Solution

1. Preparation

Tools Required: Tesla mobile app, diagnostic software (if applicable), tire pressure gauge.
Ensure the vehicle is parked on a flat, level surface and is powered off before beginning.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Check wiring and connectors for any visible damage or corrosion.
Clean the sensor area to remove any debris or dirt.
If damaged, replace the wheel speed sensor with a new one, adhering to torque specifications (typically around 7-10 ft-lbs) for mounting bolts.

3. Tire Inspection and Pressure Adjustment

Using a tire pressure gauge, check the pressure of all tires.
Inflate or deflate each tire to the recommended pressure (usually found on the driver’s door jamb).
Inspect tires for uneven wear, which may indicate alignment or balance issues, and replace if necessary.

4. Brake System Inspection

Check brake pads and rotors for wear; replace if they are below minimum thickness.
Ensure brake fluid is at the proper level and free of contamination.
Inspect ABS (Anti-lock Braking System) module connections for corrosion or damage.

5. System Reset

Perform a soft reset by holding down the two scroll wheels on the steering wheel until the touchscreen restarts.
Monitor the traction control light to see if it remains illuminated after the reset.
