Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, jack and jack stands.
Ensure the vehicle is on a flat surface and turn off the ignition.
Disconnect the battery to prevent any electrical shock.

2. Inspect and Secure Drivetrain Components

Sub-steps:
1. Use a jack to lift the vehicle and secure it with jack stands.
2. Visually inspect the drivetrain components (axles, differential, etc.) for any signs of damage or wear.
3. Tighten any loose bolts using a torque wrench to the manufacturer's specifications.

3. Electric Motor Inspection

Sub-steps:
1. Remove the cover of the electric motor to access internal components.
2. Check for any signs of wear or debris within the motor housing.
3. Use a multimeter to test the motor's electrical connections and ensure proper voltage levels.
4. Reassemble the motor cover after inspection.

4. Battery Connection Check

Sub-steps:
1. Inspect the battery terminals for corrosion or loose connections.
2. Clean any corrosion with a wire brush and reconnect the terminals securely.
3. Test the battery voltage using a multimeter to ensure it is within normal operating range.

5. Test Drive

Sub-steps:
1. Reconnect the battery and lower the vehicle from the jack stands.
2. Start the vehicle and take it for a test drive to see if the whining noise persists.
3. Monitor for any abnormal sounds or loss of power during acceleration.
