Solution

1. Preparation

Ensure the vehicle is parked on a flat surface, and the ignition is turned off.
Gather necessary tools and parts for inspection.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt that may obstruct the sensors.
Check the wiring for any visible damage or disconnections.
Clean the sensor connectors with electrical contact cleaner.

3. Tire and Alignment Check

Inspect all tires for proper tread depth and wear; replace tires if necessary.
Verify that all tires are inflated to the manufacturer’s recommended pressure.
Check the wheel alignment with a professional alignment tool; adjust as needed.

4. Software Update

Connect the vehicle to Wi-Fi, and check for any available software updates through the Tesla interface.
If updates are available, install them to ensure the traction control system is operating with the latest software.

5. Test Traction Control

Conduct a test drive to monitor the traction control system’s functionality.
Accelerate gently from a stop to check if the traction control light remains off and the system engages appropriately.
