Solution

1. Preparation

Tools Required: Socket set, torque wrench, OBD-II scanner, multimeter, flashlight
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while inspecting electrical components.

2. Inspect Suspension Components

Visually inspect the suspension components (control arms, bushings, and shocks) for signs of wear.
Sub-steps:
- Remove the wheel covers or hubcaps if necessary.
- Use a socket set to check the tightness of suspension bolts and nuts; torque to manufacturer specifications.
- Replace any worn bushings or components as needed.

3. Brake System Inspection

Tools Required: Brake caliper tool, torque wrench
Inspect the brake pads and rotors for wear, ensuring that they are within the manufacturer's specifications.
Sub-steps:
- Remove the wheel to access the brake system.
- Check the brake pads for thickness; replace if less than 3mm.
- Inspect the rotors for grooves or warping; replace if necessary.
- Reassemble and torque wheel lugs to specification.

4. Electrical System Check

Tools Required: Multimeter
Test the inverter and electric motor for proper function.
Sub-steps:
- Reconnect the battery and power on the vehicle.
- Use a multimeter to measure voltage output from the inverter.
- Listen for any abnormal sounds while testing motor functions.
