Solution

1. Preparation

Tools Required: Tesla-compatible OBD-II scanner, tire pressure gauge, basic hand tools (screwdrivers, socket set)
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Adjustment

Sub-steps:
1. Using a tire pressure gauge, check the pressure of all four tires.
2. Inflate or deflate tires to the manufacturer's recommended pressure (usually found on the driver's door jamb).
3. Inspect tires for uneven wear or damage; replace if necessary.

3. Brake System Inspection

Sub-steps:
1. Remove the wheel to access the brake system (if necessary).
2. Inspect brake pads for wear; replace if thickness is below the manufacturer's specification.
3. Check brake sensors for proper connection and functionality.
4. Test the brake fluid level and condition; replace fluid if contaminated.

4. Software Update

Sub-steps:
1. Connect the vehicle to a Wi-Fi network.
2. Navigate to the “Software” section on the touchscreen.
3. Check for any available updates and install them as prompted.

5. ABS and Traction Control System Check

Sub-steps:
1. Inspect the ABS sensors at each wheel for damage or disconnection.
2. Clean any dirt or debris from the sensors.
3. If necessary, replace faulty ABS sensors that may be causing the traction control light to illuminate.
