Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, safety glasses, gloves.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the vehicle from the charging station if applicable.

2. Inspect Brake Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake components.
3. Inspect the brake pads for wear; replace if thickness is below manufacturer specifications (usually around 3mm).
4. Check the brake rotors for glazing or overheating signs; replace if necessary.
5. Reassemble the wheel and lower the vehicle.

3. Inspect Electrical Systems

Sub-steps:
1. Disconnect the negative terminal of the battery to ensure safety.
2. Visually inspect wiring harnesses for any signs of wear or damage.
3. Use a multimeter to check for continuity in electrical wires and connectors.
4. Repair or replace any damaged wiring or connectors found.

4. Battery Cooling System Check

Sub-steps:
1. Remove the cover of the battery compartment as per manufacturer’s guidelines.
2. Inspect the cooling fans for debris or blockage; clean if necessary.
3. Check the coolant level in the battery cooling system; top off with the recommended coolant if low.
