace damaged wiring as needed.
4. Clear any fault codes using the OBD-II scanner and test drive the vehicle.

4. Test Battery and Electrical Components

Sub-steps:
1. Measure the battery voltage with a multimeter; should be around 12.6 volts when not running.
2. Start the vehicle and check voltage; it should rise to around 14 volts.
3. If voltage is low, consider replacing the battery.
